Full textAbstract:
Blackleg, caused by Leptosphaeria maculans (Desmaz) Ces. & de Not (anamorph = Phoma lingam), is an economically important disease of canola (Brassica napus L.) worldwide and was first detected in North Dakota in 1991 (3). L. maculans can be categorized into one of several pathogenicity groups (PGs) on the basis of the interaction phenotypes in differential canola cvs. Westar, Glacier, and Quinta by using a standard screening protocol in the greenhouse (4). With this system, PG1 strains are weakly virulent and PG2, PG3, and PG4 are highly virulent. The predominant strains of L. maculans in North Dakota are PG1 and PG2 (3). In cooperation with the Oilseed Pathology Lab in the Department of Plant Science, University of Manitoba, blackleg-infested canola stubble was collected arbitrarily from fields in North Dakota during August and September of 2003. Isolates of the pathogen were obtained by plating surface-sterilized (2% NaOCl), collected stubble on V8 agar containing 0.03% chloramphenicol at 22°C under continuous cool-white fluorescent light. Pycnidiospores were harvested from single pycnidia after 14 days of incubation with the Miracloth filtering method (2) and stored at -20°C. Each isolate was passed once through cv. Westar to maintain virulence. Isolates were confirmed as being L. maculans by the presence of characteristic pink pycnidia formed on V8 agar and the characteristic symptoms caused on inoculated cotyledons of cv. Westar. The PG test was performed using a standard screening protocol (4) and was repeated three times for each isolate. For each isolate, 12 7-day-old cotyledons of each differential cultivar were wound inoculated with 10 μl of a pycnidiospore suspension (1 × 107 per ml). Disease severity on cotyledons was assessed 12 days after inoculation with a 0 to 9 scale (0 to 2 = resistant; 3 to 6 = intermediate; and 7 to 9 = susceptible). A total of 106 isolates were obtained from the stubble collected from 47 fields. Of these isolates, three were characterized as PG1, 94 as PG2, six as PG3, and one as PG4; two isolates could not be characterized according to the PG system as described (4). PG3 isolates originated from two fields in Cavalier County and one field in Ward County. The PG4 isolate was from Cavalier County. To our knowledge, this is the first time highly virulent strains of PG3 and PG4 have been detected in North Dakota. PG3 and PG4 strains of L. maculans were found only recently in western Canada (1,2). The discovery of these PGs in North Dakota and western Canada has immense implication to canola breeding programs and blackleg control, since these PGs may cause greater levels of blackleg severity on canola cultivars that are resistant to only PG2 type isolates.

Full textAbstract:
Elemental sulfur is commonly applied for powdery mildew (Erysiphe necator) protection on winegrape (Vitis sp.). The product may be used in a diversified, integrated disease management system to help prevent fungicide resistance to products with other modes of action. Additionally, sulfur may be used as a control option in organic systems. Applications of sulfur have been known to cause phytotoxic injury to susceptible winegrape cultivars, particularly those stemming from fox grape (Vitis labrusca) parentage. To improve recommendations to producers in the northern Great Plains region of the United States, a comparison of injury incidence and severity, as well as effects on yield characteristics was undertaken for 13 regional cultivars exposed to three sulfur rates (0, 2.4, and 4.8 lb/acre a.i.) at a North Dakota State University Research Station near Absaraka, ND. Overall, four cultivars (Bluebell, Baltica, Sabrevois, and King of the North) of the 13 cultivars tested showed phytotoxic symptoms. Injury severity and incidence of these cultivars differed between years and across rates. ‘Bluebell’ showed consistent and severe sulfur injury symptoms. Injury to the other three susceptible cultivars tended to vary by the given environment, with King of the North generally showing the lowest injury response. Injury symptoms were not found to be associated with the overall yield or cluster weight. Results suggest that alternative spray programs that exclude sulfur-based fungicides should be recommended for ‘Bluebell’, ‘Baltica’, ‘Sabrevois’, and ‘King of the North’, whereas sulfur-based fungicides may be applied to ‘Alpenglow’, ‘ES 12-6-18’, ‘Frontenac’, ‘Frontenac Gris’, ‘La Crescent’, ‘Marquette’, ‘Somerset Seedless’, ‘St. Croix’, and ‘Valiant’. Observations on fruit ripening in 2014 suggest that future research is needed to determine if a reduction of fruit quality may occur in some seasons with repeated sulfur applications or with successive annual sulfur applications for susceptible cultivars if used in an organic production system.

The medical curriculum at the University of North Dakota School of Medicine and Health Sciences has recently been redesigned into a problem-based/traditional hybrid model that utilizes an integrated organ systems-based approach to teach basic and clinical sciences. The number of lecture hours in general has been greatly reduced, and, in particular, lecture hours in physiology have been reduced by 65%. Students learn basic science in small groups led by a faculty facilitator, and students are responsible for a great deal of their own teaching and learning. The curriculum is centered around patient cases and is called patient-centered learning (PCL). The curriculum includes traditional lectures and laboratories supporting faculty-generated learning objectives. Endocrine physiology is taught in year one, utilizing four weeks of patient cases that emphasize normal structure and function of endocrine systems. Endocrine physiology is revisited in year two, which is primarily focused on pathobiology. The PCL curriculum, with emphasis on the endocrine component, is described in detail along with key portions of an endocrine case.

Full textAbstract:
Owing to analytical advances, submicron particles as small as 0.1 μm can be characterized for chemical composition, size, and shape using scanning electron microscopy (SEM). Once these characteristics are determined, the individual particles can be grouped into categories that provide size, shape, and chemical/mineral distributions of the fine particle fraction.An important application of submicron particle analysis is in solving ash-related problems in coal combustion and gasification systems. The Energy & Environmental Research Center (EERC) at the University of North Dakota is involved in an international consortium formed by the Electric Power Research Institute (EPRI), with U.S. Department of Energy Morgantown Energy Technology Center support, to study ash-related problems associated with the cleaning of hot gases in advanced energy systems. Before the gases are sent through a gas turbine to produce electricity, the particulates are removed with ceramic filters. Filters designed to trap the ash have a tendency to become plugged with ash, eventually causing operational problems. The focus of the project is to characterize the ashes from several filter systems to determine the mechanisms by which difficult-to-clean ash is formed and how it blinds hot-gas filters.

Full textAbstract:
In August of 2011, the North Dakota State University Plant Diagnostic Lab received a hybrid corn (Zea mays) leaf sample from Burleigh County in south-central North Dakota (ND). The leaf had long, irregular, water-soaked lesions consistent with Goss's leaf blight of corn. Using a light microscope at 10× magnification, bacterial streaming was observed from the excised edge of leaf tissue. A bacterial suspension was created, streaked onto a semi-selective CNS medium (1), and incubated at 22°C. Dark yellow-orange colonies appeared on the medium after 5 days. Single colonies were subcultured onto additional CNS media. To verify the identity of the bacterial isolate, PCR amplification of the 16S ribosomal DNA from this isolate along with a known Clavibacter michiganensis spp. nebraskensis (Cmn) isolate collected in Indiana (4) was performed using the eubacterial universal primers 27f and 1525r (3). The 1,431-bp 16S rDNA region was obtained for each isolate and they were compared with each other and with those deposited in NCBI GenBank. Sequence alignment identified only one nucleotide difference between the ND isolate and the Indiana isolate. BLASTn search against the NCBI database showed the first 100 hits were described as C. michiganensis or unidentified Clavibacter sp. The ND isolate had a two-nucleotide difference with Cmn isolate NCPPB2581 (HE614873), and a three nucleotide difference was found with the C. michiganensis spp. michiganensis isolate NCPPB 382 (AM711867). To satisfy Koch's postulates, eight corn plants (Golden Cross Bantam) were grown in the greenhouse at 22 to 24°C. Four corn plants were inoculated at growth stage V4-V5 using a suspension of approximately 1 × 109 CFU/ml from cultures grown on CNS for 6 days. Wounds were created on the fifth leaf approximately 7 cm from the leaf tip using a tongue-seizing forceps outfitted with a rubber stopper composed of pins (2). Simultaneously, 1 ml of the bacterial suspension was delivered into the wounds through a hole on top of the rubber stopper. Four control plants were inoculated with sterile water in a similar fashion. No symptoms were observed on the control plants. After 6 days, long water-soaked symptoms were observed on leaves inoculated with the bacterial suspension. Using leaves with water-soaked lesions, the pathogen was re-isolated onto CNS media and subjected to PCR amplification, and the resulting amplicons were sequenced as before. The sequence of the amplicon from the re-isolation matched that of the original ND isolate. To our knowledge, this is the first account of Goss's leaf blight and wilt identified in ND. As the corn acreage and no-till production systems in the state have increased, the economic implications of this disease may become more significant. Recognition of symptoms and proper identification of this bacterial disease in the field should help reduce unnecessary foliar fungicide sprays. References: (1) D. C. Gross and A. K. Vidaver.

ISSN 0804–4643 The prolactin receptor (PRL-R), a member of the hematopoietin cytokine receptor superfamily, is widely distributed among mammalian tissues. To understand better the potential sites of action and onset of potential PRL responsiveness, the developmental distribution pattern of PRL-R mRNA expression in fetal and neonatal mice was examined. Fetal mouse tissues were collected at distinct stages from timed pregnancies. Following extraction of total RNA, onset of gene expression was evaluated via reverse transcription-polymerase chain reaction (RT-PCR) and Southern hybridization was employed for verification. Expression of PRL-R mRNA was first observed on day 14 in the liver and cranium and on day 15 in the kidney, lung and thymus gland. Pituitary and adrenal glands were positive for PRL-R at day 18 of gestation through to day 1 of postnatal life. Neither whole fetuses prior to day 14 (days 10–13) of gestation nor skin and bladder tissues from 2-day-old mice generated detectable RT-PCR signals for PRL-R. The presence of PRL-R mRNA in fetal thymus and spleen tissues suggests a possible role for PRL in the development of the immune system. Prolactin may act directly on the pituitary to influence its own secretion and/or that of other pituitary-derived factors, as evidenced by the presence of PRL-R mRNA in the pituitary glands of fetal and 1-day-old mice. These data are the first to show the presence of PRL-R gene expression in various organ systems in fetal mice and suggest that PRL is among several factors necessary to coordinate developmental activities.

Full textAbstract:
In September 2008, Veronica spicata ‘Royal Candles’ plants showing foliar symptoms typical of a rust infection were brought to the Plant Disease Clinic at the University of Minnesota. Plants were grown in a local nursery in Dakota County, Minnesota. A dark brown discoloration was apparent on the upper surface of the leaf with lighter brown pustules on the underside. Teliospores collected from the pustules were 2-celled with smooth walls and 36.35 to 48.87 μm long, 11.96 to 18.28 μm wide, and had a wall thickness of 1.33 to 2.61 μm, which is in accordance with type specimen of Puccinia veronicae-longifoliae (4). Pathogen identity was confirmed by comparison of the DNA sequence of nuclear ribosomal RNA region containing the internal transcribed spacer regions 1 and 2, 5.8S and the 5′ end of the 28S subunits between herbarium samples from the U.S. National Fungus Collection (BPI 841971/GenBank Accession JQ627617 and BPI 871789/GenBank Accession JQ627618) and the collected specimen (BPI 882886/GenBank Accession JQ627616). P. veronicae-longifoliae was first reported in the United States in 2004 from a commercial nursery in Michigan (2). Veronica rust has also been found in Michigan in 2005 and more recently in 2011 (1). The only other known report of Veronica rust in the United States occurred in Connecticut in 2007 (3). P. veronicae-longifoliae is not considered a quarantine pest by The Animal and Plant Health Inspection Service due to the limited host range, the host not being on the threatened or endangered list and the host being of little economic or environmental importance (2).

Mixed-phase stratus clouds are ubiquitous in the Arctic and play an important role in climate in this region. However, climate and regional models have generally proven unsuccessful at simulating Arctic cloudiness, particularly during the colder months. Specifically, models tend to underpredict the amount of liquid water in mixed-phase clouds. The Mixed-Phase Arctic Cloud Experiments (M-PACE), conducted from late September through October 2004 in the vicinity of the Department of Energy's Atmospheric Radiation Measurement (ARM) North Slope of Alaska field site, focused on characterizing low-level Arctic stratus clouds. Ice nuclei (IN) measurements were made using a continuous-flow ice thermal diffusion chamber aboard the University of North Dakota's Citation II aircraft. These measurements indicated IN concentrations that were significantly lower than those used in many models. Using the Regional Atmospheric Modeling System (RAMS), we show that these low IN concentrations, as well as inadequate parameterizations of the depletion of IN through nucleation scavenging, may be partially responsible for the poor model predictions. Moreover, we show that this can lead to errors in the modeled surface radiative energy budget of 10–100 Wm−2. Finally, using the measured IN concentrations as input to RAMS and comparing to a mixed-phase cloud observed during M-PACE, we show excellent agreement between modeled and observed liquid water content and net infrared surface flux.

Abstract Crossbred beef heifers (n = 23; initial body weight [BW] = 370 ± 12 kg) housed at the North Dakota State University Beef Cattle Research Complex in Fargo, ND, were used to evaluate the effects of a 250-d slow-release vitamin and mineral bolus on feedlot performance, feeding behavior, carcass characteristics, and liver mineral concentrations. Heifers were assigned to one of two treatments: 1) received no supplemental mineral or vitamin (CON, n = 12) or 2) received two boluses on day 0 (minimum of 3,740 mg Ca, 16,456 mg Mg, 112 mg Na, 11,220 mg Cu, 2,995 mg I, 2,805 mg Mn, 505 mg Se, 48,620 mg Zn, 468 mg Co, 824,296 IU vitamin A, 173,102 IU vitamin D3, and 4,121 IU vitamin E bases on company analysis; Reloader 250 Mineral Bolus, Cargill Inc., Minneapolis, MN; MIN, n = 11). Heifers were fed a total mixed ration containing corn silage, grass hay, dried distillers grains with solubles, and dry-rolled corn (16.05% crude protein, 1.44 Mcal/kg NEg) with no added vitamin or mineral supplement. Feed intake and number and time of visits were recorded for each heifer using the Insentec feeding system (Hokofarm Group B.V., the Netherlands) during the feeding period. Liver biopsies were collected from heifers on days 0, 69, and 134 of the feeding period for analysis of mineral concentrations and analyzed as repeated measures. Heifers were slaughtered after 150 or 169 d on feed, and carcass characteristics were determined. Final BW, average daily gain, dry matter index, gain:feed, and carcass characteristics were not influenced (P > 0.19) by treatment. Control heifers visited feeders more but spent less time per visit and ate less per visit compared with MIN heifers (P < 0.03). No differences (P > 0.06) in liver mineral concentrations were observed between treatments, and concentrations of Se, Cu, Mo, Mn, and Co decreased (P < 0.05) over the feeding period. In this experiment, the slow-release vitamin and mineral bolus evaluated failed to increase liver mineral concentrations during the finishing period or influence heifer performance and carcass characteristics.

Assessment at North Dakota State University is considered to be a conversation about learning outcomes enriched by data with a goal of improving student learning. On the classroom level, this focuses on developing techniques to assess course-related knowledge and skills but may also include techniques to assess learner reactions to teaching and their course-related learning, study skills, and self-confidence. On the program level, this consists of an assessment plan and a corresponding assessment report. These assessment plans identify how the entire curriculum will be assessed over time, whereas the report documents plan implementation. The report consists of the activities designed to collect information on the success of each course. These activities may be direct, indirect, or non-measures of student learning. The direct measures along with a few indirect measures provide answers to the university assessment committee on student learning assessment questions: “what did you do?,” “what did you learn?,” and “what will you do differently as a result of what you learned?”

Woody plant improvement research has been an active program at North Dakota State Univ. (NDSU) for many years. Eighteen cultivars have been introduced since 1986, and ≈10 additional releases are anticipated over the next 6 years. These superior, winterhardy cultivars have increased the inventory of adapted woody plants for landscape use in the northern plains, particularly USDA hardiness zones 3 and 4. Emphasis will be placed on recent introductions and promising plants for potential future release. An extensive, statewide cooperative evaluation program is conducted at seven sites throughout North Dakota and also at the NDSU Research Arboretum near Absaraka.

A funny thing happened on my way to becoming GODORT chair: after ten years as the regional Federal Depository Library coordinator at the University of Georgia, I accepted a new job outside of the government documents community. As of June 28, 2018, I am the associate dean of libraries for research and learning at North Dakota State University. Obviously, my new job was not on my radar when I agreed to run for GODORT chair-elect in 2017. And while I am no longer a depository coordinator, I am still tangentially involved with the depository community. NDSU is a shared regional with the University of North Dakota, and our regional depository coordinator—Susanne Caro, formerly of the University of Montana—reports to me. In fact, Susanne is the GODORT chair-elect, which makes North Dakota the nexus of GODORT for the next few years. Not bad for a state that, according to the Census Bureau, ranks forty-seventh in population!

Full textAbstract:
Experiments were conducted in 2013 and 2014 to evaluate the effects of training system and leaf removal treatments on yield and quality for ‘Frontenac’, an interspecific hybrid wine grape, at a research vineyard located near Absaraka, North Dakota. The experiment was structured as a randomized complete block design with a split-plot arrangement including four training system treatments (Geneva Double Curtain (GDC), High Cordon (HC), Vertical Shoot Positioned (VSP), Four-Arm Kniffin (4AK)), and four-leaf removal timing treatments (bloom, post-bloom, veraison, and a control, no removal) with eight replicates. In 2013, 1428 growing degree days (GDDs) accumulated in the 155 days between frost events. In 2014, 1156 GDDs accumulated in the 121 days between frost events, 272 GDDs less than the year prior. Even with the large GDD differences between years, there was no significant interaction between trellis type and leaf removal, and the main factor of leaf removal did not influence any of the fruit variables where data were collected. Combined data analysis showed no significant differences in fruit juice total soluble solids (TSS) or titratable acidity (TA). The fruit juice pH in 2013 was greater when grapes were grown in the VSP system compared to grapes grown in the other trellis systems. In 2014, live nodes and total shoots were greater for grapes grown on GDC and 4AK systems compared to grapes grown on the HC and VSP systems. Additionally, in 2014, grapes grown on the GDC system had a greater cluster number and yield when compared to grapes grown on the 4AK or VSP systems. These findings suggest that ‘Frontenac’ fruit TSS accumulation and TA were not affected by leaf removal or trellis system in North Dakota vineyards and that yield gains may be reached due to the training system without negatively affecting fruit quality.

Full textAbstract:
Macrophomina phaseolina, the causal agent of soybean charcoal rot, is widely present in soil and has been reported to cause yield losses of 30 to 50%, mainly in southern soybean production regions of the United States. (2). Charcoal rot was first reported in North Dakota during 2002, suggesting a range expansion for M. phaseolina (1). Charcoal rot has been occasionally observed in Iowa in individual soybean plants, but epidemics of the disease have not been recorded. During the 2003 growing season, a severe epidemic of charcoal rot was observed throughout the state. Diseased plants were first noticed in late July and by late August, patches of diseased plants wilted and died prematurely in many fields. The pith of diseased plants had a brown discoloration in taproots and lower stems. Symptoms were observed up to the 4th or 5th nodes, typical of charcoal rot. In some plants, no discoloration was evident. In discolored plants, microsclerotia of M. phaseolina were commonly observed in the epidermis, just beneath the epidermis, and inside taproots and lower stems of wilted plants. A systematic survey was conducted between late August and early September, 2003 to determine the prevalence and severity of charcoal rot in Iowa. The disease was observed in 60% of fields surveyed in northern Iowa (north of latitude 42.5°N), 90% in central Iowa (latitude 41.6 to 42.5°N), and 20% in southern Iowa (south of latitude 41.6°N). Incidence in surveyed fields ranged from 10 to 80%. One 80-ha field in Hampton (northern Iowa) had 50% disease incidence. An incidence of 80%, with extensive premature death prior to growth stage R6 (full seed), was observed in a 16-ha field east of Huxley (central Iowa). The fungus was isolated by splitting open the tap roots of a few representative symptomatic plants from 18 fields. Tissue colonized with microsclerotia of M. phaseolina was scraped, collected in sterile petri dishes, surface sterilized in 1% sodium hypochlorite, washed in distilled sterile water, and transferred to potato dextrose agar. The plates were incubated for 2 weeks at 22 ± 1°C on laboratory benches with a 12-h photoperiod. All resulting cultures produced abundant microscleorotia of M. phaseolina similar to those described by Smith and Wyllie (3). Pycnidia were observed in two cultures. August 2003 was the driest month on record in Iowa, which may have contributed to the outbreaks of this disease. Statewide, yield in Iowa soybean during 2003 was 1,976.1 kg/ha (2,798 kg/ha in 2002). The largescale epidemic of charcoal rot may have contributed to the overall reduction in soybean productivity in Iowa in 2003 (4). Since M. phaseolina also infects corn (2), and corn/soybean rotation is the most common cropping system in Iowa, efforts are needed to address the future risk of M. phaseolina to corn and soybean.

Spot blotch, caused by Cochliobolus sativus, has become an important disease on two-rowed barley cultivars in North Dakota. Information on the variability of virulence in C. sativus is essential for the development of spot blotch-resistant barley germ plasm. To establish the number and distribution of C. sativus virulence types in North Dakota, 22 isolates from the state were evaluated for their virulence on three differential barley genotypes: ND 5883, Bowman, and ND B112. Eleven additional isolates from Minnesota, South Dakota, Nebraska, Colorado, Japan, and China were included for comparison. Three pathotypes were identified from the thirty-three isolates tested based on the infection responses of the three host genotypes. These pathotypes were designated 0, 1, and 2 according to the coded triplet system of nomenclature. In North Dakota, pathotype 0 (exhibits low virulence on all three differentials) comprised 65%, pathotype 2 (exhibits high virulence on Bowman and low virulence on ND 5883 and ND B112) comprised 25%, and pathotype 1 (exhibits high virulence on ND 5883 and low virulence on Bowman and ND B112) comprised 10% of the total number of barley isolates examined. Within North Dakota, pathotype 1 was found in the east-central and northeastern region only, whereas pathotypes 2 and 0 were distributed throughout the state where samples were taken. Isolates with the pathotype 1 virulence pattern were identified in Colorado, Nebraska, Japan, and China. The remaining isolates collected outside North Dakota were pathotype 0. The information obtained from this study will facilitate the deployment of effective resistance to C. sativus in barley.

Full textAbstract:
Cryptodiaporthe canker, caused by Cryptodiaporthe corni (Wehm.) Petrak (anamorph Myxosporium nitidum Berk. & Curt.), is known to occur only on pagoda dogwood (Cornus alternifolia L. fil.) throughout its native range in eastern Canada and most of the eastern United States (1). Cankered branches with yellow-to-orange pigmented bark were recently observed on four ≈25-year-old C. alternifolia plants in an ornamental planting on the campus of North Dakota State University in Fargo. Although the fungal anamorph was usually present on all symptomatic materials, the teleomorph was also present on branches with larger diameters (>15 mm). Collections of infected branches made on 25 April 2001 contained perithecia but did not contain mature ascospores. Shoot growth began during the first week of May. Subsequent collections made on 11 May and 8 June 2001 contained perithecia with mature ascospores. A previous collection made on 12 October 2000 contained fully developed perithecia devoid of ascospores. A range of symptoms was present among the individual trees: one tree was severely cankered (up to 4 cm diameter) with many dead branches; one tree showed only minor damage with tip dieback on a few small twigs; and two trees had intermediate symptoms (1 cm diameter with cankers) with several dead branches. Pagoda dogwood is generally seed propagated, and differences in disease severity observed in these plants may be the result of genetic variation in resistance. Selection for resistant genotypes may be a possibility. Specimens (BPI 840955A and B) consisting of cankered branches containing both fungal morphs were deposited at the U.S. National Fungus Collections at Beltsville, MD. Although Cryptodiaporthe canker was previously collected from a native woodland tree in Minnesota (1), the current North Dakota specimens were collected from cultivated plants in a landscape setting. To our knowledge, this is the first report of Cryptodiaporthe canker in North Dakota. Management of this disease may need to be considered when recommending C. alternifolia for horticultural plantings. Reference: (1) S. C. Redlin and A. Y. Rossman. Mycologia 83:200, 1991.

Full textAbstract:
Brassica carinata A. Braun, commonly referred to as Ethiopian rapeseed, a near relative of collards and mustard, has become the object of increasing interest as an oil crop. It has been reported that B. carinata adapts better and is more productive than B. napus (canola) in adverse conditions, such as clay and sandy soils and under low management cropping systems (1). In late February 2012, symptoms typical of sclerotinia stem rot were observed in B. carinata trials (cultivars 090867 EM and 080814 EM) at the University of Florida, North Florida Research and Education Center located in Quincy, FL. Approximately 20 to 30% of the B. carinata cultivar 090867 EM were observed to have symptoms and approximately 5% of cultivar 080814 EM displayed symptoms. Stems had white mycelia growing on the outside, plants were lodging and spherical to cylindrical, 3 to 8 mm, and black sclerotia were found outside and inside bleached stems. Sclerotia from diseased stems were surface sterilized and placed in 9-cm diameter petri plates on quarter strength potato dextrose agar (PDA) amended with 25% lactic acid. Fungal cultures consisting of white mycelia and medium-sized (mean 4 mm), black, irregular sclerotia were consistently recovered and identified as Sclerotinia sclerotiorum (Lib.) de Bary based on morphological characteristics (3). Sequence analyses were conducted on mycelium by extracting fungal DNA with the Qiagen DNeasy Plant Mini Kit (Valencia, CA). PCR amplification was performed using primers ITS1 and ITS4. The BLAST search revealed that the sequence (GenBank Accession No. JX307092) had 99 and 100% sequence identity with S. sclerotiorum GenBank accessions JN013184.1 and JN012606.1. Pathogenicity was determined by inoculating six 1-month-old B. carinata plants (cultivars 090867 EM and 080814 EM) that were grown in greenhouse pots (20 cm in diameter). Mycelia plugs (8 mm in diameter) were excised from the colony margin after 6 days of incubation at room temperature (approximately 25°C), and placed on stems, at the soil line, of B. carinata plants. Six control plants were inoculated with noncolonized PDA plugs. All plants were enclosed in plastic bags that had been sprayed with water on the inside to maintain high humidity and kept in the laboratory at room temperature (approximately 25°C). Symptoms similar to those observed in the field were evident after 3 days on inoculated plants and S. sclerotiorum was reisolated. In the controls, no symptoms developed and the fungus could not be isolated. The experiment was repeated with similar results. The majority of rapeseed production is in North Dakota, where sclerotinia stem rot caused by S. sclerotiorum is a major fungal disease affecting production (2). Currently, there is no significant B. carinata production in Florida; however, interest in biofuels could lead to an increase in planted acreage and sclerotinia stem rot could become a significant disease problem in areas of Florida were B. carinata is planted. To our knowledge, this is the first report of sclerotinia stem rot of B. carinata caused by S. sclerotiorum in Florida. References: (1) M. Cardone et al. Biomass and Bioenergy. 25:623, 2003. (2) L.

This article presents views of Todd Torrence on introduction of online learning programs that can open paths from technical to technological. The University of North Dakota, which offers the only accredited online BSME program in the United States, is in a state where hydraulic fracturing has sharply increased oil production. The university has applied for accreditation of an online program offering a Bachelor of Science in Petroleum Engineering. The UND online BSME program covers the same material as its on-campus counterpart. North Carolina State has a 2+2 program where a student can go to a partnering university at the east and west ends of the state for the first two years of their undergraduate work. The University of North Dakota online BSME program covers the same material as its on-campus counterpart. Part of the accreditation process is assuring that the online degree is equivalent to the face-to-face degree. The challenge with undergrad online engineering programs is their sheer size and the time it takes to complete them, as compared with graduate programs.

10,000 ft horizontal drilling and hydraulic fracturing with 24 to 36 stages are prominent in Bakken petroleum system with great success. Although advanced automated drilling system with cutting edge comprehensive logging units are available from service providers to obtain various data assisting comprehensive real-time analysis, conventional positive displacement motor (PDM) with mud-pulse (MP) measurement while drilling (MWD)/logging while drilling (LWD) system is still widely applied in this area to steer and navigate the well bore in pay zone with cost-effectiveness and efficiency. In this paper, several field cases for MP MWD/LWD systems will be discussed and lessons will be summarized to help optimize rate of penetration (ROP), reduce non-productive rig time, and improve operators drilling practices.

Introduction:Biological safety cabinets (BSCs) are the primary means of containment used in laboratories worldwide. To ensure the proper functioning of BSCs, they need to be certified annually, at a minimum, per National Sanitation Foundation (NSF)/American National Standards Institute Standard 49.Objectives:A common problem most organizations face is that in many instances, the technicians who certify the cabinets are not accredited by the NSF. Additionally, in states or regions that do not have local NSF accredited field certifiers, it takes weeks to get a service request completed, thereby delaying the research work of the laboratory. Moreover, in such instances, the cost associated with cabinet certification and repair can be very high.Materials and Methods:This led the Office of Safety at the University of North Dakota to do a thorough cost-benefit analysis of developing an in-house BSC certification program. After completing the training and testing requirements for the NSF’s advanced accreditation program, the BSC certification program was initiated on campus.Results:The identified benefits led to the initiation of a program in both local and regional capacity for repair, maintenance, and certification of BSCs, and the university’s experiences were shared with other universities.Conclusions:By developing an in-house BSC certification program, the University of North Dakota was able to reduce wait times associated with service repairs, reduce costs, and generate revenue for the department. Furthermore, this led to improved hands-on training programs related to BSC use in laboratories working with biohazardous agents.

Full textAbstract:
Acreage of dry field pea (Pisum sativum) in North Dakota has increased approximately eightfold from the late 1990s to the late 2000s to over 200,000 ha annually. A coincidental increase in losses to root rots has also been observed. Root rot in dry field pea is commonly caused by a complex of pathogens which included Fusarium spp. and Rhizoctonia solani. R. solani isolates were obtained from roots sampled at the three- to five-node growth stage from North Dakota pea fields and from symptomatic samples received at the Plant Diagnostic Lab at North Dakota State University in 2008 and 2009. Using Bayesian inference and maximum likelihood analysis of the internal transcribed spacer (ITS) region of the ribosomal DNA (rDNA), 17 R. solani pea isolates were determined to belong to anastomosis group (AG)-4 homogenous group (HG)-II and two isolates to AG-5. Pathogenicity of select pea isolates was determined on field pea and two rotation hosts, soybean and dry bean. All isolates caused disease on all hosts; however, the median disease ratings were higher on green pea, dry bean, and soybean cultivars when inoculated with pea isolate AG-4 HG-II. Identification of R. solani AGs and subgroups on field pea and determination of relative pathogenicity on rotational hosts is important for effective resistance breeding and appropriate rotation strategies.

Full textAbstract:
During the growing season of 2012, 35 garlic plant samples were submitted to the University of Minnesota Plant Disease Clinic for disease diagnosis. Samples originated from multiple counties throughout Minnesota as well as Iowa, Wisconsin, and South Dakota. Symptoms first appeared at the time plants were starting to produce scapes. Symptoms included leaf discoloration that varied from yellow to purple, plant stunting, and leaf tip necrosis. In severe cases, the plants wilted and died. Bulbs of affected plants ranged from being soft and small to almost normal-looking. Symptoms were similar to those associated with phytoplasma infection in other plants. Total genomic DNA was extracted from 30 symptomatic samples and five asymptomatic leaf samples using a Qiagen DNeasy Plant Mini Kit (Qiagen, Germantown, MD) according to the manufacturer's instructions, and used with the universal phytoplasma primers P1/P7 in a direct PCR assay, and with P1/AYint in a nested PCR assay (2) to yield amplicons of 1.8 and 1.6 kb, respectively. Asymptomatic plants did not produce amplicons. Garlic cultivars displaying a range of symptoms tested positive for the presence of phytoplasma. These cultivars included: Susanville, Middle Eastern, Music, Ajo Rojo, Spanish Roja, Inchelium Red, Silver White, Asian Tempest, Chesnok Red, and Purple Glazer. The P1/P7 PCR products of 1,830 bp were purified using the PureLink PCR Purification kit (Life Technologies, Carlsbad, CA), and cloned in a pGem T-Easy vector system (Promega, Madison, WI). Sequences from a clone from each of Wisconsin, Iowa, and Minnesota were deposited in GenBank under the accession numbers KC000005, KC000006, and KC000007, respectively. A BLASTn similarity search revealed that the Wisconsin and Iowa isolates shared 99% homology to the sequences of 16SrI-A group phytoplasmas, aster yellows phytoplasma (AY389827), and aconitum proliferation phytoplasma (AF510323). The Minnesota isolate had 99% sequence homology to a 16SrI-B group phytoplasma, mulberry yellow dwarf phytoplasma (GQ249410). Also, the iPhyClassifier 16Sr group/subgroup classification based on similarity (3) analyses showed that the Wisconsin and Iowa phytoplasma isolates had 16S rDNA sequences in the 16SrI-A group with similarity coefficients of 0.97 and 1.00, respectively, to aster yellows witches'-broom phytoplasma AYWB (NC_007716). The same analysis revealed that the Minnesota phytoplasma isolate 16S rDNA sequence grouped with the 16SrI-B group onion yellows phytoplasma (NC_005303) with a similarity coefficient of 1.0. A phylogenic tree was deduced by the neighbor joining algorithm, clustering together the Iowa, Minnesota, and Wisconsin isolate sequences with a 16SrI group phytoplasma. Aster yellows phytoplasma has been reported in North America, but only in Canada (1). This is the first documented occurrence of 16SrI aster yellows group phytoplasma in garlic in the United States. The spring of 2012 was unusually warm, and high leafhopper pressure was observed throughout the Midwest; above average numbers of many ornamental crops and small grains were infected with phytoplasma. These events may have contributed to the phytoplasma infection in garlic. References: (1) A. H. Khadhair et al. Microbiol. Res. 157:161, 2002. (2) C. D. Smart et al. Appl. Env.

Dry bean (Phaseolus vulgaris L. cv. Pintoba) plants showing typical anthracnose symptoms were observed in three commercial fields in North Dakota (Towner, Steele, and Pembina counties) in July 2001. Disease incidence in all fields ranged from 5 to 20%. The fungus was isolated from leaves and pods on potato dextrose agar and identified as Colletotrichum lindemuthianum (Sacc. & Magnus) Lams.-Scrib. (3). Pathogenicity and race identification were determined on a set of 12 standard differentials (2). Three isolates, one from each county, were grown for 7 days in Mathur's medium. Spores were suspended in water and Tween 80 (0.1% vol/vol) and adjusted to 106 spores per ml. Thirty 2-week-old seedlings of each differential were inoculated with each isolate on the adaxial side of the primary leaves using a Paasche airbrush. Inoculated plants were incubated in moist chambers for 5 days at 20°C under 14 h of fluorescent light and then moved back to the greenhouse. Disease reaction was assessed 3 days later. Isolates of C. lindemuthianum races 7 and 73 obtained from J. Kelly (Michigan State University) were used as positive controls. Inoculations were repeated once. All three North Dakota isolates and the positive control for race 73 produced sporulating lesions on the differentials ‘Michelite’, ‘Cornell 49242’, and ‘Mexico 222’. No lesions were observed in the other differentials. An unidentified anthracnose race retrieved from a single plant in 1982 constitutes the first report of the presence of anthracnose in North Dakota (4). In 1992, Michigan breeding materials infected with race 73 were planted in North Dakota (1); upon detection, the infected plants were destroyed and the fields quarantined. The epidemics observed in the 2001 season, developed in sites distant from the places where the Michigan materials were planted and have been associated with a single seed source. To our knowledge, the presence of anthracnose race 73 reported here constitutes the first report of anthracnose in commercial dry bean fields in North Dakota. References: (1) J. D. Kelly et al.

Abstract This study compared patterns of δ15N and δ13C enrichment of pallid sturgeon Scaphirhynchus albus and shovelnose sturgeon S. platorynchus in the Missouri River, United States, to infer their trophic position in a large river system. We examined enrichment and energy flow for pallid sturgeon in three segments of the Missouri River (Montana/North Dakota, Nebraska/South Dakota, and Nebraska/Iowa) and made comparisons between species in the two downstream segments (Nebraska/South Dakota and Nebraska/Iowa). Patterns in isotopic composition for pallid sturgeon were consistent with gut content analyses indicating an ontogenetic diet shift from invertebrates to fish prey at sizes of >500-mm fork length (FL) in all three segments of the Missouri River. Isotopic patterns revealed shovelnose sturgeon did not experience an ontogenetic shift in diet and used similar prey resources as small (<500-mm FL) pallid sturgeon in the two downstream segments. We found stable isotope analysis to be an effective tool for evaluating the trophic position of sturgeons within a large river food web.

Full textAbstract:
Fusarium dry rot of potato can be caused by several species of Fusarium, but F. sambucinum is considered the primary cause in stored potatoes in North America and Europe (2). Potato tubers of cvs. Shepody and Russet Burbank with severe dry rot were collected from a commercial processing storage facility in central North Dakota during 2003–2004. Pathogen isolations were made from infected tubers on one-half strength acidified potato dextrose agar (APDA). Only F. graminearum was isolated from all rotted tubers used. Identification was based on colony morphology and conidial and perithecial characteristics, which included a carmine coloration of the underside of the agar and white fluffy mycelium on APDA, the presence of black perithecia on carnation leaf agar, and large distinctive macroconidia (1). The identity was confirmed by the Fusarium Research Institute at Pennsylvania State University. Pathogenicity was tested in potato tubers and greenhouse-grown potato plants cv. Atlantic. Nine tubers were wounded by removal of a plug of tissue with a cork borer, 3 mm in diameter and 5 mm deep, and inoculated by placing either 100 μl of a conidial suspension (5 × 104 conidia per ml) from a 7-day-old culture or a mycelial plug, 3 mm in diameter, from a 7-day-old culture in the wound. Nine tubers wounded and treated with either sterile distilled water or one-half strength APDA served as controls. Plant inoculations were performed by cutting a slit in the lower stem with a sterile scalpel and placing a cotton collar saturated with a conidial suspension (5 × 104 conidia per ml) around the wound and held in place with a clothespin. Four plants were inoculated with a conidial suspension, and four plants were treated with sterile distilled water. All tubers inoculated with either Fusarium treatment developed typical potato dry rot symptoms consisting of a brown, dry decay with mycelium lined cavities, and F. graminearum was reisolated from all symptomatic tubers. The control tubers did not develop symptoms. No symptoms developed in any of the greenhouse inoculated plants. Fifteen isolates were tested for sensitivity to thiabendazole, and all were sensitive with EC50 (50% effective concentration) values ranging from 0.8 to 3.7 μl/ml. The results indicate that F. graminearum can cause dry rot of potato, and to our knowledge, this is the first report of F. graminearum as a cause of potato dry rot. These results have epidemiological implications in the persistence, spread, and management of F. graminearum in cereals and potatoes, since potato is often used in rotation with other hosts of F. graminearum, including wheat, barley, and corn.

The oil boom in North Dakota is aided by hydraulic fracturing, often referred to as fracking. Fracking uses a pressurized water, sand, and chemical mixture to break through layers of rock and release oil and gas. This procedure produces hundreds of truckloads of wastewater for each fracked well. In this study, we analyze the financial feasibility of a system of wastewater recycling and reuse to reduce total truck use and to conserve water supplies. We present a spatial mathematical programming model to assess the minimum cost of dealing with the potentially treatable portion of the fracking wastewater that flows back from North Dakota oil wells after fracking. Results of modeling demonstrate that mobile on-site treatment plants would be cost-effective. Both the public and private sectors have incentives to support the development of appropriate recycling technologies.

Full textAbstract:
Abstract On 24 February 2019, strong winds behind an Arctic cold front led to widespread blowing snow across the northern Great Plains including areas in eastern North/South Dakota and western Minnesota. Impacts of the event ranged from blizzard conditions in northwest Minnesota to sporadic, minor reductions in visibility across the region. This study documents the event using remotely sensed observations from platforms including geostationary and polar-orbiting satellites, an S-band radar, and time-lapse images from a camera located at the University of North Dakota in Grand Forks, North Dakota. Blowing snow is observed as plumes that resemble horizontal convective rolls (HCRs). Variations in near-infrared imagery are documented, and supporting observations suggest this is due to the occurrence or absence of clouds on top of the blowing snow layer. While lack of in situ observations preclude further investigation of physical differences between plumes, the utility of the Geostationary Operational Environmental Satellite-16 (GOES-16) satellite to operational forecasters is discussed. Improvements to spatial, radiometric, and temporal resolution courtesy of the Advanced Baseline Imager (ABI) on board GOES-16 allows for daytime detection of blowing snow events that previously, was only possible with instruments on board polar-orbiting satellites. This has improved Impact-Based Decision Support Services (IDSS) at National Weather Service offices that deal with the hazard of blowing snow.

Full textAbstract:
Ascochyta blight, caused by Ascochyta rabiei, is a serious disease of chickpea (Cicer arietinum) and fungicide applications are used to manage the disease in the North Central plains (4). During the 2010 growing season, a commercial field near Stanley, SD was treated with pyraclostrobin (Headline, BASF, NC) and called a management failure by the grower. Similarly, limited efficacy of pyraclostrobin was observed in an ascochyta research trial near Scott's Bluff, NE. In both locations, symptoms and signs consistent with A. rabiei infection existed on leaves, stems, and pods; namely, circular brown lesions with concentric rings of dark brown pycnidia. Symptomatic samples were collected, disinfected with 95% ethanol for 1 min, rinsed with sterile water, placed in 0.5% NaOCl for 1 min, and rinsed again with sterile water for 1 min (4). Samples were air dried, placed on potato dextrose agar (PDA) plates for 3 to 7 days, and colonies with morphological characteristics typical of A. rabiei were single-spored and transferred to new PDA plates and incubated for 7 to 14 days. Three and six putative A. rabiei isolates were obtained from South Dakota and Nebraska samples, respectively. Morphological characteristics were consistent with A. rabiei; cultures were brown with concentric rings of dark, pear-shaped pycnidia with an ostiole, and conidia were hyaline, single-celled, and oval-shaped (2). Comparison of the internal transcribed spacer (ITS) region amplified from the genomic DNA of 3-day-old liquid cultures using ITS4/ITS5 primers by BLASTN searches using the nr database in GenBank (Accession Number FJ032643) also confirmed isolates to be A. rabiei. Mismatch amplification mutation assay (MAMA) PCR was used for detection of sensitive and resistant isolates to QoI fungicides (1). Confirmation of the presence of the G143A mutation was carried out by cloning an mRNA fragment of the cytochrome b gene using cDNA synthesized from total RNA of A. rabiei and CBF1/CBR2 (1,3). Total RNA was extracted from 3-day-old liquid cultures and it was used instead of genomic DNA for this PCR to avoid large intronic regions commonly present in mitochondrial genes. The G143A mutation has previously been correlated with resistance to QoI fungicides in other fungal plant pathogens (3). Also, these isolates were determined to be QoI-resistant in vitro by PDA amended with a discriminatory dose of 1 μg/ml of azoxystrobin (4). To our knowledge, this is the first report of QoIresistant A. rabiei isolates causing infections on chickpeas in South Dakota and Nebraska. QoI-resistant isolates were reported in North Dakota and Montana in 2005 and 2007, respectively (4). Of nearly 300 isolates collected from these states from 2005 and 2007, approximately 65% were determined to be QoI resistant (4). The widespread occurrence of QoIresistant isolates and reduction of fungicide performance in fields led the North Dakota State University Cooperative Extension Service to actively discourage the use of QoI fungicides on chickpeas in North Dakota and Montana (4). It is likely that similar recommendations will need to be adopted in South Dakota and Nebraska for profitable chickpea production. References: (1) J. A. Delgado, 2012 Ph.D. Diss.

Full textAbstract:
Maize has become a profitable alternative for North Dakota (ND) farmers and ranchers. However, U.S. northern industry hybrids still lack cold and drought stress tolerance as well as adequate grain quality for ethanol and feedstock products. Moreover, there is a need to increase the value of feedstock operations before and after ethanol utilization. The ND maize breeding program initiated the development of hybrids with high quality protein content through the Early Quality Protein Maize for Feedstock (EarlyQPMF) project. The North Dakota State University (NDSU) maize breeding program acts as a genetic provider to foundation seed companies, retailer seed companies, processing industry, and breeders nationally and internationally. In the past 10 years, NDSU was awarded 9 PVP maize certificates and released 38 maize products. Within those, 13 inbred lines were exclusively released to a foundation seed company for commercial purposes. In addition, 2 hybrids were identified for commercial production in central and western ND.

This study documents outcomes, including student career choices, of the North Dakota Institutional Development Award Networks of Biomedical Research Excellence program that provides 10-week, summer undergraduate research experiences at the University of North Dakota School of Medicine and Health Sciences. Program evaluation initiated in 2008 and, to date, 335 students have completed the program. Of the 335, 214 students have successfully completed their bachelor’s degree, 102 are still undergraduates, and 19 either did not complete a bachelor’s degree or were lost to follow-up. The program was able to track 200 of the 214 students for education and career choices following graduation. Of these 200, 76% continued in postgraduate health-related education; 34.0% and 20.5% are enrolled in or have completed MD or PhD programs, respectively. Other postbaccalaureate pursuits included careers in pharmacy, optometry, dentistry, public health, physical therapy, nurse practitioner, and physician’s assistant, accounting for an additional 21.5%. Most students electing to stop formal education at the bachelor’s degree also entered fields related to health care or science, technology, engineering, and mathematics (19.5%), with only a small number of the 200 students tracked going into service or industries which lacked an association with the health-care workforce (4.5%). These student outcomes support the concept that participation in summer undergraduate research boosts efforts to populate the pipeline of future researchers and health professionals. It is also an indication that future researchers and health professionals will be able to communicate the value of research in their professional and social associations. The report also discusses best practices and issues in summer undergraduate research for students originating from rural environments.

Full textAbstract:
During August 2003, soybean (Glycine max) plants from Richland County, North Dakota with white-to-yellow, lemon-shaped structures on the roots were brought to the North Dakota State University Plant Diagnostic Laboratory. To confirm that the structures were females of a cyst nematode, they were crushed and observed microscopically to determine if nematode eggs and second-stage juveniles were present. Morphology of the second-stage juveniles was consistent with Heterodera glycines, the soybean cyst nematode (SCN). A survey was conducted in soybean fields in 34 km2 around the field in which the samples originated. Ten of twenty fields surveyed had visible females on the roots of plants. Symptoms observed in those fields included patches of stunted, chlorotic, and dead plants. Soil samples were collected from selected areas within eight fields, eggs were extracted using standard soil sieving techniques, and egg numbers were determined. Egg numbers ranged from 550 to 20,000 eggs per 100 cm3 of soil. SCN collected from two different fields, designated as Dwight and LaMars, were used to determine their HG Type. Standardized procedures (1) were used in a growth chamber set at 27°C with 16-h days. Pots in the test were organized in a completely randomized design with three replicates; the test was repeated over time. After 30 days, females were extracted from roots and counted, and a female index (FI) was calculated for each indicator line (1). The mean number of females on susceptible standard cv. Lee 74, was 110. The Dwight SCN population had an FI of 5.3 on plant introduction (PI) 88788, 1.5 on PI 209332, 5.8 on PI 548316 (Cloud), and 0 on all other indicator lines. The LaMars population had an FI of 1.0 on PI 88788, 3.1 on PI 548316 (Cloud), and 0 on all other indicator lines. These results indicate that both SCN populations tested are HG Type 0. To our knowledge, this is the first report of SCN on soybean in North Dakota. Because other hosts of SCN, as well as soybean, are economically important in North Dakota, such as dry edible bean (Phaseolus vulgaris) and dry pea (Pisum sativum), this disease could adversely impact several commodities throughout the state.
