Abstract:
The C programming language is infamous for its ability to be exploited,thus it raises several security concerns. This thesis aims to investigate whether Rust can successfully prevent commonly known C programming errors and if it is a safe choice as a low-level programming language. This was done by selecting a total of 20 commonly known critical C programming errors and implementing them in both C and in Rust to observe the outcome and attempt to draw a conclusion from a safety point of view. The results show that 55% of programming errors were inexpressible by Rusts language design, 30% were detected by the compiler and 15% were flagged faults. The results for the sameprogramming errors in C showed that 85% went completely undetected by the C compiler, thus being unflagged faults, whereas 15% were flagged faults. Based on the results presented in this thesis one might conclude that Rusts language design yields better results than the C languagedesign. Thus, for the chosen programming errors Rust provides a safer alternative to C.

Abstract:
Rust is a new systems programming language designed with a focus on bare metal performance, safe concurrency and memory safety. It features a robust abstraction mechanism in the form of traits, which provide static overloading and dynamic dispatch. In this thesis, we present MiniRust—a formal model of a subset of Rust. The model focuses on the trait system and includes some advanced features of traits such as associated types and trait objects. In particular, we discuss the notion of object safety—the suitability of a particular trait for creating trait objects—and we formally determine very general conditions under which it can be guaranteed. To represent the runtime semantics of MiniRust programs, we develop an explicitly-typed internal language RustIn, for which we prove type safety, and we show that well-typed MiniRust programs can be translated to well-typed RustIn programs. Finally, we adapt the informally-described Rust trait coherence rules to our model and we show that they are sufficient to ensure that overloads are always well-determined, even in the presence of library extensions.

Abstract:
Wheat leaf rust, caused by Puccinia triticina (Pt), and wheat stripe rust caused by P. striiformis f. sp. tritici (Pst) are important foliar diseases of wheat (Triticum aestivum L.) worldwide. Breeding for disease resistance is the preferred strategy of managing both diseases. The continued emergence of new races of Pt and Pst requires a constant search for new sources of resistance. Winter wheat accessions were evaluated at seedling stage in the greenhouse with races of Pt and Pst that are predominant in the North Central US. Association mapping approach was performed on landrace accessions to identify new or underutilized sources of resistance to Pt and Pst. The majority of the accessions were susceptible to all the five races of Pt and one race of Pst. Association mapping studies identified 29 and two SNP markers associated with seedling resistance to leaf rust and stripe rust, respectively.

Abstract:
This investigation was carried out for the characterisation and chromosomal locations of resistance to rust diseases in common wheat and durum wheat recombinant inbred line (RIL) populations. A new seedling stripe rust resistance gene (tentatively named YrAW10) was identified in common wheat landrace Aus27696. This gene is effective against both pre-2002 and post-2002 Australian Puccinia striiformis f. sp. tritici (Pst) pathotypes. YrAW10 was located in 3BL-A02-FL-0.22 deletion bin of chromosome 3B and was flanked by SNP markers KASP_13376 and KASP_8775. Yr29/Lr46-linked marker SNPLr46G22 indicated the presence of this gene in Aus27696. The presence of Lr16 was confirmed on the basis of infection type produced by Aus91433 and controls (Thatcher + Lr16 and Exchange) against Puccinia triticina (Pt) pathotype 104-1,3,4,6,7,8,9,10,12+Lr37 and linked marker location in the short arm of chromosome 2B. Lr16 was not effective against the Pt pathotypes used in field study. Genotype C16.14 was proved to carry at least two adult plant resistance (APR) genes located on chromosomes 1D and 3B through iSelect 90K SNP based selective genotyping of C16.14/Aus91433 RILs. The chromosome 3B located resistance was proved to be Lr74 through genotyping of markers closely linked with this gene. In addition to Yr29/Lr46, two other consistent QTL for stripe resistance were detected in Arrivato/Bansi RIL population through DArTseq mapping. QYr.sun-1BS.1 corresponded to Yr24 and QYr.sun-1BS.2 was temporarily named YrAr. Both of these genes produced intermediate responses when present alone. Two QTL located on different linkage groups of chromosome 2B were identified in addition to Lr46/Yr29. QLr.sun-2B.1 appeared to be either a new gene or an allele of Lr16. Aus27506 was shown to carry QLr.sun-2D in addition to Lr46 and QLr.sun-2B was contributed by Aus27229 in Aus27506/Aus27229 population. QLr.sun-2D and QLr.sun-2B appears to be new loci. Comparison of chitin accumulation in the flag leaves with the performance of QTL indicated that combination of two QTL prevent the fungal growth resulting in low disease severity.

Stripe rust (caused by Puccinia striiformis f. sp. tritici) and leaf rust (caused by Puccinia triticina) are the top two diseases of winter wheat (Triticum aestivum) with a 20-year average yield loss of 4.9% in Kansas. Due to the significant yield losses caused by these diseases, the overall objective of this research was to identify environmental variables that favor stripe and leaf rust epidemics. The first objective was to verify the environmental conditions that favor P. triticina infections in an outdoor field environment. Wheat was inoculated with P. triticina and exposed to ambient weather conditions for 16 hours. Number of hours with temperature between 5 to 25°C and relative humidity >87% were highly correlated and predicted leaf rust infections with 89% accuracy. The results of this outdoor assay were used to develop variables to evaluate the association of environment with regional leaf rust epidemics. Before regional disease models can be developed for a forecast system, suitable predictors need to be identified. Objectives two and three of this research were to identify environmental variables associated with leaf rust and stripe rust epidemics and to evaluate these predictors in models. Mean yield loss on susceptible varieties was estimated for nine Kansas crop reporting districts (CRD’s). Monthly environmental variables were evaluated for association with stripe rust epidemics (>1% yield loss), leaf rust epidemics (>1% yield loss), severe stripe rust epidemics (>14% yield loss) and severe leaf rust epidemics (>7% yield loss) at the CRD scale. Stripe rust and leaf rust epidemics were both strongly associated with soil moisture conditions; however, the timing differed between these diseases. Stripe rust epidemics were associated with soil moisture in fall and winter, and leaf rust epidemics during winter and spring. Severe stripe rust and leaf rust epidemics were associated with favorable temperature (7 to 12°C) and temperature (15 to 20°C) with relative humidity (>87%) or precipitation in May using tree-based methods of classification, respectively. The preliminary models developed in this research could be coupled with disease observations and varietal resistance information to advise growers about the need for foliar fungicides against these rusts in Kansas winter wheat.

Abstract:
Writing bug free computer code is a challenging task in a low-level language like C. While C compilers are getting better and better at detecting possible bugs, they still have a long way to go. For application programming we have higher level languages that abstract away details in memory handling and concurrent programming. However, a lot of an operating system's source code is still written in C and the kernel is exclusively written in C. How can we make writing kernel code safer? What are the performance penalties we have to pay for writing safe code? In this thesis, we will answer these questions using the Rust programming language. A Rust Kernel Programming Interface is designed and implemented, and a network device driver is then ported to Rust. The Rust code is analyzed to determine the safeness and the two implementations are benchmarked for performance and compared to each other. It is shown that a kernel device driver can be written entirely in safe Rust code, but the interface layer require some unsafe code. Measurements show unexpected minor improvements to performance with Rust.
Att skriva buggfri kod i ett lågnivåspråk som C är väldigt svårt. C-kompilatorer blir bättre och bättre på att upptäcka buggar men är ännu långt ifrån att kunna garantera buggfri kod. För applikationsprogrammering finns det tillgängligt olika högnivåspråk som abstrakterar bort den manuella minneshanteringen och hjälper med trådsäker programmering. Dock fortfarande så är större delar av operativsystemet och dess kärna är endast skriven i C. Hur kan vi göra programmering i kärnan säkrare? Vad är prestandakonsekvenserna av att använda ett säkrare språk? I denna uppsats ska vi försöka svara på dessa frågor genom att använda språket Rust. Ett programmeringsgränssnitt i Rust är implementerat i kärnan och en nätverksdrivrutin är portad till Rust. Källkoden skriven i Rust är analyserad för att bedömma säkerheten samt prestandan är jämförd mellan C och Rust implementationerna. Det är bevisat att vi kan skriva en drivrutin i enbart säker Rust om vi kan lita på några osäkra funktioner i gränssnittet. Mätningar visar lite bättre prestanda i Rust.

Abstract:
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is an economically important foliar disease of wheat (Triticum aestivum). In the last decade, losses from stripe rust in North Dakota (ND) have increased, peaking at 5% in 2015. Three research studies were conducted to address questions on the pathogen, varietal resistance, and integrated management. The objective of the first study was to (i) identify virulent phenotypes of Pst isolates collected from ND from 2015 to 2017 and assign races, and (ii) determine the effect of temperature on in vitro urediniospore germination, latency, and lesion spread. Across the three years, five races were detected with PSTv 37 being the most common. The highest urediniospore germination occurred at 12oC followed by 16oC. Pst isolates had shorter latency at 21oC and larger lesion spread at 16oC. The objective of the second study was to evaluate seedling resistance and adult plant resistance in the North Dakota State University spring wheat breeding program using races PSTv 37 and PSTv 52. Results from seedling experiments indicated only four and two lines were resistant to PSTv 52 and PSTv 37, respectively. Adult plant resistance experiments were unsuccessful in 2019, and will be conducted again in the future. The objective of the third study was to develop fungicide timing recommendations for wheat rust (stripe and leaf) based on varietal resistance and time of disease onset. Rust developed in five of the eight field trials, and timing of disease onset was categorized by growth stage (tillering, flag leaf, or early-flowering). Results indicated fungicide application timing was influenced by timing of disease onset and varietal resistance. When rust was detected at the tillering growth stage on the susceptible variety, the best time to apply a fungicide was at Feekes 9. When rust was detected at flag leaf or beyond on a susceptible variety, a fungicide application at Feekes 10.51 provided the adequate disease reduction and protection of yield. Results from these research studies provide a better understanding of Pst, determined seedling resistance in the breeding program, and provides field data to refine management recommendations for wheat rusts in ND.

Abstract:
The main aim of this study was to develop closely linked markers for rust resistance genes Lr48, Lr49 and Sr48. In addition, mapping of adult plant stripe rust resistance in a landrace Aus27284 was also performed. Close SNP-Lr48 associations were identified using the iSelect 90K Infinium Array. Five SNP markers co-segregated with Lr48 and IWB70147 mapped 0.3 cM proximal. Kompetitive allele-specific PCR (KASP) assays were developed for linked SNP. In contrast, the KASP markers developed from the iSelect 90K Infinium SNP array for Lr49 did not result in close marker-trait association. Sequence comparison of flow sorted chromosome 4B from parents VL404 (Lr49) and WL711 (lr49) resulted in close association of sunKASP_21 (0.4 cM) with Lr49. The Arina/Cezanne RIL population was used to develop markers linked with Sr48 using the DArTseq platform and the iSelect 90K Infinium SNP Array. DArTseq based linkage map located Sr48 on the short arm of chromosome 2D. Marker sun590 derived from a DArTseq marker mapped 0.4 cM distal to Sr48. Sr48 was earlier mapped in the long arm of chromosome 2A in the Arina/Forno RIL population based on repulsion linkage with Yr1. The detection of 2AL-2DS translocation in Forno through genomic in-situ hybridisation (GISH) appears to have resulted in pseudo-linkage to locate Sr48 in chromosome 2AL. Aus27284 was susceptible to stripe rust at the seedling stage and exhibited resistance in field experiments. Genetic analysis showed monogenic segregation and the resistance gene was temporarily designated YrAW11. YrAW11 was located on chromosome 3BS near the centromere and KASP¬_65624/KASP_58449 and KASP_53113 flanked this locus. The closely linked markers identified in this study were tested on a set of Australian and Nordic wheat genotypes to validate their suitability for marker assisted selection (MAS). The results indicated that IWB70147, sunKASP_21, sun590 and KASP-53113 can be used for MAS of Lr48, Lr49, Sr48 and YrAW11, respectively.

Abstract:
Recent trials of Antirrhinum majus cultivars have revealed a wide range of susceptibility to rust (Puccinia antirrhini). The best plants were used as parents in a breeding programme to produce a useful level of durable field resistance. The F1 generation was self-pollinated but the F2 to F4 were selectively cross-pollinated within lines. The segregating generations were grown outdoors at two sites in Surrey, where they were subject to natural rust epidemics encouraged by the use of spreader rows. Individual plants were selected for rust-resistance and horticultural quality. By the F4 generation, lines showed greater resistance to rust than existing varieties and were becoming uniform in flower colour, growth habit and horticultural quality. Many floral abnormalities arose, especially in the F3. Their expression was usually highly variable and was enhanced by environmental stress. Tests of rust isolates against individual antirrhinum plants showed that there is considerable genetic variation within the rust population. Some monitoring of resistant varieties is desirable to identify future changes in the rust population. The spread of spores between widely spaced patches of susceptible host was simulated using a computer, which indicated that small, isolated patches may escape infection. The effect of rate-reducing resistance is increased when plants are widely separated. This is in agreement with practical experience. The urediniospores of Puccinia antirrhini cannot survive the winter in Britain and, though teliospores are regularly produced, no alternate host is known. However, overwintered antirrhinum plants produce viable urediniospores which start epidemics in early summer: there is no need to postulate an alternate host in the British Isles. Treating antirrhinum as a summer annual might be an important hygienic measure, reducing the local build up of inoculum early in the season. Acceptable control of rust should be possible, provided only the more resistant varieties are grown.

Abstract:
This study focuses on saving multi-million-dollar losses caused by rust diseases of wheat. Genetic diversity assessment in a panel of landraces through phenotypic assays and genotyping with markers linked with known adult plant stem rust resistance genes revealed the presence of Sr55 and Sr58 individually and in combination. Sr2 and Sr57 were present in two and five landraces, respectively. Genotypes carrying putatively new sources for adult plant stem rust resistance were identified. Two consistent QTL; QSr.sun-5BL and QSr.sun- 7BL were identified from a pre-Green Revolution winter wheat landrace Aus27959. Based on physical position of QSr.sun-5BL in Chinese Spring (NRG v1.0), this QTL was shown to be different from the chromosome 5B located stem rust resistance gene Sr56. Hence, this QTL represents a new source for stem rust resistance. The uniqueness of QSr.sun-7BL remains to be determined. Genetic analysis of stripe rust resistance at the 4th leaf stage in Australian wheat cultivar Axe indicated the involvement of a single locus. The underlying locus was mapped on chromosome 7A and named as Yr75. Fine mapping of the Yr75-carrying genomic region identified close linkage of kompetitive allele specific PCR (KASP) markers sunKASP_427 (0.4 cM) and sunKASP_430 (0.3 cM). These flanking markers are 1.24 Mb (physical disctance; IWGSC RefSeq v1.0 genome assembly) apart. Scanning electron microscopic (SEM) observations showed significant variation in pollen size. In vitro pollen germination medium was standardized to achieve 70-80% germination in 30-40 minutes. Pollen viability study among a set of 12 wheat genotypes showed the viability of wheat pollen up to five hours under controlled conditions. These experiments demonstrated the conditions for initiating pollen mediated gene editing in wheat.

Stem rust, caused by the fungus Puccinia graminis f. sp. tritici, has historically been one of the most important diseases of wheat. Although losses have been much reduced in the last fifty years, new highly virulent races of the pathogen have recently emerged in East Africa. These new races are virulent on nearly all of the currently deployed resistance genes and therefore pose a serious threat to global wheat production. The spring wheat variety ‘Kingbird’ is thought to contain multiple quantitative trait loci (QTLs) that provide durable, adult-plant resistance against wheat stem rust. Stem rust-susceptible Kansas winter wheat line ‘KS05HW14’ was backcrossed to Kingbird and 379 recombinant lines were advanced to BC₁F₅ and then increased for testing. The lines were screened for stem rust resistance in the greenhouse and field in Kansas and in the field in Kenya over multiple years. We identified 16,237 single nucleotide polymorphisms (SNPs) with the Wheat 90K iSelect SNP Chip assay. After filtering for marker quality, linkage maps were constructed for each wheat chromosome. Composite interval mapping and multiple-QTL mapping identified seven QTLs on chromosome arms 2BL, 2DS, 3BS, 3BSc, 5DL, 7BL, and 7DS. Six QTLs were inherited from Kingbird and one QTL on 7BL was inherited from KS05HW14. The location of the QTL on 2BL is approximately at locus Sr9, 3BS is at Sr2, 3BSc is at Sr12, and 7DS is at Lr34/Yr18/Sr57. Although no QTL was found on 1BL, the presence of resistance gene Lr46/Yr29/Sr58 on 1BL in both parents was indicated by the gene-specific marker csLV46. QTLs on 2DS and 5DL may be related to photoperiod or vernalization genes. Pairwise interactions were only observed with race QFCSC, most notably occurring with QTLs 2BL and 3BSc. These results confirm that there are multiple QTLs present in Kingbird. Ultimately, the identification of the QTLs that make Kingbird resistant will aid in the understanding of durable, non-race-specific resistance to stem rust of wheat.

Abstract:
Continuous Deep Analytics (CDA) is a new form of analytics with performance requirements exceeding what the current generation of distributed systems can offer. This thesis is part of a five year project in collaboration between RISE SICS and KTH to develop a next generation distributed system capable of CDA. The two issues which the system aims to solve are computation sharing and hardware acceleration. The former refers to how BigData and machine learning libraries such as TensorFlow, Pandas and Numpy must collaborate in the most efficient way possible. Hardware acceleration relates to how the back-end of current generation general purpose data processing systems such as Spark and Flink are bottlenecked by the Java Virtual Machine (JVM). As the JVM abstracts over the underlying hardware, its applications become portable but also forfeit the opportunity to fully exploit the available hardware resources. This thesis aims to explore the area of Domain Specific Languages (DSLs) and code generation as a solution to hardware acceleration. The idea is to translate incoming queries to the system into low-level code, tailor suited to each worker machine’s specific hardware. To this end, two Scala DSLs for generating Rust code have been developed for the translation step. Rust is a new, low-level programming language with a unique take on memory management which makes it as safe as Java and fast as C. Scala is a language which is well suited towards development of DSLs due to its flexible syntax and semantics. The first DSL is implemented as a string interpolator. The interpolator splices strings of Rust code together, at compile time or runtime, and passes the result to an external process for static checking. The second DSL instead provides an API for constructing an abstract syntax tree, which after construction can be traversed and printed into Rust source code. The API combines three concepts: heterogeneous lists, fluent interfaces, and algebraic data types. These allow the userto express advanced Rust syntax such as polymorphic structs, functions, and traits, without sacrificing type safety.
Kontinuerlig Djup Analys (CDA) är en ny form av analys med prestandakrav som överstiger vad den nuvarande generationen av distributerade system kan erbjuda. Den här avhandlingen är del av ett project mellan RISE SICS och KTH för att utveckla ett nästa-generations distribuerat system kapabelt av CDA. Det är två problem som systemet syftar på att lösa: hårdvaruacceleration och beräkningsdelning. Det första handlar om hur BigData och maskininlärningssystem som sådan som TensorFlow, Pandas och Numpy måste kunna samarbeta så effektivt som möjligt. Hårdvaruacceleration relaterar till hur back-end delen i den dagens distribuerade beräknings system, såsom Spark och Flink, flaskhalsas av Javas Virtuella Maskin. JVM:en abstraherar över den underliggande hårvaran. Som resultat blir dess applikationer portabla, men ger också upp möjligheten att fullständigt utnyttja de tillgängliga hårdvaruresurserna. Den här avhandlingen siktar på att utforska området kring Domänspecifika Språk (DSLer) och kodgenerering som en lösning till hårdvaruacceleration. Idén är att översätta inkommande förfrågningar till låg-nivå kod, skräddarsydd till varje arbetar maskin’s specifika hårdvara. Till detta ändamål har två Scala DSLer utvecklats för generering av Rust kod. Rust är ett nytt låg-nivå språk med ett unikt vidtagande kring minneshantering som gör det både lika säkert som Java och snabbt som C. Scala är ett språk som passar bra tillutveckling av DSLer pågrund av dess flexibla syntax och semantik. Den första DSLen är implementerad som en sträng-interpolator. Interpolatorn sammanfogar strängar av Rust kod, under kompileringstid eller exekveringstid, och passerar resultatet till enextern process för statisk kontroll. Den andra DSLen består istället av ett API för att konstruera ett abstrakt syntaxträd, som efteråt kan traverseras och skrivas ut till Rust kod. API:et kombinerar tre koncept: heterogena listor, flytande gränssnitt, och algebraiska datatyper. Dessa tillåter användaren att uttrycka avancerad Rust syntax, såsom polymorfiska strukts, funktioner, och traits, utan att uppoffra typsäkerhet.

In order to prove the safety and correctness of Rust and to provide analysis tools for its use cases, it is necessary to construct a formal semantics of the language. Existing efforts to construct such a semantic model are limited in their scope and none to date have successfully captured the complete functionality of the language. This thesis focuses on the K-Rust implementation, which is implemented in a rewrite-based semantic framework called K, and expands it to include a larger subset of the Rust language. The K framework allows Rust programs to be executed by the defined semantic model, and the implementation is tested with several Rust programs by comparing the results of execution to the Rust compiler itself.

Type-safe languages undertake to prevent the type confusion vulnerabilities that arise in type-unsafe languages such as C++. One such type-safe language is Rust, which provides powerful type safety guarantees [1]. However, these guarantees are valid only for a single compilation unit. That is, they may not hold when multiple separately compiled processes communicate. In this work, we explore how type confusion vulnerabilities can still arise when multiple separately compiled, internally type-safe processes share information through inter-process communication (IPC). We propose safeIPC, a tool for eliminating IPC-facilitated type confusion in Rust. safeIPC is a Rust compiler extension that detects communications over IPC and inserts runtime checks to ensure that type safety is maintained. Programs instrumented with safeIPC throw a runtime error if the type of any data received over IPC is not equivalent to the type expected. Our analysis shows that safeIPC is effective in preventing type confusion vulnerabilities not prevented by Rust alone.

Abstract:
Stem rust and Yellow rust diseases are the two major wheat fungal diseases causing considerable yield losses in Turkey and all around the world. There are studies which are carried out to identify and utilize resistance sources in order to obtain resistant lines of wheat. However, virulent pathotypes are continuously being important threats to wheat production and yield. For that reason, new approaches for rapid identification are needed. The aim of this study was to investigate and to understand the structural and functional differences between the resistant and sensitive durum wheat cultivars to the plant fungal diseases of stem and yellow (stripe) rusts. To aim this, forty durum wheat recombinant inbred lines (RILs), which were previously determined to be resistant or sensitive to stem and yellow rust diseases, were investigated by the noninvasive Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) Spectroscopy. Also, classification of the resistant and sensitive lines depending on the structural and functional differences has been attempted. The FTIR spectra for stem rust disease showed that, resistant durum wheat lines had a significant increase in the population of unsaturation in acyl chains of lipid molecules, an increase in lipid and in total protein content and also an increase in carboxylic acids and alcohols. For yellow rust disease, resistant lines had a significant increase in hydrogen bonding and they had also a more ordered membrane structure. In Principal Component Analysis for stem rust disease, according to 3700-650 cm-1 region, amide III band (1213-1273 cm-1 region) and C-H stretching region (3020- 2800 cm-1), the resistant and sensitive groups were separated successfully. For yellow rust disease, according to 3700-650 cm-1 region, Amide A and Amide III bands, the resistant and sensitive lines were grouped distinctly. FTIR spectroscopy provides a useful approach to determine the differences in molecular structure of durum wheat RILs regarding resistance of lines to fungal diseases. However, further research is still needed to ensure if the structural and functional differences in biomolecules of the samples could be used as molecular markers for discrimination of rust resistant materials from rust sensitive ones.

Abstract:
Sunflower rust, caused by Puccinia helianthi (Schwein), is an economically important disease in North Dakota. Since 2008, sunflower rust incidence and severity have increased. Therefore, a four year study was initiated to examine the management strategies for the disease. A total of 19 fungicide efficacy and timing trials were conducted from 2008-2011. Results indicated that DMI and QoI chemistries can be used effectively to manage the disease. Timing trials indicated that disease control was highest when fungicide applications were made at R5.0-R5.8. Results indicate a fungicide application is warranted when rust severities at approximately 1% are found on the upper-four leaves at R5. To observe phenotype variability in the pathogen, a P. helianthi survey was completed in 2011 and 2012. Single-pustule isolates were obtained and virulence phenotypes were evaluated on a set of nine differentials. Race characterization was assigned based on virulence phenotypes. In 2011, the most commonly detected races were 300 and 304, while the most virulent was 776. In 2012, races 304 and 324 were the most commonly detected and the most virulent was 777. To identify new sources of rust resistance, the core-set of Helianthus annuus germplasm was obtained from the USDA-North Central Regional Plant Introduction Station. The accession lines were screened both in the greenhouse and the field. The accessions were screened in the greenhouse individually to races 300, 304, 336, 337, and 777. Lines were screened in the field to a mixture of P. helianthi isolates coding to 300, 304, 336, and 337. The majority of lines were susceptible in both the field and greenhouse. At both field locations, PI 431538, PI 432512, and PI 650362 had year-end severities under 1%. Similarly, PI lines 432512 and 650362 had resistant infection types across all five races. The results of these studies provide information and tools that are being used currently to manage rust and will contribute to management in the future.

Abstract:
Leaf rust caused by Puccinia hordei is an important disease of barley (Hordeum vulgare) in many regions of the world. Yield losses up to 62% have been reported in susceptible cultivars. The Rph5 gene confers resistance to the most prevalent races (8 and 30) of barley leaf rust in the United States. Therefore, the molecular mapping of Rph5 is of great interest. Genetic studies were performed by analysis of 93 and 91 F2 plants derived from the crosses 'Bowman' (rph5) x 'Magnif 102' (Rph5) and 'Moore' (rph5) x Virginia 92-42-46 (Rph5), respectively. Linkage analysis positioned the Rph5 locus to the extreme telomeric region of the short arm of barley chromosome 3H at 0.2 cM proximal to RFLP marker VT1 and 0.5 cM distal from RFLP marker C970 in the Bowman x Magnif 102 population. Synteny between rice chromosome 1 and barley chromosome 3 was employed to saturate the region within the sub-centimorgan region around Rph5 using sequence-tagged site (STS) markers that were developed based on barley expressed sequence tags (ESTs) syntenic to the phage (P1)-derived artificial chromosome (PAC) clones comprising distal region of the rice chromosome 1S. Five rice PAC clones were used as queries to blastn 370,258 barley ESTs. Ninety four non-redundant EST sequences were identified from the EST database and used as templates to design 174 pairs of primer combinations. As a result, 10 EST-based STS markers were incorporated into the 'Bowman' x 'Magnif 102' high-resolution map of the Rph5 region. More importantly, six markers, including five EST-derived STS sequences, co-segregate with Rph5. Genes, represented by these markers, are putative candidates for Rph5. Results of this study demonstrate the usefulness of rice genomic resources for efficient deployment of barley EST resources for marker saturation of targeted barley genomic region.

Abstract:
This study covered three aspects, namely; assessment of genetic diversity for rust resistance genes among released cultivars, inheritance of adult plant resistance (APR) in two North American wheat cultivars and genetic association between the stern rust resistance gene Sr3 9 and the stripe rust resistance gene YrSp. Queensland and northern New South Wales cultivars carried more diverse gene combinations in comparison to rest of the nation. Genetic diversity for all three rust diseases is a concern in Victoria and South Australia. There is need to release cultivars carrying combinations of resistance genes against three rust diseases. This will ensure environmentally safe control of rust diseases. Cultivars Jagger carried three genes for APR to stripe rust. Combinations of these genes provide high levels of resistance. Isolation of these genes individually was initiated and molecular mapping will determine identities of these genes. American workers detected the presence of Yr] 7 in at least one source of Jagger. Based on marker genotyping, the Jagger source used in this study did not carry Yr] 7. Cultivar Katepwa carried a single APR gene for stripe rust resistance. It is likely to be located on chromosome 2D. Repulsion linkage between the Triticum speltoides-derived stem rust and leaf rust genes Sr39/Lr35 and the stripe rust resistance gene YrSp was demonstrated. A recombination faction of 7.7:tl.5 cM between these genes was computed. These results refuted the previous location of YrSp in the short arm of chromosome 2B. Comparative results from other sources suggested the location of YrSp in the long arm of chromosome 2B. Progenies from three recombinant genotypes (Sr39Sr39YrSpyrSp) would enable the isolation of Sr39, Lr35 and YrSp in a single genotype. Such triple rust resistant genotype will be useful in improving rust resistance in future wheat cultivars.

Abstract:

Barley leaf rust (Puccinia hordei G. Otth) has been the cause of numerous and often devastating disease epidemics since the beginning of agriculture. Leaf rust is one of the most important diseases that affect barley (Hordeum vulgare L.) throughout the world. The pathogen Puccinia hordei is an obligate parasite. Symptoms of barley leaf rust may range from small chlorotic flecks to large pustules containing spores. Leaf rust epidemics reduce yields and grain quality.

Deployment of resistant cultivars is one of the most effective and economical means of controlling barley leaf rust. Identification and incorporation of new and effective sources of resistance are crucial to the success of barley breeding programs. Two types of resistance have been identified. They are race-specific resistance and partial resistance. A hypersensitive reaction by the host to infection of P. hordei isolates lacking corresponding virulence genes is indicative of race-specific resistance that is controlled by major genes. Sixteen race-specific genes (Rph1 to Rph16) have been identified. Partial resistance is generally polygenic and is often more durable that race-specific resistance.

The purpose of this research is to determine the inheritance of resistance to leaf rust in the barley experimental line VA 92-42-46, to identify the gene(s) conferring resistance, identify putative resistance related markers, and to map the gene(s) to one or more barley chromosomes using molecular markers. The Virginia barley line 92-42-46 was selected for this research project because it possesses resistance to P. hordei race 30, which has overcome resistance conferred by Rph7. Crosses were made between VA 92-42-46 and Moore, a susceptible cultivar to leaf rust. Inheritance studies were performed by screening F2 progeny and F2:3 families against race 8 and race 30 to determine the number of leaf rust resistance genes in VA 92-42-46. Allelism tests were performed to determine gene identity. A single dominant gene at the Rph5 locus or a tightly linked gene confers the resistance to P. hordei in VA 92-42-46.

Two populations, 'Moore' X VA 92-42-46 and 'Bowman' X 'Magnif', were used in this study for mapping molecular markers to provide comparison and confirmation of results. 'Magnif' possesses the resistance gene Rph5. Bulked segregant analysis was used to identify polymorphic RFLP and SSR markers that were used for mapping in each population. Linkage analysis revealed that the Rph5 gene maps to barley chromosome 3 (3H) above the centromeric region in the 'Moore' X VA 92-42-46 population. These findings agree with previous research that identified linkage between Rph5 and Rph7 on chromosome 3. The results obtained in this study do not support previous research that had reported the resistance gene Rph5 was located on barley chromosome 7 (5H). Further research should be conducted to verify the results of this study using the 'Bowman' X 'Magnif' population. The markers screened in the region above the centromere region of barley chromosome 3 were monomorphic for the 'Bowman' X 'Magnif' population except for the marker MWG561. Therefore, additional markers above the centromere of barley chromosome 3 should be screened.

Abstract:
Cultivated emmer wheat (Triticum turgidum ssp. dicoccum) is a good source of genes for resistance to several major diseases of wheat. The objectives of this study were to use genome-wide association analysis to detect genomic regions in cultivated emmer germplasm harboring novel resistance genes to four wheat diseases: stem rust, leaf rust, tan spot, and Septoria nodorum blotch (SNB). A natural population including 180 cultivated emmer accessions with a high level of geographic diversity was assembled as the association-mapping panel. This cultivated emmer panel was evaluated phenotypically by scoring reactions to stem rust, leaf rust, tan spot, and SNB and was genotyped using a 9K SNP Infinium array. After filtering for missing data points and minor allele frequency (MAF), 4,134 SNPs were used for association analysis using 178 emmer accessions. Based on principle component (PC) analysis, five subpopulations strongly associated with geographic origins were suggested by the first three PCs. Genome-wide association analysis revealed that 222, 42, 146, and 42 SNPs were significantly associated with resistance to stem rust, leaf rust, tan spot, and SNB, respectively, at the significant level of 1 percentile. Among the significant SNPs at the significant level of 0.1 percentile, ten, one, nine, and one co-located with known genes or QTL associated with resistance to the four diseases, respectively. The remaining significant SNPs were located in the genomic regions where no known resistance genes have been identified for the four diseases. This evidence suggests that some of the emmer wheat accessions carry novel genes conferring resistance to the four diseases. Additionally, 14, three, eight, and five LD blocks harboring at least one significant SNP were identified and might harbor putative QTL related to resistance to the four diseases, respectively. These studies provide information about the genomic regions in cultivated emmer that are associated with resistance to stem rust, leaf rust, tan spot, and SNB. Results from these studies provide guidance for selecting emmer accessions when decisions are being made about the parents that will be used for the development of new resistant germplasm and mapping populations for identifying novel genes conferring resistance to major wheat diseases.

Abstract:
Perchloroethylene (PCE) is a toxic contaminant that has been introduced into the environment over many years through industrial and agricultural wastes. Research has been done in the past to investigate PCE degradation by zero-valent iron (ZVI), green rust (GR) and a mixture of both. The combination of ZVI and green rust has been reported to be more effective for degrading PCE than either of them alone. Forming green rust electrochemically has the potential for depositing GR more effectively on the surface of ZVI where it will be able to more easily transfer electrons from ZVI to contaminants such as PCE. Therefore, the goal of this research was to determine the feasibility of electrochemically depositing green rust on zero-valent iron and to characterize it in terms of its composition, crystal properties and amount produced. XRD analysis was conducted to determine composition and crystal properties and a procedure was developed to measure the amount produced. Equipment was constructed to deposit green rust electrochemically onto ZVI. A chain of experiments with varying voltage, pH, time and amounts of ZVI were conducted to determine feasible experimental conditions for GR formation. Then, a method was developed to accurately measure the amount of surface oxides of iron deposited on the zero-valent iron substrate. This method was tested and found useful for measuring iron in: i) standard solutions of soluble iron with different concentrations of reagents; ii) suspensions with solid iron hydroxides by themselves; and iii) suspensions with solid iron hydroxides and ZVI. Electrochemical experiments were conducted and the amounts of iron hydroxides deposited on the ZVI surface were measured. XRD analysis of the deposits on the surface was conducted and the patterns of XRD-peaks were compared to that of type 2 – sulfate green rust.

It is hard to ensure correctness as software grows more complex. There are many ways to tackle this problem. Improved documentation can prevent misunderstandings what an interface does. Well built abstractions can prevent some kinds of misuse. Tests can find errors, but unless they are exhaustive, they can never guarantee the absence of errors. The use of formal methods can improve the reliability of software. This work uses the Why3 program verification platform to produce Rust code. Possible semantic-preserving mappings from WhyML to Rust are evaluated, and a subset of the mappings are automated using Why3's extraction framework.

Abstract:
Web applications are used more and more and mainly they are developed with the help of Javascript, but when you have heavy demanding processes in a web app, javascript can be too slow. The new language WebAssembly is an alternative that seeks to solve this problem. But unlike Javascript, there are many compilers for many different languages that have WebAssembly as their compilation goal. This means that the choice of language to compile from could make a difference when it comes to execution time. This article takes a closer look at two of the most popular languages, namely C and Rust, to see if language choice makes a difference. The differences between the languages are measured with the help of tests done between a server and a client and also with the help of an analysis of the WebAssembly code. The result shows that Rust is faster than C in matrix multiplication and insertion sort but the addition test shows that the languages are similar in speed.

Abstract:
Breeding for rust resistance in wheat relies on detailed understanding and availability of existing genetic diversity for rust resistance among global germplasm and knowledge of pathotypic variation among rust pathogens. This study involved assessment of genetic diversity for stem rust resistance in an international wheat nursery ZWB14, inheritance of stripe rust resistance in a common wheat landrace Aus27881 and molecular mapping of stripe rust resistance in genotype ZIZ13:69 imported from International Centre for Agricultural Research in the Dry Areas (ICARDA). All stage resistance (ASR) genes Sr8a, Sr17, Sr24, Sr30, Sr31 and Sr38 and adult plant resistance (APR) genes Sr2, Sr57 and Sr58 were present either singly or in different combinations in entries of ZWB14. Some entries were observed to carry additional uncharacterised resistance. Tri-genic inheritance of stripe rust resistance in Aus27881 was observed. Genotyping with Yr34 and Yr29 linked markers demonstrated the presence of these genes in Aus27881. Third locus that conditioned APR in Aus27881 appears to be new and needs further characterisation. Genotype ZIZ13:69 was demonstrated to carry ASR gene Yr1 and APR gene Yr29 based on greenhouse tests and marker genotyping, respectively. The targeted genotyping by sequencing (tGBS) assay of a set of RILs lacking Yr29 detected a new quantitative trait locus (QTL) on the long arm of chromosome 7D.

This investigation covers genetics of rust resistance in common wheat and durum wheat. Stripe rust resistance in AUS26615 was conferred by three QTL and these were temporarily named; QYr.sun-1B, QYr.sun-3D and QYr.sun-6B. QYr.sun-1B represented the previously named APR gene Yr29. The other two QTL appear to be new. The detection of QYr.sun-3D in late sown experiment points to its better expression at relatively higher temperature regimes. The all stage resistance gene, YrAW12, carried by AUS26674, was shown to be Yr34 based on its co-segregation with Yr34-linked marker sunKASP_112 and similar seedling expression. AUS26674/Avocet S RIL population was genotyped with Yr18 and Yr29 linked markers, and responses of RILs carrying different combination of these loci were compared. The RILs carrying combination of YrAW12, Yr18 and Yr29 produced adult plant responses equal to the parent AUS266674. Among the two gene combinations, YrAW12 and Yr18 combination, produced adult plant stripe rust score 3, lower than the score 4 exhibited by other two dual combinations). Four RILs that lacked YrAW12, Yr18 and Yr29 displayed stripe rust response scores 5 to 7 indicating the presence of an additional APR locus in AUS266674. Eight leaf rust genes (Lr1, Lr13, Lr16, Lr24, Lr26, Lr27+Lr31, Lr37 and Lr73) and 11 stem rust resistance genes (Sr2, Sr8a, Sr8b, Sr9b, Sr9g, Sr17, Sr23, Sr24, Sr30, Sr31 and Sr38) were postulated singly or in different combinations among a set 85 genotypes. Nine and five lines, respectively, appear to carry uncharacterised leaf rust and stem rust resistance. Adult plant leaf rust responses ranged from 2 to 6, while stem rust scores varied from 2 to 8. Genetic analysis of stem rust resistance in a durum landrace AUS26677 indicated involvement of a single resistance gene, temporarily named SrAW4. SrAW4 was located on chromosome 4B.

Abstract:
The 1985 and 1986 Cotton Reports have the same publication and P-Series numbers.
The use of sterol-inhibiting fungicides significantly decreased the number of aecial pustules on cotton leaves. The use of these fungicides did not significantly increase seed cotton yields when compared to check plots nor when compared to plots where a conventional, protective fungicide was used.
