Abstract:
Orobanche cumama wallr. is the sunflower root parasitic weed with special life stage in which seed germination and parasitism take place in the soil. In practice, applying microbial agents and trapping crop rotation are utilized separately, or just one of them is selected to control O. cumana. The development of the sunflower industry is severely constrained on the farmland, where there is high density of O. cumana’s seed banks. In this study, two biological control methods were combined to solve the problem of O. cumana parasitism. The bioassay experiment showed that the high concentration fermentation filtrates of Streptomyces rochei D74 could effectively inhibit the germination and growth of the germ tube of O. cumana seeds. As the concentration was increased to 3.1 mg/mL, O. cumana was almost unable to sprout. A two-year pot experiment revealed that the use of D74 agents and sunflower–maize–sunflower rotation together promoted sunflower growth, as shown by the biomass accumulation, plant height, and denser root systems. The combined method resulted in a significant decrease in the number of O. cumana parasitism, compared to one method alone. Additionally, it affected the bacterial community composition of sunflower rhizosphere, mostly leading to an increase in Streptomyces and Brevibacterium and a decrease in Arthrobacter. This experiment, combined with multiple biological control, means significantly reducing the parasitism of O. cumana, which provides an effective foundation for practical application.

Abstract:
Orobanche cumana is a root alloparasitic plant that drastically reduces sunflower (Helianthus annuus) production. In this study, transcriptomic changes of O. cumana-resistant (HZ2399) and O. cumana-sensitive (SQ25) sunflower seedlings were investigated at six time points (0–72 h) following O. cumana infection. The process of resistance to O. cumana was similar in HZ2399 and SQ25 seedlings, however, significantly higher regulatory activity was observed in the resistant plants. In HZ2399, most of the 54 upregulated genes were involved in phenylpropanoid biosynthesis, plant–pathogen interaction, and plant hormone signal transduction pathways. These genes were mainly associated with antioxidant responses, responses to stress, stimulation responses, and metabolic processes. The expression level of the three most significantly upregulated genes in HZ2399 (4CL2, EDS1, and TGA3) was significantly higher than that of SQ25, suggesting that they may be the main causes of O. cumana immunity in HZ2399. It is hypothesized that sunflower resistance to O. cumana parasitism is dependent on salicylic acid (SA), a disease resistance protein (TIR-NBS-LRR class) family (RPS4), and EDS1. The results of this study contribute to elucidating the mechanism of O. cumana resistance in sunflower and for the molecular breeding of O. cumana resistance.

Abstract:
AbstractBroomrapes (Orobanche and Phelipanche species, Orobanchaceae) are obligate root parasites of dicotyledonous plants. This taxonomic group includes seven weedy parasites of agricultural crops that damage vegetables, sunflower (Helianthus annuus L.), and legumes. Processing-tomato (Solanum lycopersicum L.) fields in Israel have been recently found infested with a new broomrape, first identified as nodding broomrape (Orobanche cernua Loefl.) based on its host. However, its morphology resembled the closely related sunflower broomrape (Orobanche cumana Wallr.), an obligate parasite of sunflower. The new race (CUCE) parasitized sunflower, tomato, and tobacco (Nicotiana tabacum L.) in vitro, in a polyethylene bag system and in pots. Its seeds germinated in response to strigolactones (orobanchol, 5-deoxystrigol, 2′-epiorobanchol, and GR24) and dehydrocostus lactone (DCL), whereas O. cumana seeds responded only to DCL and GR24, and O. cernua only to strigolactones. Based on morphological similarities with O. cumana, shared molecular markers with O. cumana, ability to parasitize sunflower and respond to sunflower-germination stimulants, it was concluded that CUCE is a new race of O. cumana, with a host range expanding to Solanaceae crops. While being an important noxious weed of sunflower, this new O. cumana race is currently spreading and posing a threat to processing tomato in Israel. This finding is an alarming indication that broomrapes can shift host range and that similar new races of O. cumana could potentially appear in other countries.

Abstract:
The genus Orobanche includes chlorophyll-lacking root parasites that parasitize many dicotyledonous species and causes severe damage to vegetable and field crops worldwide. Sunflower broomrape (Orobanche cumana Wallr.) is known in Eurasia as a specific parasite of sunflower, which differs from the nodding broomrape (O. cernua Loefl) in host specificity and morphological characteristics (3). Together with Egyptian broomrape (O. aegyptiaca Pers.), it seriously parasitizes sunflower (Helianthus annuus L.) in Israel (1). Prior to 2000, the local confectionary sunflower cvs. Ambar and Gitit proved to be resistant to the local O. cumana populations in Israel (2). A preliminary study, which we conducted in 1995 using the Vranceanu's differentials (4), indicated that O. cumana populations in Israel behave like the known race C. Using random amplified polymorphic DNA analysis, we also found a very low intraspecific diversity of this species in Israel at that time. However, in 2000, infection of the sunflower cvs. Ambar and Gitit was reported in two fields (Gadot and Afek) in northern Israel. In 2001 and 2002, O. cumana parasitized these cultivars in three more locations as much as 50 km apart (Tel-Adashim, Mevo-Hama, and Bet-Hilel). To determine the virulence of O. cumana populations on sunflower cultivars under controlled conditions, O. cumana seeds were collected in the above mentioned sunflower fields. In addition, we also used seeds from an O. cumana population collected in Alonim in 1997. This latter population did not infect the above mentioned ‘resistant’ sunflower cultivars in the field (2,); therefore, represented the previously known O. cumana populations in Israel. Resistant (Ambar) and susceptible (D.Y.3) sunflower cultivars were planted in separate pots that were differentially filled with soil that was inoculated with O. cumana seeds of the different populations. The experiment was performed in a full factorial arrangement with six replications. As expected, O. cumana from Alonim failed to attack the resistant sunflower. However, the O. cumana populations that were collected in the five other fields seriously attacked both sunflower cultivars, indicating higher virulence. O. cumana from all five new populations proved more virulent than the Alonim population on cvs. Ambar and D.Y.3. The occurrence of these new virulent populations could have several reasons including: (i) importation of virulent parasite seeds from abroad; or (ii) local development of virulence from previously avirulent populations. The latter could be favored by the continuous and repeated use of the available resistant varieties that are all based on a single resistance response (2). References: (1) H. Eizenberg and D. M.

Abstract:
Development of four Orobanche species, O. cumana, O. aegyptiaca, O. ramosa, and O. cernua, was compared on resistant and susceptible sunflower cultivars. Sunflower plants were infected by O. cumana, O. aegyptiaca, and O. ramosa, but not by O. cernua, in field and greenhouse studies. However, cultivating the hosts and parasites in a polyethylene bag system allowed the observation that sunflower induced O. cernua seed germination. This difference demonstrates that O. cernua is unique from the other three species. O. cumana, O. aegyptiaca, and O. ramosa attached to and developed tubercles on the susceptible sunflower ‘Adi.’ On the resistant ‘Ambar’ sunflower, a greater percentage of tubercles were degenerated or dead than on the susceptible cultivar. Thus, resistance of Ambar appears to manifest during tubercle development. Seed production of Adi sunflower was greatly reduced with infection by O. cumana.

Abstract:
Sunflower broomrape (Orobanche cumana Wallr.) has severely restricted the development of the sunflower industry in China, and more efficient and convenient control methods are urgently needed. In this experiment, we investigated the effects of N, P and silica fertilizers on the parasitism rate of O. cumana, as well as on the yield of sunflower and native microbial communities in the field. Firstly, pot experiments were conducted to select the most effective fertilization method and to determine the physiological and biochemical indexes of sunflowers. Subsequently, field application studies were carried out to determine the physiological indexes, yield, O. cumana parasitism on sunflower, and the effect on the indigenous microbial community. The results demonstrate that compared with the CNP treatment (Control), the number of parasites under the N1P5 treatment significantly decreased by 66.15%. The exogenous application of silica can significantly reduce the number of O. cumana parasites. The treatments with N1P5 (N/P = 1:5) and available SiO2 content higher than 40 mg/kg (NS2, NS3, SF2 and SF3) significantly increased superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) content in sunflower leaves. In the field, fertilization significantly decreased the number of O. cumana parasites. The S treatment improved the native microbial community structure and enriched beneficial microorganisms, including Vicinamibacteria and Pyrinomonadaceae. Additionally, applying the S treatment significantly increased sunflower yield by 23.82% and crude protein content by 20.20%. In summary, the application of silicon fertilizer can effectively improve the host microbial community, reduce O. cumana parasitism and improve the yield and quality of sunflower.

Abstract:
In this study, we report genetic characterization of Orobanche cumana, the causal agent of sunflower wilting in Serbia. The genetic diversity of this parasitic plant in Serbia was not studied before. Random amplified polymorphic DNA (RAPD) markers and partial rbcL gene sequences analysis were used to characterize the O. cumana populations at the molecular level. While phylogenetic analyses of RAPD-PCR amplicons were performed using unweighted pair-group Method analyses, rbcL gene sequences were analyzed using neigbor joining method and minimum spanning tree. Molecular analyses of RAPD-PCR analysis revealed high genetic diversity of O. cumana populations which indicated high adaptive potential of this parasitic weed in Serbia. Further analyses of rbcL gene using minimum spanning tree revealed clear differences among diverse sections of Orobanche genus. Although this molecular marker lacked the resolution to display intrapopulation diversity it could be a useful tool for understanding the evolution of this parasitic plant. Our results suggested that O. cumana has great genetic potential which can lead to differentiation of more virulent races which is important for determining crop breeding strategies for their control.

Abstract:
Effective control of the parasitic weed sunflower broomrape (Orobanche cumana Wallr.) can be achieved by herbicides application in early parasitism stages. However, the growing environmental concerns associated with herbicide treatments have motivated the adoption of precise chemical control approaches that detect and treat infested areas exclusively. The main challenge in developing such control practices for O. cumana lies in the fact that most of its life-cycle occurs in the soil sub-surface and by the time shoots emerge and become observable, the damage to the crop is irreversible. This paper approaches early O. cumana detection by hypothesizing that its parasitism already impacts the host plant morphology at the sub-soil surface developmental stage. To validate this hypothesis, O. cumana- infested sunflower and non-infested control plants were grown in pots and imaged weekly over 45-day period. Three-dimensional plant models were reconstructed using image-based multi-view stereo followed by derivation of their morphological parameters, down to the organ-level. Among the parameters estimated, height and first internode length were the earliest definitive indicators of infection. Furthermore, the detection timing of both parameters was early enough for herbicide post-emergence application. Considering the fact that 3-D morphological modeling is nondestructive, is based on commercially available RGB sensors and can be used under natural illumination; this approach holds potential contribution for site specific pre-emergence managements of parasitic weeds and as a phenotyping tool in O. cumana resistant sunflower breeding projects.

Abstract:
AbstractOrobanche cumana Wallr. is a holoparasitic plant for only sunflower, hence it is called as sunflower broomrape. Yield loss created by O. cumana which is generally 50 % can reach to 100 %. In this study, it was planned to perform molecular characterization of O. cumana germplasm as nine locations of Thrace region obtained from Trakya Agricultural Research Institute by using Single Nucleotide Polymorphism (SNP) markers, widely used in plant breeding programs, in Competitive Allele Specific PCR (KASP) assay which is a fluorescent tagged allele specific PCR method based, economic, reliable and easily repeatable genotyping technology. Databases and literature were scanned to spot variations on O. cumana genome which is not known clearly. So far, four SSR (Simple Sequence Repeat) marker (Ocum-197, Ocum-006, Ocum-023 and Ocum-151) regions showing polymorphic pattern were used for searching possible SNPs. Primer pairs were designed for amplification of the regions possibly having SNPs and PCR amplifications with these primer pairs were performed and 1 candidate deletion was detected on the amplicon which was amplified by Ocum-197 SSR marker. Following, the deletion was converted to KASP primers and KASP assay was performed. The deletion marker, Del-197, has grouped the samples from nine locations in the resulting allelic discrimination plot and infestation was performed according to this grouping, As a conclusion, Del-197 is considered as a selective marker for the ability to rapidly assay allelic variation at DNA markers for O. cumana populations that have effects on infestation results were evaluated as races, F, G, H and I in Thrace region.

Abstract:
Les plantes parasites telles que l'orobanche causent de nombreux dégâts sur les cultures et il existe peu de méthodes efficaces pour lutter contre ce fléau. L'objectif de la thèse a été de déterminer si des micro-organismes vivant en symbiose avec les plantes, les champignons mycorhiziens à arbuscules, peuvent être utilisés pour combattre les attaques d'Orobanche cumana sur le tournesol. Nous avons tout d'abord observé que la mycorhization de plants de tournesol réduit significativement leur infection par Orobanche cumana. Cet effet semble au moins en partie dû à une moindre germination des graines d'orobanche à proximité des plants mycorhizés. Nous avons ensuite montré que les champignons mycorhiziens euxmêmes produisent des inhibiteurs de la germination des graines d'orobanche. Enfin, nous avons mis au point un système in vitro permettant d'observer toutes les étapes précoces de l'infection de racines de tournesol par Orobanche cumana, en présence ou non de champignons mycorhiziens
Parasitic weeds such as broomrapes (Orobanche spp. ) can cause severe damage on crop plants, and efficient and sustainable control methods are needed. The aim of our work was to determine whether symbiotic micro-organisms called arbuscular mycorrhizal fungi can be used as a biocontrol method to protect sunflower against Orobanche cumana. We first observed that mycorrhization of sunflower plants reduced significantly their infection by Orobanche cumana. We then showed that mycorrhizal sunflower root exudates induced lower Orobanche cumana seed germination than non-mycorrhizal root exudates. Moreover, we demonstrated for the first time that AM fungi alone could produce inhibitors of Orobanche seed germination. Finally, we set up a novel in vitro system in which the early stages of sunflower root infestation by Orobanche cumana can be monitored. This system could be used to investigate possible effects of mycorrhizal fungi on these different stages

Abstract:
Orobanche cumana est une plante parasite obligatoire qui infecte spécifiquement le tournesol, entrainant des pertes de rendement. En combinant des études génétiques et génomiques dans une approche de clonage positionnel, le gène de résistance à l'orobanche du tournesol HaOr7 a été cartographié dans une région de 55 kb du chromosome 7, contenant un gène unique. Le gène HaOr7 code pour un récepteur membranaire de type LRR kinase, montrant de l'homologie avec le gène Xa21 qui confère la résistance à la bactérie Xanthomonas oryzae pv. Oryzae chez le riz. Toutes les lignées résistantes comportaient un allèle du gène codant pour la protéine HAOR7 complète tandis que les allèles du gène de toutes les lignées sensibles codaient pour une protéine tronquée, sans le domaine kinase, ni le domaine transmembranaire. Nous avons montré que HaOr7 confère une résistance en empêchant O. cumana de se connecter au système vasculaire des racines de tournesol, dans une relation gène-pour-gène. Nos résultats illustrent que les plantes utilisent des mécanismes de résistance contre les plantes parasites similaires à ceux qu'elles utilisent pour lutter contre les microorganismes pathogènes. HaOr7 est le premier gène de résistance à O. cumana à avoir été caractérisé chez le tournesol, ouvrant de nouvelles voies pour une résistance plus durable à O. cumana et aux plantes parasites
Orobanche cumana (sunflower broomrape) is an obligate parasitic plant that specifically infects sunflower roots, causing yield losses. By combining genomics and genetics in a map-based cloning strategy, we located the HaOr7 resistance gene to O. cumana in a 55 kb genomic region on chromosome 7 containing a single gene. The HaOr7 gene encodes a receptor-like LRR kinase protein sharing similarity with Xa21 in rice, conferring resistance to the bacteria Xanthomonas oryzae pv. oryzae. The complete HAOR7 protein was found in all resistant lines, while susceptible lines all encoded a truncated protein lacking the transmembrane and the kinase domains. We showed that HaOr7 confers resistance by preventing the connection of O. cumana to the vascular system of the sunflower roots in a gene-for-gene relationship. Our results illustrate how plants can use similar mechanisms for the resistance to parasitic plants as the ones for resistance to microorganisms. HaOr7 is the first resistance gene to O. cumana to be cloned in sunflower, opening new avenues for a more sustainable resistance to sunflower broomrape and to parasitic plants in crops

Abstract:
Seeds of the root parasitic plants of the genus Orobanche germinate specifically in response to host-derived germination signals, which enables parasites to detect and attack preferred hosts. The best characterized class of germination stimulants is the strigolactones (SLs), although some species respond to non-SL compounds, such as dehydrocostus lactone (DCL). Recent work indicates that SLs are perceived by members of the KARRIKIN-INSENSITIVE2 (KAI2) gene family, and suggests that within parasitic Orobanchaceae the KAI2 genes have undergone duplication and specialization. The "diverged" clade of these genes, termed KAI2d, has been shown to bind SL germination stimulants in model system assays, but the precise role for KAI2d in regulating germination specificity in a parasitic plant has not been demonstrated. To address this issue, we used genetic and genomic approaches involving two closely related species, Orobanche cernua and O. cumana, which differ primarily in host range and stimulant preference. Orobanche cernua parasitizes tomato (and other Solanaceous crops) and responds to orobanchol, the major SL from tomato roots, whereas O. cumana specifically parasitizes sunflower and responds to DCL. Crosses between O. cernua and O. cumana produced hybrid populations that segregate for stimulant specificity, creating a tractable genetic system. Orobanche cernua contains four KAI2d genes (numbered OrceKAI2d1-4), while O. cumana contains six genes (OrcuKAI2d1-6). The DNA from 94 F2 hybrids was genotyped to identify the KAI2d gene composition and these were correlated with germination phenotype. The pattern of segregation indicated that the KAI2d genes are linked, but pointed to OrceKAI2d2 as a likely orobanchol receptor. Response to DCL was associated with inheritance of all O. cumana KAI2d genes together. Each KAI2d gene was expressed in the Arabidopsis thaliana kai2 mutant background and tested for ability to recover the mutant phenotype when exposed to SLs (including orobanchol, 5-deoxystrigol and GR24) or DCL. One O. cernua gene, OrceKAI2d2, responded to all SLs, but not DCL in this system. No DCL-specific KAI2 genes were identified. In summary, we have identified the likely SL receptor in O. cernua, and show evidence that the DCL receptor is either not a KAI2d protein, or uses KAI2d in combination with other signaling pathway components.

Abstract:
Le criblage de nombreux Helianthus, sauvages, hybrides et lignées, a été effectué en serre afin de sélectionner des génotypes résistants à Orobanche cumana. Une étude plus approfondie de ces génotypes a montré que le génotype LR1 descendant du croisement d'un tournesol cultivé avec l'espèce sauvage H. Debilis debilis, induit des nécroses du parasite conduisant à une réduction drastique du nombre d'orobanches émergées. Le génotype 92B6 issu du croisement interspécifique avec l'espèce sauvage H. Argophyllus provoque lui aussi de nombreuses nécroses mais à des stades plus tardifs du développement de l'orobanche qui ne parvient toutefois pas à la floraison. Un système de culture hydroponique du couple tournesol / orobanche a permis d'étudier les réactions de défense chez le génotype résistant LRI. La réponse de ce génotype fait intervenir des épaississements de paroi, l'occlusion des vaisseaux du xylène et des divisions cellulaires au niveau du parenchyme cortical et du phloème. Ces réactions conduisent à une diminution de l'alimentation en eau et en nutriments du parasite. En effet, l'importation d'assimilats marqués au 14C dans les orobanches fixées sur les racines du génotype résistant LR1 est réduite par rapport à celle observée chez les orobanches se développant sur un tournesol sensible

Abstract:
La résistance du tournesol LR1 à l'infestation par la plante parasite Orobanche cumana est caractérisée par une surexpression du gène de défensine HaDef1. Les défensines sont de petits peptides basiques antifongiques d'une cinquantaine d'acides aminés. Chez le tournesol, trois gènes de défensines avaient été identifiés jusqu'à présent. Afin de mieux caractériser leur rôle dans la résistance à O. Cumana, une étude moléculaire de cette famille multigénique été entreprise. Ainsi, deux nouveaux gènes ont pu être identifiés et sur les cinq identifiés, trois sont exprimés dans les racines, dont HaDef1, et répondent différemment à des molécules activatrices des voies de défenses des plantes telles que le SA ou le JA. Par contre, seul le gène HaDef1 est très fortement surexprimé en réponse à l'infestation par O. Cumana. Une production du peptide correspondant HaDEF1 en système bactérien a permis d'étudier son activité. A des concentrations micromolaires, la défensine Ha-DEF1 provoque une mort cellulaire à l'apex de la radicule de graines germées d'O. Cumana et O. Ramosa alors qu'elle reste sans effet sur A. Thaliana et Striga hermonthica. Ha-DEF1 est fortement inhibée en présence d'ion calcium, de plus l'AAL toxine, une molécule perturbant la voie de biosynthèse des sphingolipides, provoque les mêmes symptômes que cette défensine. Enfin, Ha-DEF1 provoque une élévation de calcium intracellulaire en activant la voie de l'IP3. Ces résultats ont permis de mettre en évidence pour la première fois, une activité toxique de défensine de plante sur des cellules de plantes et ouvrent de nouvelles perspectives dans la compréhension du mode d'action des défensines
The resistance of the LR1 sunflower to the parasitic plant Orobanche cumana is chracaterized by an overexpression of the defensin gene HaDef1. Defensins are small basic antifungal peptides of around 50 amino acids. To date, three genes had been identified in the sunflower. In order to better understand the defensin role in sunflower resistance to O. Cumana, a molecular study was conducted on this small multigenic family. Thus, two new genes were identified and among the five identified, three of them including HaDef1 are expressed in roots but response differently to defence activating molecules like SA or JA. On the other hand, only HaDef1 is highly overexpressed after O. Cumana infestation. A peptide production in an heterologous bacterial system was conducted to study the Ha-DEF1 activity. At micromolar concentrations, Ha-DEF1 induces cell death at the radicle apex of germinated seeds of O. Cumana or O. Ramosa, but has no effect on A. Thaliana or the parasitic plant Striga hermonthica. Ha-DEF1 is strongly inhibited by calcium addition and AAL toxin, a sphingolipid metabolism disruptant, provokes the same symptoms as this defensin. Ha-DEF1 triggers also an intracellular calcium increase by activating the IP3 pathway in orobanche cells which could explain cell death. Theses results highlight for the first time a toxic activity of plant defensins on plant cells and open up new perspectives in the comprehension. Of its mode of action

Abstract:
L'orobanche, orobanche cumana, est une angiosperme, parasite des racines du tournesol (helianthus annuus l. ). Originaire du bassin mediterraneen, elle cause d'importants degats dans les pays producteurs excepte en france. Cinq races d'orobanche ont ete caracterisees dans les pays de l'est (elle est observee en russie des le debut du siecle) et 4 en espagne (ou elle est apparue en 1958). Ces races seraient controlees par des genes notes or. Mais l'etude de la genetique de la resistance n'est pas encore bien comprise. La capacite du pathogene a surmonter les resistances et sa facilite de dissemination en font un parasite difficile a maitriser. La lutte privilegiee passe par l'utilisation de resistances naturelles. L'objectif de ce travail est d'une part d'etudier la variabilite au niveau moleculaire et au niveau de la virulence de populations d'orobanches pour voir leur evolution et d'etudier la genetique de la resistance avec ces populations caracterisees. Huit populations d'orobanches (3 bulgares, 1 roumaine, 1 turque et 3 espagnoles) ont ete caracterisees par rapd et par aflp pour deux d'entre elles. Une population bulgare et deux populations espagnoles ont ete utilisees pour les tests de resistance sur les familles f 3 de deux croisements. L'adn des f 2 a servit au marquage moleculaire (marqueurs rflp et scar) pour localiser des genes de resistance sur la carte du tournesol par la technique des bulks et par la recherche de qtl. Une faible variabilite moleculaire intra- et inter-populations a ete trouvee (rapd et aflp apportant la meme precision). Les populations sont structurees en fonction de leur origine geographique et de leur virulence. Les populations espagnoles sont probablement issues des pays de l'est. La variabilite existant entre les populations d'orobanche pourra etre utilisee pour caracteriser les races existantes. Trois genes majeurs de resistance ainsi qu'or5 ont ete localises sur le groupe de liaison 16 de la carte genetique du tournesol. Le niveau de resistance semble dependre du genotype de tournesol et de la population d'orobanche utilises. Enfin, il apparait que la mise en place d'un differentiel sur pour caracteriser les races est necessaire aussi bien pour l'etude de la genetique que pour suivre l'evolution des races.

Abstract:
In this study, the effectiveness of different types of molecular markers in assessing genetic diversity of populations of O. cumana from China was determined. ISSR and SSR markers detected different levels of genetic variability among and within broomrape populations. SSR markers analysis showed high level of genetic variation within the populations as revealed by high average values of Nei's gene diversity (H=0,75) and Shannon's information index (I=1,44), while genotyping with ISSR markers showed greater ability to discriminate genotypes according to Resolving power (Rp=7,24). Thus, the combined use of ISSR and SSR markers allowed the detection of higher polymorphism than either set of marker alone.

Full text
Abstract:
Oroginal Objectives: (i) identify DNA markers linked to the avirulence (Avr) locus and locate the Avr locus through genetic mapping with an inter-race Orobanche cumana population; (ii) develop high-throughput fingerprint DNA markers for genotypingO. cumana races; (iii) identify nucleotide binding domain leucine rich repeat (NB-LRR) genes encoding R proteins conferring resistance to O. cumana in sunflower; (iv) increase the resolution of the chromosomal segment harboring Or₅ and related R genes through genetic and physical mapping in previously and newly developed mapping populations of sunflower; and (v) develop high-throughput DNA markers for rapidly and efficiently identifying and transferring sunflower R genes through marker-assisted selection. Revisions made during the course of project: Following changes in O. cumana race distribution in Israel, the newly arrived virulent race H was chosen for further analysis. HA412-HO, which was primarily chosen as a susceptible sunflower cultivar, was more resistant to the new parasite populations than var. Shemesh, thus we shifted sunflower research into analyzing the resistance of HA412-HO. We exceeded the deliverables for Objectives #3-5 by securing funding for complete physical and high-density genetic mapping of the sunflower genome, in addition to producing a complete draft sequence of the sunflower genome. We discovered limited diversity between the parents of the O. cumana population developed for the mapping study. Hence, the developed DNA marker resources were insufficient to support genetic map construction. This objective was beyond the scale and scope of the funding. This objective is challenging enough to be the entire focus of follow up studies. Background to the topic: O. cumana, an obligate parasitic weed, is one of the most economically important and damaging diseases of sunflower, causes significant yield losses in susceptible genotypes, and threatens production in Israel and many other countries. Breeding for resistance has been crucial for protecting sunflower from O. cumana, and problematic because new races of the pathogen continually emerge, necessitating discovery and deployment of new R genes. The process is challenging because of the uncertainty in identifying races in a genetically diverse parasite. Major conclusions, solutions, achievements: We developed a small collection of SSR markers for genetic mapping in O. cumana and completed a diversity study to lay the ground for objective #1. Because DNA sequencing and SNPgenotyping technology dramatically advanced during the course of the study, we recommend shifting future work to SNP discovery and mapping using array-based approaches, instead of SSR markers. We completed a pilot study using a 96-SNP array, but it was not large enough to support genetic mapping in O.cumana. The development of further SNPs was beyond the scope of the grant. However, the collection of SSR markers was ideal for genetic diversity analysis, which indicated that O. cumanapopulations in Israel considerably differ frompopulations in other Mediterranean countries. We supplied physical and genetic mapping resources for identifying R-genes in sunflower responsible for resistance to O. cumana. Several thousand mapped SNP markers and a complete draft of the sunflower genome sequence are powerful tools for identifying additional candidate genes and understanding the genomic architecture of O. cumana-resistanceanddisease-resistance genes. Implications: The OrobancheSSR markers have utility in sunflower breeding and genetics programs, as well as a tool for understanding the heterogeneity of races in the field and for geographically mapping of pathotypes.The segregating populations of both Orobanche and sunflower hybrids are now available for QTL analyses.

Identifying the genes involved in host root perception by root parasitic weeds: Genetic and transcriptomic analysis of Orobanche hybrids differing in signal response specificity. United States Department of Agriculture, January 2013. http://dx.doi.org/10.32747/2013.7598145.bard.

Full text
Abstract:
Seeds of the root parasitic plants of the genus Orobanchegerminate specifically in response to host-derived germination signals, which enables parasites to detect and attack preferred hosts. The best characterized class of germination stimulants is the strigolactones (SL), although some species respond to sesquiterpene lactones such as dehydrocostuslactone (DCL). Despite great progress in characterizing the SL signaling system in plants, the mechanism(s) by which parasite species detect specific compounds remains poorly understood. The goal of our project was to identify and characterize the genes responsible for stimulant specificity in O. cernuaand O. cumana. These two species are closely related, but differ in host range, with O. cernuaparasitizingSolanaceous crops such as tomato (and responding to SLs), and O. cumanaspecifically parasitizing sunflower (and responding to DCL). We used a genetic approach based on O. cernuax O. cumanahybrids to associate germination response with genes. We found that these parasite species each have multiple copies of KAI2d genes, which function in SL perception. In O. cernua, the OrceKAI2d2 responds to SL stimulants and is most consistently associated with hybrid lines that respond to SLs. For O. cumana, an apparently linked block of KAI2d genes was associated with response to DCL in hybrid lines, but we found no strong evidence that any of the OrcuKAI2d genes specifically recognize the DCL stimulant. Remarkably, one O. cumanagene, OrcuKAI2d5, responds to certain SLs in a genetic complementation assay, even though hybrid lines containing this gene show fidelity to DCL. In summary, we have identified the SL receptor in O. cernua, but the DCL receptor in O. cumanaremains unknown. Our data point to involvement of additional genes and yet greater levels of complexity regulating germination specificity in Orobanche. BARD Report - Project 4616 Page 2 of 8

Abstract:
En la presente nota de clase correspondiente al curso del programa de Ingeniería Civil, Electiva Específica I, cuya denominación es “Hábitat Sustentable y Eficiencia Energética” del noveno semestre, se abordan las problemáticas ambientales y sociales relacionadas con las edificaciones destinadas a proyectos de vivienda no VIS, VIS y VIP, en el contexto de la ciudad de Villavicencio, Meta. Para ello, se inicia con la elaboración de una conceptualización de “edificación” en términos de la Ley 400 de 1997, seguida de la aplicación de medidas pasivas conforme a la Resolución 1025 del 2021 y la Resolución 549 del 2015. En estas normativas se establecen tanto las medidas activas como las medidas pasivas destinadas al ahorro y consumo eficiente del agua y la energía. Esta fundamentación es esencial para el futuro profesional en Ingeniería Civil, permitiéndole construir edificaciones que sean amigables con el entorno y saludables para sus ocupantes. La nota de clase proporciona al estudiante una metodología clara para evaluar edificaciones desde el diseño hasta la construcción y el posterior mantenimiento, asegurando que cumplan con los criterios de construcción sostenible. El objetivo es promover edificaciones en armonía con el medio ambiente y que contribuyan al bienestar de quienes las ocupan. Como actividad de aprendizaje, los estudiantes diseñarán y modelarán una edificación sostenible, en una determinada ciudad de la geográfica colombiana, aplicando la metodología que propone la nota de clase. Esta actividad busca que los estudiantes obtengan como resultado una edificación que cumpla con los principios de sostenibilidad establecidos.
