Book Synopsis Genetic and virulence diversity of Puccinia graminis f. sp. Tritici populations in Ethiopia and stem rust resistance genes in wheat by : Belayneh Admassu Yimer
Download or read book Genetic and virulence diversity of Puccinia graminis f. sp. Tritici populations in Ethiopia and stem rust resistance genes in wheat written by Belayneh Admassu Yimer and published by Cuvillier Verlag. This book was released on 2010-03-23 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of a recent spread of a new and highly virulent race of Puccinia graminis f. sp. tritici called Ug99, stem rust is becoming a serious threat to wheat production in Ethiopia and other east African countries. Therefore, there is an urgent need to analyse the virulence spectrum of Pgt populations in Ethiopia. Wheat stem rust samples were collected in 2006 and 2007 in Arsi, Bale, Shewa and the Northwest regions of Ethiopia to determine the virulence diversity and race distribution in P. graminis f. sp. tritici populations. Stem rust incidence was high in Arsi, Bale and East Shewa. In Northwest Ethiopia, and North and West Shewa, stem rust was prevalent at low levels. A total of 152 isolates was analyzed and 22 races were identified. Races TTKSR (Ug99), TTHSR and RRTTR were predominant with frequencies of 26.6, 17.7 and 11.1%, respectively. These races were also detected in all regions. It turned out that the highly virulent race designated as Ug99 was present throughout the country and dominated in all regions except Northwest Ethiopia. A variant of Ug99, which is virulent against Sr24 was not detected in this study. Four stem rust resistance genes (Sr13, Sr30, Sr36 and SrTmp) were found to confer resistance to most of the races prevalent in Ethiopia. With the exception of Sr30, which is not effective to Ug99, the other three genes can be used in breeding for resistance to stem rust in Ethiopia.

Book Synopsis Management of Wheat and Barley Diseases by : Devendra Pal Singh
Download or read book Management of Wheat and Barley Diseases written by Devendra Pal Singh and published by CRC Press. This book was released on 2017-10-12 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both wheat and barley are two of the most important food and industrial crops in the world. Wheat and barley cultivation has experienced changes in practices due to factors such as methods of conservation agriculture, cropping systems, wheat varieties, changes in weather patterns, and international trade, necessitating new and different approaches for the successful management of emerging diseases and new pathotypes of pathogens. This valuable volume explores a multitude of new approaches and techniques for the effective management of emerging wheat diseases. This new volume presents the latest literature on management technology of diseases that affect the production of wheat and are capable of reducing grain yields as well as grain quality. These diseases include rusts, smuts, other foliar diseases such as blight, spots, blotch, powdery mildew, bunts, etc., as well as diseases such as Karnal bunt of wheat, which is of importance to international trade. This book will be highly valuable to researchers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat and barley. It also advances our knowledge in the field of plant pathology, plant breeding, and plant biotechnology, agronomy, and grain quality and pesticide industries. The book will serve as a reference on disease management technologies for the containment of losses in wheat and barley yields and will assist in maintaining wheat quality, reducing the cost of cultivation, increasing yield, and thus in helping to ensuring food security on a global level.
Book Synopsis Genomics of Plant-Associated Fungi: Monocot Pathogens by : Ralph A. Dean
Download or read book Genomics of Plant-Associated Fungi: Monocot Pathogens written by Ralph A. Dean and published by Springer. This book was released on 2014-08-23 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how genomics has revolutionized our understanding of agriculturally important plant-associated fungi. It illustrates some fundamental discoveries about these eukaryotic microbes with regard to the overall structure of their genomes, their lifestyles and the molecular mechanisms that form the basis of their interactions with plants. Genomics has provided new insights into fungal lifestyles and led to practical advances in plant breeding and crop protection, such as predictions about the spread and evolution of new pathogens. This volume focuses on fungi that are important cereal and other monocot plant pathogens and includes: Pyrenophora tritici-repentis, Cochliobolus sp., Colletotrichum sp., Fusarium graminearum, Mycosphaerella graminicola and Mycosphaerella fijiensis, Magnaporthe oryzae, Blumeria graminis and Puccinia graminis.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stem rust caused by the biotrophic fungal pathogen Puccinia graminis f. sp. tritici (Pgt) is an important disease of barley and wheat globally. In the last decade, the Pacific Northwest (PNW) region of the United States has experienced an increase in the incidence and severity of stem rust disease. This may be attributed to various factors, including increase in summer temperatures, lack of effective resistance, and early inoculum from sexual hosts. The PNW region's conducive environment and the presence of the sexual hosts, Mahonia and barberry, present an opportunity for the stem rust pathogen to complete its sexual cycle, leading to the emergence of genotypes with novel virulence gene combinations. A total of 100 Pgt isolates collected from barley in eastern Washington during the 2019 growing season were tested for virulence on the two major barley stem rust resistance genes/loci, Rpg1 and the rpg4/5-mediated resistance locus (RMRL) at the seedling stage. Of these isolates, 99% were virulent on cultivar Morex containing the Rpg1 gene, 62% were virulent on Golden Promise transgenic line (H228.2c) carrying a single copy of the Rpg1 gene from Morex, 16% were virulent on the near isogenic line, HQ-1 containing RMRL, and 10% were virulent on barley line Q21861 carrying both Rpg1 and RMRL. This was the first report of Pgt isolates containing virulence on both Rpg1 and RMRL when stacked together, representing the most virulent Pgt population reported on barley worldwide. To identify and map effective resistances against the local virulent isolates, a genome wide association study (GWAS) was conducted on 440 accessions from the World Barley Core Collection (WBCC), genotyped with the 9K Illumina barley iSelect chip and phenotyped with two PNW Pgt isolates at the seedling stage. A total of 10 resistance loci were identified including four novel loci on chromosomes 1H, 2H, 5H, and 6H. On the pathogen side, GWAS was performed using 113 diverse Pgt isolates, collected from the PNW and the Midwest region of the US, to identify virulence and avirulence loci corresponding to the barley stem rust resistance gene Rpg1 and the six wheat stem rust R-genes, Sr5, Sr21, Sr8a, Sr17, Sr9a, and Sr9d. The genotype data for 96 isolates were generated by whole genome shotgun sequencing and for 17 isolates by RNA sequencing. The phenotype data for the Pgt isolates were collected by seedling disease assays on two barley lines, H228.2c and Morex (Rpg1+) and the six wheat stem rust differential lines, Sr5, Sr21, Sr8a, Sr17, Sr9a, and Sr9d. A total of five effector gene candidates were identified at two loci corresponding to the Rpg1 gene. Similarly, 24 putative effector genes were identified at 15 loci corresponding to the six wheat R-genes. Further characterization of these genes will be done to enhance our understanding of host pathogen interactions in both the barley-Pgt and wheat-Pgt pathosystems.
