Genetics of resistance to race TTKSK of Puccinia graminis f. sp. tritici in Triticum monococcum.
Race TTKSK (or Ug99) of Puccinia graminis f. sp. tritici possesses virulence to several stem rust resistance genes commonly present in wheat cultivars grown worldwide. New variants detected in the race TTKSK lineage further broadened the virulence spectrum. The identification of sources of genetic resistance to race TTKSK and its relatives is necessary to enable the development and deployment o...
متن کاملChanging the Game: Using Integrative Genomics to Probe Virulence Mechanisms of the Stem Rust Pathogen Puccinia graminis f. sp. tritici
The recent resurgence of wheat stem rust caused by new virulent races of Puccinia graminis f. sp. tritici (Pgt) poses a threat to food security. These concerns have catalyzed an extensive global effort toward controlling this disease. Substantial research and breeding programs target the identification and introduction of new stem rust resistance (Sr) genes in cultivars for genetic protection a...

stem rust caused by puccinia graminis f. sp. tritici (pgt) is one of the destructive diseases of wheat in the world. the fungal pathogen can infect 365 different grass and more than 70 berberis species. dna sequences for the ribosomal rna internal transcribed spacer (its) have proven suitable to explore relationships at the species and subspecies levels. an isolate of pgt which was collected fr...
متن کاملGenetic Mapping of Stem Rust Resistance to Puccinia graminis f. sp. tritici Race TRTTF in the Canadian Wheat Cultivar Harvest.
Stem rust, caused by Puccinia graminis f. sp. tritici, is a destructive disease of wheat that can be controlled by deploying effective stem rust resistance (Sr) genes. Highly virulent races of P. graminis f. sp. tritici in Africa have been detected and characterized. These include race TRTTF and the Ug99 group of races such as TTKSK. Several Canadian and U.S. spring wheat cultivars, including t...
متن کاملفاکتورهای بیماری‌زایی جدایه‌های زنگ ساقه (Puccinia graminis f. sp. tritici) و شناسایی منابع مقاومت در ژنوتیپ‌های سینتتیک گندم سیمیت
Wheat stem rust caused by Puccinia graminis f. sp. tritici (Pgt) is one of the most important diseases of wheat, worldwide. New sources of resistance to stem rust could be found in synthetic hexaploid wheat (SHW) genotypes due to their high genetic diversity. In order to recognize the genetic structure of the population of the stem rust, following race analysis of 12 Pgt isolates, resistance of...
