Race-specific resistance of wheat to Puccinia graminis f. sp. tritici is primarily posthaustorial and often involves the induction of a hypersensitive response (HR). The aim of this study was to investigate host defense responses induced in interactions between P. graminis f. sp. tritici races and wheat lines carrying different race-specific stem rust resistance (Sr) genes. In incompatible inte...

The Volga region is one of the main grain-producing regions Russia. Wheat stem rust caused by Puccinia graminis f. sp. tritici among most destructive fungal diseases wheat. Recently, its harmfulness has increased in region. In this regard, an analysis resistance and diversity Sr genes Russian wheat cultivars necessary. work, 126 (including 23 durum 103 bread cultivars) approved for use were eva...

pathogenicity of wheat stem rust was investigated during two cropping seasons of the years 2010 and 2011. towards this end, 47 isogenic lines of wheat stem rust along with 43 cultivars/lines of the crop were tested in field conditions (natural infection) and also in the greenhouse conditions. the results showed, similarity of pathogenicity for plants carring gene/s sr7b, sr8a, sr8b, sr9b, sr9d,...

Leaf or brown rust is one of the most devastating diseases in wheat. Development and deployment resistance wheat cultivars considered as effective, economic sustainable method protecting against yield losses due to leaf rust. Though several alien genes have been reported utilized, Thinopyron ponticum derived gene Lr24/Sr24 has proved be effective for nearly three decades India. The effectivenes...

Stem rust is a disease of wheat caused by basidiomycete Puccinia graminis f. sp. tritici (Pgt). Emergence new populations the pathogen and their spread over world calls for growing cultivars with lasting resistance. Knowledge resistance gene composition in local fields together knowledge global movements races crucial. Present study focused on using molecular markers to detect eight genes 58 en...

The damage to wheat crops by stem rust poses a threat the food security of world’s population. species Thinopyrum ponticum (Podpěra, 1902) (Z.-W. Liu and R.-C. Wang, 1993) is non-host for fungus Puccinia graminis f. sp. tritici Eriks. Henn. (Pgt). Sr24, Sr25, Sr26 genes, transferred from Th. gene pool, protect cultivars disease in different regions world. study resistance (NHR) effects introgre...
