Abstract:: ... Stem rust, caused by Puccinia graminis, and crown rust, caused by P. coronata, are common rust diseases on cool-season grasses (Karakkat et al. 2018), for which long-distance spore dispersal was recorded in northern United States (Harder and Haber 1992). During the summers of 2019 and 2020, severe infection of stem rust and crown rust was observed on >60% of tall fescue (Festuca arundinacea) germp ...

Abstract:: ... The resistance gene Sr13 is one of the most important genes in durum wheat for controlling stem rust caused by Puccinia graminis f. sp. tritici (Pgt). The Sr13 functional gene CNL13 has haplotypes R1, R2 and R3. The R1/R3 and R2 haplotypes were originally designated as alleles Sr13a and Sr13b, respectively. To detect additional Sr13 alleles, we developed Kompetitive allele specific PCR (KASP™) mar ...

The international letter-code system of nomenclature has been used to pathotype these new emerging races, and gene SrMcN from ‘McNair 701' winter wheat, which is one of the differential lines, was ex ...

There are nine NPR1 homologues (TaNPR1) in wheat, but little research has been done to understand the function of those NPR1‐like genes in the wheat defence response against stem rust (Puccinia graminis f. sp. tritici) pathogens. We used bioinformatics and reverse genetics approaches to study the expression ...

Abstract:: ... Wheat rust can cause catastrophic crop failures. The Green Revolution succeeded in part thanks to the deployment of wheat with genetic resistance to stem rust. The appearance of a new strain of stem rust in Uganda (Ug99), first detected in 1998, raised the threat of global stem rust epidemics beyond its prevalence in Africa and the Middle East. Despite over twenty years of awareness campaigns, res ...
