Wheat gene Yr39 confers durable high-temperature adult-plant (HTAP) resistance to stripe rust caused by Puccinia striiformis f. sp. tritici, one of the most destructive diseases wheat worldwide. The objective this study was transfer into four Chinese elite cultivars. Backcross inbred line populations were developed from cultivars Chuanmai 42 (CM42), Bainong Aikang 58 (AK58), Han 6172 (H6172) an...

Stripe rust [caused by Puccinia striiformis Westend. f. sp. tritici Eriks. (Pst)] is a destructive disease of wheat (Triticum aestivum L.) worldwide. Genetic resistance is the preferred method for control and the Yr5 gene, originally identified in Triticum spelta var. album, represents a major resistance (R) gene that confers all-stage resistance to all currently known races of Pst in the Unite...

Puccinia striiformis f. sp. tritici (Pst) is an obligate biotrophic fungus that causes the destructive wheat stripe rust disease worldwide. Due to the lack of reliable transformation and gene disruption method, knowledge about the function of Pst genes involved in pathogenesis is limited. Mitogen-activated protein kinase (MAPK) genes have been shown in a number of plant pathogenic fungi to play...

Rice (Oryza sativa L.) is the only widely cultivated gramineous crops that cannot be infected by rust fungi. To decipher the molecular basis of rice nonhost resistance (NHR) to Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust, proteomic analysis was performed using the two-dimensional electrophoresis (2-DE) technique. The expressed proteins from rice leaves 24 an...

El presente estudio se llevó a cabo con el propósito de evaluar pérdidas rendimiento grano trigo ocasionadas por roya lineal amarilla (Puccinia striiformis f. sp. tritici) y valorar la efectividad selección masal visual recurrente para generar genotipos alto resistentes amarilla. Se evaluaron los ciclos C0 C7 generados mediante metodología MSFRS (Male Sterile Facilited Recurrent Selection), alt...

Stripe rust (Puccinia striiformis f. sp. tritici (Pst)) is one of the most devastating fungal diseases durum wheat (Triticum turgidum L. var. Desf.). Races Pst with new virulence combinations are emerging more regularly on wheat-growing continents, which challenges breeding for resistance. This study aimed to identify and characterize resistance races based a genome-wide association study. GWAS...
