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...
Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici (Pst), is a global concern for wheat production, and has been increasingly destructive in Ethiopia, as well as in the United States and in many other countries. As Ethiopia has a long history of stripe rust epidemics, its native wheat germplasm harbors potentially valuable resistance loci. Moreover, the Ethiopian germplasm has ...
Leymus mollis, a perennial allotetraploid (2n = 4x = 28), known as American dune grass, is a wild relative of wheat that could be useful for cultivar improvement. Shannong0096, developed from interspecific hybridization between common wheat cv. Yannong15 and L. mollis, was analyzed with cytological procedures, genomic in situ hybridization, stripe-rust resistance screening and molecular m...
Plant diseases often cause serious yield losses in agriculture. A pathogen’s reproductive fitness can be quantified by the basic reproductive number, R0. Since pathogen transmission between host plants depends on the spatial separation between them, R0 is strongly influenced by the spatial scales of pathogen dispersal and the spatial scales of the host population. We propose a novel method to e...
