Association mapping with a diverse population of Puccinia graminis f. sp. tritici identified avirulence loci interacting with the barley Rpg1 stem rust resistance gene.

Background: Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is an important disease of barley and wheat.

High resolution mapping of a novel non-transgressive hybrid susceptibility locus in barley exploited by P. teres f. maculata.

Hybrid genotypes can provide significant yield gains over conventional inbred varieties due to heterosis or hybrid vigor. However, hybrids can also display unintended negative attributes or phenotypes such as extreme pathogen susceptibility. The necrotrophic pathogen Pyrenophora teres f.

Variability in Chromosome 1 of Select Moroccan f. Isolates Overcomes a Highly Effective Barley Chromosome 6H Source of Resistance.

Barley net form net blotch (NFNB) is a destructive foliar disease caused by f. Barley line CIho5791, which harbors the broadly effective chromosome 6H resistance gene , displays dominant resistance to f. .

Identification of Candidate Avirulence and Virulence Genes Corresponding to Stem Rust ( f. sp. ) Resistance Genes in Wheat.

Stem rust, caused by the biotrophic fungal pathogen f. sp. (), is an important disease of wheat.

Population and genome-wide association studies of isolates collected from diverse host plants throughout the United States.

Introduction: Sclerotinia sclerotiorum is a necrotrophic fungal pathogen causing disease and economic loss on numerous crop plants. This fungus has a broad host range and can infect over 400 plant species, including important oilseed crops such as soybean, canola, and sunflower. S.
