Abstract
Pyrenophora graminea is a seed-borne pathogen and the causal agent of the barley leaf stripe disease. Our aim is to study the genetic basis of barley resistance to leaf stripe. A qualitatively acting resistance factor has been identified in the cultivar 'Vada' and the partial resistance of the cultivar 'Proctor' to a P. graminea isolate have been demonstrated to be dominated by a major quantitative trait locus (QTL), mapped on barley chromosome 1. Map colinearity between the leaf stripe 'Proctor' resistance QTLs, 'Vada' resistance to leaf stripe and other disease resistance loci have been investigated in this work using molecular markers. Moreover, since inoculation of barley rootlets by the fungus had been shown to induce the accumulation of several PR (pathogen-related) mRNA families, seven barley PR genes have been mapped as RFLPs, and one assigned to a chromosome arm via ditelosomic analysis to verify possible map associations between the known leaf stripe resistance loci, resistance loci towards other seed-borne pathogens and defense gene loci.
