Mączniak prawdziwy powodowany przez grzyba Blumeria graminis f.sp. hordei (Bgh) należy do ważnych pod względem gospodarczym chorób jęczmienia. Dlatego realizowane są prace mające na celu określenia uwarunkowań odporności tego patogena odmian wprowadzonych Krajowego Rejestru genami specyficznymi jak i niespecyficznymi. W bieżących badaniach uwzględniono 52 odmiany jęczmienia jarego włączone Prog...

A wheat 660K chip was used to genotype two wheat-Dasypyrum villosum 6V#4S.6DL and 6V#2S.6AL translocation lines (A303 B303) their common recurrent parent Wan7107. The results showed that these three have similar characteristics of base composition except for the chromosomes. alien chromosomes fewer homozygous more heterozygous genotypes with invalid probes. Distributions SNPs between Wan7107 we...

Previously we reported that oxalate oxidase activity increases in extracts of barley (Hordeum vulgare) leaves in response to the powdery mildew fungus (Blumeria [syn. Erysiphe] graminis f.sp. hordei) and proposed this as a source of H2O2 during plant-pathogen interactions. In this paper we show that the N terminus of the major pathogen-response oxalate oxidase has a high degree of sequence iden...

Systemic acquired resistance (SAR) is one of the intriguing issues for studying the mechanism in signal transduction system in a whole plant. We found that SAR and increase of an antifungal compound were induced rapidly and transiently in barley (Hordeum vulgare L. cv. Goseshikoku) by mechanical and biological stresses. One of the major antifungal compounds was identified as an indole alkaloid,...

Race-non-specific, or quantitative, pathogen resistance is of high importance to plant breeders due to its expected durability. However, it is usually controlled by multiple quantitative trait loci (QTL) and therefore difficult to handle in practice. Knowing the genes that underlie race-non-specific resistance (NR) would allow its exploitation in a more targeted manner. Here, we performed an as...
