Using real-time PCR analysis, the constitutive expression of PR-protein genes encoding thaumatin-like protein ( TLP ), peroxidase III ( TaPero ), chitinase ( Chitin ), glucanase ( Glucan ), protease inhibitor ( PrInh ), oxalate oxidase ( OxOxid ) and lipid transfer protein ( Ltp ) was studied in collection varieties of winter wheat. It has been shown that plants of varieties with increased resistance to a complex of leaf pathogens have higher constitutive expression levels of Chitin and PrInh genes, and, to a greater extent, of TLP , TaPero and Glucan genes, compared with non-resistant varieties. It is proposed to use constitutive levels of expression of TLP , TaPero and Glucan genes for the selection of winter wheat varietal samples with increased resistance to the complex of leaf diseases.
