PR-proteins as markers of winter wheat (Triticum aestivum L.) resistance to leaf pathogens

Full Text:


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 TLPTaPero and Glucan genes, compared with non-resistant varieties. It is proposed to use constitutive levels of expression of TLPTaPero and Glucan genes for the selection of winter wheat varietal samples with increased resistance to the complex of leaf diseases.
