Изучен конститутивный уровень экспрессии генов, кодирующих PR-белки: тауматин-подобный белок (Tlp) и оксалатоксидазу (OxOxid) в проростках 20 коллекционных сортов озимой пшеницы с разной устойчивостью к мучнистой росе. Показано, что растения с повышенной устойчивостью к мучнистой росе имеют высокий уровень экспрессии гена Tlp и низкий уровень экспрессии гена OxOxid, либо высокий уровень экспрессии гена OxOxid и низкий уровень экспрессии гена Tlp соответственно. Предлагается использовать показатель «уровень экспрессии генов Tlp и OxOxid» для скрининга селекционного материала озимой пшеницы с целью выявления генотипов с повышенной устойчивостью к мучнистой росе. 

In the present article, we studied a correlation between an increased resistance of winter wheat seedlings of different varieties to powdery mildew and high levels of constitutive expression of genes encoding one of two pathogenesisrelated proteins: thaumatin-like protein (Tlp) or oxalate oxidase (OxOxid). Highly resistant varieties have shown either high Tlp expression and low OxOxid expression or high OxOxid expression and low Tlp expression. We propose to use a combination of both Tlp and OxOxid gene expression levels as a marker for resistance of winter wheat breeding material to powdery mildew.
