In search of the relationship between the rye polyamine oxidase (PAO) gene and resistance to powdery mildew (PM).

ABSTRACT: Powdery mildew (PM), a common cereal disease in cultivated areas, including Europe and other temperate regions, is caused by the fungus Blumeria graminis. While PM is one of the most important wheat leaf diseases globally, rye is highly tolerant to PM. It has been reported that in barley infected with PM, polyamine oxidase (PAO) activity related to the production of hydrogen peroxide (H₂O₂) has increased, which may promote defense against biotrophic or hemibiotrophic pathogens. The current study aimed to assess the relationship between the segregation of the polymorphic marker for rye PAO (ScPAO) and the level of PM infection in plants. The genetic mapping in two interline populations shows that ScPAO is located on chromosome 7R. Further analysis comparing ScPAO locat
