“…Thus, in potato tubers of immune cultivar, infection with phytophthora also led to Н 2 О 2 accompanied by hypersensitivity response [25]. In resistant wheat plants infected with the causative agent of brown rust, there was detected intensive generation of ROS in stomata guard cells and leaf mesophyll, where inhibition contributed to the growth and development of pathogen in plant tissues [26]. Oxidases are known to make the greatest contribution to accumulation of Н 2 О 2 , oxalate oxidase being the pathogen-inducible protein and the most important component of pro-oxidant plant system [27].…”

Functional traits, potentially associated with resistance to infection, were investigated in cultivars of bread wheat. Plant responses to infection by hemibiotrophic fungus Stagonospora (Septoria) nodorum were studied under laboratory conditions. Infection-induced up-regulation of genes coding for class III peroxidase, oxalate oxidase and protease inhibitor was greater in leaves with reduced disease symptoms (percentage of chlorotic or necrotic leaf area). Similar association was detected between activity of pectinase inhibitors and disease severity. Resistant cultivar also differed from the susceptible one by increased content of Н2О2 in infected tissues and more intensive deposition of lignin. We discuss possibility of using these functional traits in plant breeding for increased stress tolerance.
