Abstract
Экспрессия генов лектина и дефенсина у сортов пшеницы Мироновская 808 и Roazon при инфицировании Pseudocercosporella herpotrichoides
Highlights
Plant-pathogen biochemical interactions under the infection process demonstrate complicated regulatory linkage between these two organisms
Since the active reactions to the attack of pathogenic agents are usually connected with the change in expression of genes, coding pathogen-induced proteins [10], the aim of this work was to study the dynamics of lectin and defensin genes expression in the formation of immune response of winter wheat cultivars (Triticum aestivum L.), differing in their level of resistance, which were affected by eyespot agent (P. herpotrichoides (Fron) Deighton) at early stages of ontogenesis
The dynamics of expression of lectin and defensin genes in seedlings of winter wheat cultivars, different in their level of resistance, which were infected with P. herpotrichoides, evidenced that the stress effect of phytopathogen changes the content and ratio of studied transcripts of antimicrobial substances, lectins and defensins, genes in plant tissues
Summary
Plant-pathogen biochemical interactions under the infection process demonstrate complicated regulatory linkage between these two organisms. The investigation of these interactions on the levels, ranging from the organism to a cell, testifies to the activation of different mechanisms of pathogen attack and plant defence, depending on the stage of development of the disease. Low-molecular proteins, are primary substances, responsible for the process of recognizing a foreign agent, its binding, prevention or slowing down the infection process. They participate in the formation of plant immunity as a primary link of elicitor-induced launch of plant cell signalling systems.
