Professor Yasuyuki Kubo, Assistant Professor Sayo Kodama, Faculty of Agriculture, Setsunan University, University of Marseille, France, Research Center for Disease Models, Kanazawa University, and other research groups are working to clarify the infection mechanism of anthracnose fungus, which infects Cucurbitaceous plants and causes necrotic lesions. elucidated for the first time.
According to Setsunan University, an anthracnose fungus, a phytopathogenic fungus, invades plants by forming special cells called appressoria on the surface of plants and sticking needle-like hyphae into the plants. Attempts to infect by sending various proteins.
At this time, the research group discovered that the anthracnose fungus secreted two oxidases, alcohol oxidase and peroxidase, from the appressorium, and that the two oxidases paired to produce long-chain aldehydes from long-chain alcohols on the surface of the plant. discovered.
A total gene expression analysis of the anthracnose fungus during the infection process revealed that the production of long-chain aldehydes induces the expression of genes related to the pathogenicity of the anthracnose fungus.
These oxidase pairs are specific to plant pathogens.The research group expects that the results of this research will lead to the development of new control agents that inhibit the expression of pathogenicity mediated by oxidases.
