Outline of Final Research Achievements

In this study, we attempted to select candidate strains as biocontrol agents for Fusarium Head Blight and deoxynivalenol (DON) Accumulation. In order to conduct a convenience disease suppression test, we established a test method using germinating wheat and selected three strains that suppressed the disease development and DON accumulation.
To identify novel DON degrading and metabolizing enzymes, we created DON metabolizing mutant lines. 2000 mutant lines were examined for their DON metabolizing ability by optimizing the mutation conditions in UV treatment. As a result, we succeeded in obtaining about 20 strains that were deficient in DON metabolism. In the future, we will determine the mutation sites and the coding genes of the mutant strains.

Academic Significance and Societal Importance of the Research Achievements

本研究は作物上での、かび毒の蓄積と植物病害の発生の双方を抑制する微生物の選抜と機能解析を目指したものである。加えて、DONはかび毒であり病原性関連因子でもあるので、病原性関連因子を分解できる微生物の処理によって植物病原菌の病徴発現をも抑制が可能かを検証した研究でもある。本研究によって、病原性関連因子を分解する微生物が発病抑制に貢献しうることが明らかになった。
