The suppression of disease onset was examined using wheat, the fusarium pathogen, and DON-degrading bacterial strain SS3 or its mutants with reduced DON metabolic capacity. In the USU-Apogee variety (weakly resistant to fusarium head blight), the suppressive effect of the mutant strain was significantly lower than that of the wild strain, indicating that the suppressive effect of the mutant strain was reduced due to defective DON degradation. On the other hand, no significant difference in suppression was observed between the mutant and the wild strain in the same test using the variety No. 61 (moderately resistant to fusarium head blight), indicating that one of the mechanisms of suppression of fusarium head blight onset by the SS3 strain is DON-degrading metabolism. However, the degree of contribution of DON-degrading bacteria to the suppressive effect of DON-degrading and metabolizing bacteria on wheat varied among wheat cultivars.

As cold-sensitive insects expand their habitat due to climate change, phytoplasma-related diseases in the tropics and subtropics transmitted by these insects are expected to move northward, and there is concern that rice orange leaf phytoplasma (ROLP), which occurs in Southeast Asian countries, may invade Japan. In this study, we investigated the ROL disease occurrence and ROLP genotypes in Southeast Asian countries, and we found that ROLP originated in Thailand and neighboring countries and that only a particular ROLP genotype is expanding to near East Asia, probably by the contributions of newly identified insect vectors such as a green leafhopper in addition to previously reported insects. In addition, the behavior of the pathogen in plants and some physiological changes in affected plants were clarified, and important findings were obtained for disease control.

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.
