| Outline of Final Research Achievements |
We found the appropriate conditions for germination, adhesion, and appressorium formation of Pyricularia oryzae, the rice blast fungus, on tomato leaves. We also establish the conditions of high-depth LED-UV irradiation to be >99.9% lethal, and P. oryzae was subjected to induce mutation by LED-UV irradiation under the conditions. Non-or weakly pathogenic mutant strain has not be obtained yet. We constructed a transformation vector for continuous expression of a secreted avirulence gene, SIX4, of tomato wilt fungus. The blast fungus was transformed using this vector, and we successfully obtained the SIX4-introduced transformants. Pretreatment of tomato with the SIX4-introduce transformant significantly inhibited the wilt disease in tomato caused by Fusarium oxysporum. This shows the possibility of blast fungus can be used as "bio microsyringe."
