| Outline of Final Research Achievements |
This study includes three sub-themes described as follows. (1) Roles of signal transduction substances in defense system after inoculation of Raffaelea quercivora in oak-wilt disease were studied. The importance of the interaction of ethylene and methyl jasmonate in defense mechanism against R. quercivora infection in oak trees was studied. (2) Artificial control for the production of antibacterial substances in tree stems was studied. In sapwood of oaks, the enhancement of abnormal discoloration related to the production of antibacterial substances were promoted by the exogenous application of ethylene and methyl jasmonate. Those phenomena were similar to the development of vaccine effects. (3) The promotion of production technology for useful antibacterial substances in tree stems was studied. Roles of methyl jasmonate, ethylene or the interaction of both substances were studied in gummosis and resinosis of various woody species were studied.
