Outline of Final Research Achievements

We investigated that defense of the liverwort, Marchantia polymorpha, against herbivores. We showed that the liverwort had ability to repel and to reduce survival, reproduction, development and hutching of herbivores, two-spotted spider mite and common cutworm. We also showed that the liverwort which cannot make 12-Oxo-phytodienoic acid (OPDA) that is an intermediate in jasmonic acid biosynthesis did not significantly reduce survival of two-spotted spider mite females. The amount of jasmonic acid and salicylic acid in the liverwort tended to increase with feeding damage by herbivores. These results suggested that the liverwort might have induction defense against herbivores.
