| Outline of Final Research Achievements |
We have been trying to elucidate the molecular mechanism of biosynthesis of plant hormones such as auxin and cytokinin, which are highly concentrated in gall-inducing sawfly. In this study, we identified the enzyme involved in auxin biosynthesis, which is present only in galling sawfly but not in non-gall-inducing silkworm. We have also identified an inhibitors of the enzyme.Further improvement of the inhibitor will pave the way to prove that IAA is essential for gall induction. Regarding cytokinin, there is no isopentenyl transferase in the sawfly genome, raising the possibility that the main pathway is via tRNA, which is different from what has been shown in plants.
