| Outline of Final Research Achievements |
The Oligochaete Enchytraeus japonensis was found as potworm to aggrandize the first time asexual reproduction in Japan, depending on the growth environment, it has a feature that can be switched sexual or asexual reproduction. Fragments of autotomy the earthworm in the asexual reproduction are, and gonads differentiate keep in sexual-inducing conditions. Although the involvement of neoblast that were placed in the regeneration process of asexual reproduction has been suggested is considered a different mechanism than neoblast in sexual reproduction.
Genetic information for Enchytraeus japonensis is very poor, not sufficient to explain the two life cycles. In this study, we created a complementary DNA cells was induced sexual into the material, it performs a de novo RNA sequencing. We attempted to identify genes associated with sexual differentiation.
