| Outline of Final Research Achievements |
The sex differentiation cascade of Oryzias sakaizumii is very similar to that of Nile tilapia, a useful fisheries species for aquaculture, unlike O. latipes. This study is conducting research using this species as a new model by comparing it to sex differentiation and masculinization in tilapia and masculinization in Grouper. In this study, we examined the molecular mechanisms of gonadal differentiation and sex change from sex determination. Thus we demonstrate the existence of an unknown testis differentiation pathway as the primary pathway for sex transdifferentiation to the testis.
