| Outline of Final Research Achievements |
Groupers of the genus Epinephelus are one of the most important aquaculture species in the world. Due to the economical and biological importance of groupers, physiological and endocrinological data are eagerly needed for improvement aquaculture. However, the endocrinological mechanism of sex change is not clearly understood. In this research, we focused on the pituitary. First, we had carried out RNA-seq by using grouper pituitary. Based on the data, we successfully isolated several genes of hormones. Second, we quantified hormone gene expressions during sex change in grouper. Finally, we has been identified that key regulatory factor underlying sex change is FSH.
