简介：性决心和性区别是在鱼的重要现象，但是在Takifugu的性决心的机制磨擦ripes糟糕被理解。在我们在T的学习，为DMRT(DMRT1，DMRT2和DMRT3)的基因的表示模式，sox9a和sox9b。rubripestissues与反向的抄写(RT)-PCR察觉被验证。它在睾丸被看那DMRT1expressions，卵巢低得多，并且没有表情在肌肉，血和尾巴鳍被发现。然而，为DMRT2和DMRT3的表情没在上面说的纸巾被发现。sox9a的抄本在肌肉，鳍，卵巢和睾丸，然而并非在血被检测，而sox9bexpression仅仅在卵巢被检测。在T.rubripes性腺的DMRT，sox9a和sox9b的表示模式建议这些基因不能是性特定的。
