Abstract

Red spotted grouper, , is a popular aquaculture species and a protogynous hermaphrodite. Induction of artificial sex change at the time of primary sex differentiation is of interest but has not been successful due to the lack of necessary basic information. To find out the potential neuroendocrine influence on the primary sex differentiation, the expression of key genes in the brain was investigated during the formation of ovarian cavity. Expression of , , , , and in the brain was positively associated with the formation of ovarian cavity, showing gradual increase as the formation proceeds. However, the expression of was suppressed during the early part of the ovarian cavity formation, signifying potential hypothalamic influence on the primary sex differentiation in this species.

摘要

红斑石斑鱼是一种受欢迎的水产养殖品种，是一种雌性先熟的雌雄同体鱼类。在初级性别分化时诱导人工性逆转很有意义，但由于缺乏必要的基础信息尚未成功。为了探究潜在的神经内分泌对初级性别分化的影响，在卵巢腔形成过程中研究了大脑中关键基因的表达。大脑中、、、、和的表达与卵巢腔的形成呈正相关，随着形成过程逐渐增加。然而，在卵巢腔形成的早期阶段表达受到抑制，这表明该物种下丘脑对初级性别分化可能存在影响。
