Role of Sox3 in Estradiol-Induced Sex Reversal in Pelodiscus sinensis.

ABSTRACT: The Chinese soft-shelled turtle Pelodiscus sinensis, an economically important species in China, exhibits significant sexual dimorphism. Males are more valuable than females owing to their wider calipash and faster growth. Estradiol (E2)-induced sex reversal is used to achieve all-male breeding of turtles; however, the mechanism of this sex reversal remains unclear. In this study, we characterized the Sox3 gene, whose expression level was high in the gonads and brain and exhibited significant sexual dimorphism in the ovary. During embryonic development, Sox3 was highly expressed at the initiation of ovarian differentiation. E2 and Sox3-RNAi treatment before sexual differentiation led to 1352, 908, 990, 1011, and 975 differentially expressed genes in five develop
