Transcriptomic analysis of female and male gonads in juvenile snakeskin gourami (Trichopodus pectoralis).

ABSTRACT: The snakeskin gourami (Trichopodus pectoralis) exhibits sexual dimorphism, particularly in body size. Since the snakeskin gourami is usually marketed during sexual maturation, the sexual size dimorphism has become an economically important trait. Sex-biased gene expression plays a key role in phenotypic sexual dimorphism. Therefore, using high-throughput RNA sequencing (RNA-seq) technology, we aimed to explore the differentially expressed genes (DEGs) in ovary and testis during sex differentiation in juvenile snakeskin gourami. Our results revealed a number of DEGs were demonstrated to be overexpressed in ovary (11,625 unigenes) and testis (16,120 unigenes), and the top 10 female-biased (rdh7, dnajc25, ap1s3, zp4, polb, parp12, trim39, gucy2g, rtbs, and fdxr) and male-biased (vamp3, nbl1,
