海马的特点是它的男性怀孕和性别角色逆转。为了更好地了解基于必需基因的雄性和雌性海马的性二态性，我们对两种性别进行了系统的转录组研究。获得总共157，834，590个清洁的读段并组装成129，268个转录物，并且31，764个可以被注释。结果表明，与雌性海马相比，雄性海马中有176个转录本上调，391个转录本下调。鉴定了与性别分化相关的基因dmrt1、sox9、fem1和vasa。此外，还对海马中参与生殖分子途径的必需基因进行了鉴定和分析。本研究为进一步系统研究海马性别分化提供了资料。
Seahorse is characterized by its male pregnancy and sex-role reversal. To better understand the sexual dimorphism of male and female seahorses based on essential genes, we performed systematic transcriptome studies for both genders. A total of 157,834,590 cleaned reads were obtained and assembled into 129,268 transcripts and 31,764 could be annotated. Results showed that 176 up-regulated and 391 down-regulated transcripts were identified in the male seahorses compared with those in females. Genes involved in sex differentiation, such asdmrt1, sox9, fem1andvasa, were identified and characterized. Moreover, the essential genes involved in reproductive molecular pathway were identified and analyzed in seahorses. In conclusion, the present study provides an archive for the future systematic research on seahorse sex differentiation.
