The phenotypic sex of fish is usually plastic. Low-temperature treatment induces the masculinization of , resulting in pseudo-males (PM) with the physiological sex of a male (M) and genetic sex of a female (F). For a comparison of gonadal transcriptomes, we collected gonads from three groups of (F, M, and PM) for high-throughput transcriptome sequencing. The results provided 467,640,218 raw reads (70.15 Gb) and a total of 436,151,088 clean reads (65.43 Gb), with an average length of 150 bp. Only 79 differentially expressed genes (DEGs) were identified between F and PM, whereas 12,041 and 11,528 DEGs were identified between F and M, and PM and M, respectively. According to the functional annotation of DEGs, 13 DEGs related to gonadal development were screened (, , , , , , , , , , , , and ) which might participate in formating PM. A quantitative PCR of the DEGs confirmed the reliability of the RNA-seq. Our results provide an important contribution to the genome sequence resources for and insight into the molecular mechanism of masculinization in a cultured fish subject to low-temperature treatment.
鱼类的表型性别通常具有可塑性。低温处理会诱导其雄性化，产生具有雄性生理性别和雌性遗传性别的伪雄鱼（PM）。为了比较性腺转录组，我们从三组鱼（F、M和PM）中收集性腺进行高通量转录组测序。结果共获得467,640,218条原始 reads（70.15 Gb），共436,151,088条clean reads（65.43 Gb），平均长度为150 bp。F和PM之间仅鉴定出79个差异表达基因（DEG），而F和M之间以及PM和M之间分别鉴定出12,041个和11,528个DEG。根据DEG的功能注释，筛选出13个与性腺发育相关的DEG（、、、、、、、、、、、、和），它们可能参与了伪雄鱼的形成。对这些DEG进行定量PCR验证了RNA测序的可靠性。我们的结果为该鱼类的基因组序列资源做出了重要贡献，并深入了解了低温处理养殖鱼类雄性化的分子机制。
