The yellow catfish, Pelteobagrus fulvidraco, is a commercially important fish species. It is widely distributed in the fresh water areas of China, including rivers, lakes, and reservoirs. Like many other aquaculture fish species, people have observed significant size dimorphism between male and female yellow catfish and it shows a growth advantage in males.
Here, at the first time, the time-course transcriptome was used to explore the various expression profiles of genes in different gonad developmental stages and genders. A total of 2696 different expression genes (DEGs) were identified from different stages. Based on these DEGs, 13 gonad development related genes were identified which showed time-specific or sex biased expression patterns.
This study will provide the crucial information on the molecular mechanism of gonad development of female and male yellow catfish. Especially, during the different gonad development stages, these 13 gonad development related genes exhibit various expression patterns in female and male individual respectively. These results could inspire and facilitate us to understanding the various roles of these genes play in different gonad development stages and genders.
黄颡鱼（Pelteobagrus fulvidraco）是一种具有商业价值的鱼类，广泛分布于中国的淡水水域，包括河流、湖泊和水库。与许多其他水产养殖鱼类一样，人们观察到黄颡鱼的雌雄个体之间存在显著的大小二型性，雄性个体具有生长优势。
本研究首次利用时间序列转录组技术，探索了不同性别和性腺发育阶段的基因表达谱。从不同阶段共鉴定出 2696 个差异表达基因（DEGs）。基于这些 DEGs，鉴定出 13 个与性腺发育相关的基因，这些基因表现出特定时间或性别偏向的表达模式。
本研究将为黄颡鱼雌性和雄性性腺发育的分子机制提供关键信息。特别是在不同的性腺发育阶段，这 13 个与性腺发育相关的基因在雌性和雄性个体中分别表现出不同的表达模式。这些结果可以启发和促进我们理解这些基因在不同性腺发育阶段和性别的不同作用。
