Intense stresses caused by high-altitude environments may result in noticeable genetic adaptions in native species. Studies of genetic adaptations to high elevations have been largely limited to terrestrial animals. How fish adapt to high-elevation environments is largely unknown. Triplophysa bleekeri, an endemic fish inhabiting high-altitude regions, is an excellent model to investigate the genetic mechanisms of adaptation to the local environment. Here, we assembled a chromosomal genome sequence of T. bleekeri, with a size of ∼628 Mb (contig and scaffold N50 of 3.1 and 22.9 Mb, respectively). We investigated the origin and environmental adaptation of T. bleekeri based on 21,198 protein-coding genes in the genome.

布莱氏三倍体的染色体基因组为其进化和环境适应提供了见解


高海拔环境造成的强烈压力可能会导致本地物种出现明显的遗传适应。对高海拔遗传适应的研究主要限于陆生动物。鱼类如何适应高海拔环境尚不清楚。 Triplophysa bleekeri是一种生活在高海拔地区的特有鱼类，是研究适应当地环境的遗传机制的绝佳模型。在这里，我们组装了T. bleekeri的染色体基因组序列，大小约为 628 Mb（重叠群和支架 N50 分别为 3.1 和 22.9 Mb）。我们根据基因组中 21,198 个蛋白质编码基因研究了T. bleekeri的起源和环境适应。
