Chromosome-Level Genome Assembly of Protosalanx chinensis and Response to Air Exposure Stress.

is a suitable particular species for genetic studies on nearly scaleless skin, transparency and high sensitivity to hypoxia stress. Here, we generated a high-quality chromosome-level de novo assembly of . The final de novo assembly yielded 379.47 Mb with 28 pseudo-chromosomes and a scaffold N50 length of 14.52 Mb. In total, 21,074 protein-coding genes were predicted. , and had formed a clade, which diverged about 115.5 million years ago. In the air exposure stress experiment, we found that some genes play an essential role during hypoxia, such as , , , and in the circadian rhythm pathway. These genomic data offer a crucial foundation for ecology and adaptation studies, as well as a deeper understanding of the response to air exposure stress.
