The Chromosome-Level Genome of Triplophysa dalaica (Cypriniformes: Cobitidae) Provides Insights into Its Survival in Extremely Alkaline Environment.

ABSTRACT: Lake Dali Nur, located in Inner Mongolia, North China, is alkaline, with Triplophysa dalaica one of the three fish species that not only survive, but thrive, in the lake. To investigate the presence of molecular mutations potentially responsible for this adaptation, the whole-genome sequence of the species was sequenced. A total of 126.5 and 106 Gb data, covering nearly 200× of the estimated genome, were generated using long-read sequencing and Hi-C technology, respectively. De novo assembly generated a genome totalled 607.91 Mb, with a contig N50 of 9.27 Mb. Nearly all whole-genome sequences were anchored and oriented onto 25 chromosomes, with telomeres for most chromosomes also being recovered. Repeats comprised approximately 35.01% of the whole genome. A total of 23,925 protein-coding g
