Telomere to-telomere gapless genome assembly and annotation of Triplophysa yaopeizhii

The genus Triplophysa is one of the predominant fish groups on the Qinghai-Tibet Plateau (QTP). With the intensification of human impacts, the resources of Triplophysa yaopeizhii, which mainly distributed in the upper reaches of Jinsha River, have gradually decreased. Our study utilized PacBio HiFi, Ultra-long ONT, and Hi-C sequencing to construct the telomere-to-telomere (T2T) gapless genome assembly of Triplophysa yaopeizhii. This is the first T2T genome assembly of the genus Triplophysa. The high-quality genome serves as an essential reference for elucidating the adaptive genetic mechanisms of plateau fish to the unique high-altitude.
