High-quality chromosome-level genome assembly of the snake Pseudoxenodon stejnegeri (Squamata: Colubridae)

We present a chromosome-level reference genome assembly for P. stejnegeri generated through integrating the PacBio HiFi sequencing, Illumina short-read sequencing and Hi-C scaffolding techniques. The final genome size is 1601.26 Mb, with a scaffold N50 of 203.68 Mb and 97.07% assembled sequences anchored onto 18 pseudo-chromosomes. The BUSCO assessment revealed 97.8% completeness. We predicted 21,678 protein-coding genes, of which 17,531 (80.87%) genes were functionally annotated. Approximately 908.04Mb repeat sequences were detected, representing 56.71% of the assembled sequences
