摘要

White bream Parabramis pekinensis is an omnivorous fish belong to Cyprinidae that is widespread in Asia. In this study, we presented chromosome-level genome assemblies of P. pekinensis by using PacBio HiFi long reads and Hi-C technology. We assembled high-quality genome of 1.03 Gb with scaffold N50 length of 40.04 Mb, and a total of 98.31% of the assembled sequences were anchored to 24 chromosomes. BUSCO analysis revealed that the genome assembly has a high-level completeness of 98.35% gene coverage. A total of 26,542 protein-coding genes were predicted, of which 92.61% were functionally annotated. The phylogenetic analysis indicated that the lineage leading to P. pekinensis was diverged from the lineage to Megalobrama amblycephala approximately 7.6 million years ago. The high-quality genome assembly provide valuable resources for evolutionary study and genetic breeding of genus Parabramis.
