Chromosome-level genome assembly and annotation data for the dung beetle Synapsis davidis

The dataset includes clean sequencing data generated from PacBio HiFi long-read sequencing, Illumina short-read sequencing, Hi-C sequencing, and RNA-seq, as well as the final chromosome-level genome assembly, repeat annotation, gene structural annotation, predicted coding sequences, protein sequences, non-coding RNA annotation, and functional annotation results.

The final assembly spans 1.10 Gb and consists of 10 assembled chromosomes, with a scaffold N50 of 107.51 Mb and a BUSCO completeness of 99.40% based on the endopterygota_odb10 database. A total of 10,955 protein-coding genes were predicted, of which 10,858 genes were functionally annotated in at least one database. These data provide a genomic foundation for studies on dung beetle ecology, evolution, taxonomy, comparative genomics, and the ecological functions of large-bodied dung beetles.
