A high-quality chromosome-level genome assembly of the bivalve mollusk Mactra veneriformis.

ABSTRACT: Mactra veneriformis (Bivalvia: Mactridae) is a bivalve mollusk of major economic importance in China. Decreased natural yields of M. veneriformis have led to an urgent need for genomic resources. To address this problem and the currently limited knowledge of molecular evolution in this genus, we here report a high-quality chromosome-level genome assembly of M. veneriformis. Our approach yielded a 939.32 Mb assembled genome with an N50 contig length of 7,977.84 kb. Hi-C scaffolding of the genome resulted in assembly of 19 pseudochromosomes. Repetitive elements made up ∼51.79% of the genome assembly. A total of 29,315 protein-coding genes (PCGs) were predicted in M. veneriformis. Construction of a genome-level phylogenetic tree demonstrated that M. veneriformis and Ruditapes philippinarum di
