Chromosome-Level Genome Assembly of the Butter Clam Saxidomus purpuratus.

ABSTRACT: Herein, we provide the first whole-genome sequence of the purple butter clam (Saxidomus purpuratus), an economically important bivalve shellfish. Specifically, we sequenced and de novo assembled the genome of Sa. purpuratus based on PromethION long reads and Hi-C data. The 978-Mb genome of Sa. purpuratus comprises 19 chromosomes with 36,591 predicted protein-coding genes. The N50 length of Sa. purpuratus genome is 52 Mb, showing the highest continuous assembly among bivalve genomes. The Benchmarking by Universal Single-Copy Orthologs assessment indicated that 95.07% of complete metazoan universal single-copy orthologs (n = 954) were present in the assembly. Approximately 51% of Sa. purpuratus genome comprises repetitive sequences. Based on the high-quality Sa. purpuratus genome, we resolve
