Abstract
The marine bivalve Ylistrum balloti, an economically important species found in the South China Sea, remains largely unexplored in terms of its genetic background. In this study, we have determined the complete mitochondrial genome of Y. balloti. The entire mitogenome of Y. balloti spans 19484 bp, with a base composition of 21.94% A, 13.12% C, 29% G and 35.94% T. The genome contains 13 protein-coding genes (PCGs), 3 ribosomal RNA (rRNA) genes, 23 transfer RNA (tRNA) genes, and a major non-coding region (MNR). A phylogenetic analysis, based on 12 protein-coding genes (PCGs) from 15 species within related taxa, supported the grouping of Y. balloti with Y. japonicum and their clustering within the Pectinidae family. This dataset presents the complete mitochondrial genome of Y. balloti, providing insights for studies in evolution, taxonomy, DNA barcoding, and population genetics of Ylistrum.
