The complete mitochondrial genome data of Ylistrum balloti (Bernardi 1861) (Bivalvia: Pectinidae) from China

The marine bivalve <i>Ylistrum balloti</i>, 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 <i>Y. balloti</i>. The entire mitogenome of <i>Y. balloti</i> 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 <i>Y. balloti</i> with <i>Y. japonicum</i> and their clustering within the Pectinidae family. This dataset presents the complete mitochondrial genome of <i>Y. balloti</i>, providing insights for studies in evolution, taxonomy, DNA barcoding, and population genetics of <i>Ylistrum</i>.
