Abstract
The complete mitochondrial genome sequence of the cockscomb pearl mussel Cristaria plicata, which is an endangered species in South Korea, was sequenced. The circle genome (15,708 bp in size) consists of 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. There were 26 noncoding regions (NCs) found throughout the mitogenome of C. plicata, ranging in size from 2 to 327 bp, and the two largest NC regions, NC286 and NC326, were found between ND5 and tRNAGln (286 bp) and between tRNAGlu and ND2 (326 bp), respectively. The 13 mitochondrial protein-coding genes of a female individual of C. plicata collected from Korea (15,708 bp) were compared to those of the Chinese individual (15,712 bp) published before. The result showed that ND3 is the most conserved with 100% nucleotide similarity, and each of the other protein-coding genes has ca. 99%, respectively. The two largest NCs among 26 NCs have totally 98% nucleotide similarity between Korean and Chinese ones.
