Genome skimming yields the complete mitogenome of Chromodoris annae (Mollusca: Chromodorididae)

Abstract

In this study, the complete mitogenome sequence of sea slug, Chromodoris annae (Mollusca: Chromodorididae), has been decoded for the first time by genome skimming method. The overall base composition of C. annae mitogenome is 30.6% for A, 14.5% for C, 17.8% for G, and 37.2% for T, and has GC content of 32.2%. The assembled mitogenome, consisting of 14,260 bp, has unique 13 protein-coding genes (PCGs), 22 transfer RNAs, and two ribosomal RNAs genes. The C. annae has the common mitogenome gene organization and feature of Chromodorididae. The complete mitogenome of C. annae provides essential and important DNA molecular data for further phylogenetic and evolutionary analysis for sea slugs.
