The complete mitochondrial genome sequence and gene organization of Lepidotrigla Kanagashira (Scorpaeniformes, Triglidae) with phylogenetic consideration

Abstract

The complete mitochondrial genome DNA sequence of Lepidotrigla kanagashira was 16,504 bp in length. It consists of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and one control region. Among 22 tRNA genes, 8 tRNAs were encoded on the L-strand. The overall base composition of the genome is 26.65% for A, 25.42% for T, 30.89% for C and17.04% for G. The phylogenetic tree suggested that L. kanagashira was genetically closest to L. microptera and Chelidonichthys kumu among 13 related species. This study could provide some valuable information for further studies on L. kanagashira.
