The mitochondrial genome of Sinibotia robusta of pearl river (Cypriniformes: Cobitidae)

Abstract

We present the complete mitochondrial genome of Sinibotia robusta in this study. The mitochondrial genome is 16 575 bp in length and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. The nucleotide compositions of the light strand are 31.9% A, 25.7% T, 26.9% C and 15.5% G. Except ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. The genus most related to Botia Gray was Leptobotia Bleeker and Parabotia Sauvage, as revealed by phylogenetic relationships derived using a maximum likelihood tree. This mitogenome will help elucidate the morphological systematic complexity and phylogenetic structure of Cobitidae and related species.
