The complete mitochondrial genome sequence and phylogenetic position of Gobio coriparoides

Abstract

In this paper, we determined the complete mitochondrial DNA (mtDNA) sequence of Gobio coriparoides and analyzed its phylogenetic position. The complete mitogenome is 16,604 bp in length. It consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region. Among the 37 genes, 28 were encoded on the heavy strand, while 9 were encoded on the light strand. The overall base composition was 28.97% for A, 18.06% for G, 26.54% for T, and 26.43% for C, with a higher A + T content (55.51%). There are some overlaps existing in G. coriparoides mitochondrial genome. The neighbor-joining (NJ) phylogenetic tree based on whole mitogenome sequences supported that G. coriparoides is the closest to G. cynocephalus. This result will provide a basic reference for understanding the genetic structure, molecular evolution, and phylogeny of G. coriparoides and related species.
