Complete mitochondrial genome sequence of Glyptothorax annandalei in the Yarlung Zangbo River, Tibet

Abstract

Glyptothorax annandalei belongs to the family of Sisoridae, Glyptothorax. It is distributed in the Yarlung Zangbo River of southwestern China. In this study, we first published the complete mitochondrial genome sequence of Glyptothorax annandalei, which was 16,541 bp in length. This genome consists of two rRNA genes, 22 tRNA genes, 13 protein-coding genes (PCGs), and a putative control region. The overall base composition was for A(31.25%,) for T(25.67%), for C(27.66%), for G(15.42%). The PCGs start with a traditional ATG except for COX1 start with GTG, respectively, and end with stop codon TAA, TAG, or a single T base. All tRNA have the typical clover-leaf structure. The phylogenetic tree of the whole mitogenome sequence is constructed by maximum likelihood (ML) method and the phylogenetic relationship among the family Sisoridae is further analyzed. We expect to provide the theoretical basis for the further study of the phylogenetic relationship, taxonomic status, conservation and management of genetic resources of Sisoridae catfishes.
