title: Complete mitochondrial genome of the Pseudogastromyzon jiulongjiangensis Chen (Cypriniformes, Homalopteridae) and phylogenetic analysis of the Cyprinoidei.
abstract: The Pseudogastromyzon jiulongjiangensis Chen (Cypriniformes, Homalopteridae) is a promising ornamental and commercial candidate in China. In this study, the complete mitochondrial genome of P. jiulongjiangensis was first determined. It is 16,571 bp length and consists of 22 tRNA genes, 13 protein-coding genes, two rRNA genes, and a control region. Except for eight tRNA and ND6 genes, all other mitochondrial genes are encoded on the heavy strand. Phylogenetic analysis revealed that P. jiulongjiangensis, Formosania lacustris, and other seven fish first clustered into the Homalopteridae clade. Then, the Homalopteridae and Cobitidae formed the sister group. The Catostomoidae and Cyprinidae constituted the sister branch, which is inconsistent with the previous phenotypic report. It is suggested that the taxonomic research might lose some significant evolutionary characters. This study will contribute to phylogenetic analysis of the Homalopteridae and the natural resources conservation of P. jiulongjiangensis.
