The complete mitochondrial genome of Pseudogyrinocheilus prochilus (Cypriniformes: Cyprinidae)

Abstract

The complete mitochondrial sequence of Pseudogyrinocheilus prochilus, an endemic species to China and mainly distributed in upper Yangtze River and its tributaries, was obtained by PCR. It was 16,595 bp in length and comprised 37 mitochondrial genes (22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes) and 2 non-coding regions. The overall base composition of H-strand was 31.40% A, 26.78% C, 16.18% G, and 25.64% T. Most of the genes are encoded on heavy strand, except for eight tRNA and ND6 genes. The composition and order of mitochondrial gene have no unique characteristics compared to most of other fishes.

The complete mitochondrial genome of Homatula pycnolepis (Teleostei, Cypriniformes) in Lantsang River and its phylogenetic analysis

“…ATP8 and ND5 of H. pycnolepis were 3 bp or15 bp longer than that of cyprinid fishes. The majority of protein coding genes (PCGs) initiated with ATG codon whereas COI gene initiated with GTG codon, which was similar to other fishes of Cobitidea and Cyprinidae (Li et al 2013;Que et al 2016;Yue et al 2016). The termination codons of PCGs were TAA (ND1, COI, ATP8, ATP6, ND4L, ND5), TAG (ND2, ND3, ND6) or an incomplete single T residue (COII, COIII, ND4, cyt b), which was similar to most fishes too.…”
