The complete mitochondrial genome of Gobiobotia filifer (Teleostei, Cypriniformes: Cyprinidae)

Abstract

The Gobiobotia filifer is a small economic fish which distributes in the upstream of Yangtze River and its distributaries. For the environmental pollution and overfishing, its population declined drastically in recent decades, so it is essential to protect its resource. In this study, the complete mitochondrial genome sequence of G. filifer was determined with PCR technology, which contains 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a non-coding control region with the total length of 16,613 bp. The order and composition of genes were similar to most of the other teleost fish. Most of the genes were encoded on heavy strand, except for ND6 genes and eight tRNAs. Just like most other vertebrates, the bias of G and C has been found in different genes/regions. The complete mitochondrial genome sequence of G. filifer would contribute to better understand evolution of this lineage, population genetics, and will help administrative department to make rules and laws to protect this lineage.
