The complete mitochondrial genome of Xenocypris yunnanensis (Nichols, 1925), threatened fishes of the world

Abstract

Xenocypris yunnanensis is an endemic species subsisted in Dianchi Lake in China and has been listed as one of the most dangerous species due to the invasion of alien species. In the present study, we determined the first complete mitochondrial genome of X. Yunnanensis, This genome was 16,630 bp in size and contained 37 genes (13 protein-coding genes, two ribosomal RNA, 22 transfer RNA genes and one control region). The overall base composition of the heavy strand is that the 31.25% for A, the 27.20% for C, the 16.15% for G and the 25.40% for T. In this study, the complete mitochondrial genome sequencing for X. yunnanensis was determined for the first time. The result of phylogenetic analysis indicated is that X. yunnanensis is clustered in genus Xenocypris as expected. Also, The mitochondrial genome sequencing of X. yunnanensis provided important molecular data for conservation genetic studies.
