Complete mitochondrial genome of the mud loach Misgurnus mizolepis (Cypriniformes Cobitidae) and its phylogenetic position in the Cypriniformes

摘要

The mud loach (Misgurnus mizolepis) is a small benthic species belonging to the family Cobitidae. In this study, I report the first sequencing and assembly of the complete mitochondrial genome of M. mizolepis. The complete mitochondrial genome is 16,647 bp long, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. It has the typical vertebrate mitochondrial gene arrangement. Phylogenetic analysis using mitochondrial genomes of 20 species showed that M. mizolepis is clustered with M. anguillicaudatus and M. bipartitus. This mitochondrial genome provides potentially important resources for studying molecular evolution and biogeography.
