Characterization of the mitochondrial genome of Microphysogobio tungtingensis (Cypriniformes) and its taxonomic status

Abstract

In the present study, the complete mitochondrial genome of Microphysogobio tungtingensis has been amplified with 16 pairs of primers. There are 16 627 base pairs has been identified and deposited in the GenBank with accession numbers MN970213. The arrangement was similar to typical vertebrate mitochondrial, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and a noncoding control region. The overall base composition of M. tungtingensis was G + C: 42.9%, A + T: 57.1%, apparently with a slight AT bias. Phylogenetic analysis showed that M. tungtingensis was close to M. fukiensis .
