Complete mitochondrial genome identification of Niwaella nigrolinea (Cypriniformes: Cobitidae).

In this study, the complete mitochondrial genome of Niwaella nigrolinea (Cypriniformes: Cobitidae) from Zhejiang, China, was determined for the first time. We found that the sequenced length of the complete mitochondrial genome of N. nigrolinea was 16,565 bp. The genome contained 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and two non-coding regions, identical to most other vertebrates. Our phylogenetic analysis results confirmed that N. nigrolinea was close to an unclassified Cobitis sp . and the fishes of the genus Cobitis . These data would contribute to the genetic conservation genetics and stock evaluation of N. nigrolinea.
