Complete mitochondrial genome of Devario shanensis (Cypriniformes: Danionidae: Danioninae): genome characterization and phylogenetic consideration

In this study, a comprehensive analysis is presented on the complete mitochondrial genome and phylogenetic relationships of Devario shanensis, an endemic species to the Irrawaddy drainage in southwestern China. The complete mitogenome sequence of D. shanensis was sequenced to be 16,860 bp long and encompassed 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a non-coding control region. The overall AT content (61.1%) was much higher than GC content (38.9%). Phylogenetic analyses employing maximum-likelihood and Bayesian inference methods on the complete mitogenomes, including D. shanensis and 13 other species, unveiled a close genomic relationship between D. shanensis and Devario interruptus. This work will contribute to the genetic resource enrichment and phylogenetic researches on genus Devario.
