Two new complete mitochondrial genomes (Paradoxornis gularis and Niltava davidi) and their phylogenetic and taxonomic implications

Abstract

All the genes of Paradoxornis gularis and Niltava davidi complete mitochondrial genomes encoded on the H-strand, apart from one PCG (ND6) and eight tRNAs (tRNAGln, tRNAAla, tRNAAsn, tRNACys, tRNATyr, tRNASer(UCN), tRNAPro, and tRNAGlu). Strikingly large tandem repeats were found in the control region (CR) of P. gularis mitogenome. The phylogenetic analysis demonstrated that P. gularis possessed a basal phylogenetic position within the genus Paradoxornis, and N. davidi was more closely related to Cyanoptila cyanomelana than other Muscicapidae species.
