Characterization of the mitochondrial genome of the plain flowerpecker, Dicaeum concolor (Dicaeidae) from Yunnan Province, China

Abstract

The plain flowerpecker, Dicaeum concolor, is a tiny bird classified in the flowerpecker family Dicaeidae, and is an important pollinator and disperser of mistletoes in forests. This species is distributed across South and Southeast Asia. For further phylogeographic studies of D. concolor, the complete mitochondrial genome was sequenced here. The genome (GenBank accession no. MW429430) is 16,796 bp in length and comprises 13 protein-coding genes, 22 transfer RNAs, and two ribosomal RNAs. The GC content of the genome sequence is 45.46%, with an overall base composition of 30.76% A, 30.92% C, 14.53% G, and 23.79% T. A maximum-likelihood analysis placed D. concolor as sister relationship to D. eximium. The mitochondrial genome of the plain flowerpecker will be useful for studies of molecular evolution in flowerpeckers.
