The mitochondrial genome of the yellow-vented flowerpecker, Dicaeum chrysorrheum (Dicaeidae) from southwestern China

Abstract

The yellow-vented flowerpecker (Dicaeum chrysorrheum Temminck & Laugier) is a small bird in the Dicaeidae family. To explore the phylogenetic relationships within the genus Dicaeum, we sequenced the complete mitochondrial genome of D. chrysorrheum using a next generation sequencing platform. The mitogenome of D. chrysorrheum (GenBank accession number, MW629121) has a length of 16,818 bp, with a nucleotide composition of 30.62% A, 23.45% T, 31.34% C, and 14.59% G. The genome is comprised of 13 protein-coding genes, 22 transfer RNA genes, and two ribosomal RNA genes. The total length of the protein-coding genes is 11,402 bp, accounting for 67.8% of the total length of the mitochondrial genome. Of the 13 protein-coding genes, 10 have ATG start codons and three genes terminate with incomplete stop codons. A maximum-likelihood phylogenetic tree of 16 bird species placed D. chrysorrheum and D. agile as sister to the other three Dicaeum species (D. concolor, D. eximium and D. cruentatum). This new mitogenome will be useful for further phylogenetic studies of the genus Dicaeum.
