Complete mitochondrial genome of Black Drongo Dicrurus macrocercus (Passeriformes: Dicruridae) and phylogenetic analyses.

The Black Drongo Dicrurus macrocercus is a bird belonging to the group Passeriformes, distributed almost all over the country in China. The conservation status of this species is Least Concern (LC) in IUCN. In this study, the complete mitogenome of D. macrocercus was determined. The mitochondrial DNA is packaged in a compact 17,056 based pair (bp) circular molecule with A + T content of 57.04%. It contains 37 typical mitochondrial genes, including 13 protein-coding genes, 2 rRNAs and 22 tRNAs, and 1 non-coding regions. We reconstructed a phylogenetic tree based on mitogenome sequences of 15 Dicruridae species and one outgroup. In trees, D. macrocercus was clustered as an independent clade with high support value (100). The new mitogenome data would provide useful information for application in conservation genetics and further clarify the phylogenetic evolution of this species.

黑卷尾（Dicrurus macrocercus）是雀形目鸟类，几乎分布于中国全国各地。该物种在世界自然保护联盟（IUCN）中的保护状况为无危（LC）。在本研究中，测定了黑卷尾的完整线粒体基因组。线粒体DNA被包装在一个紧凑的17056碱基对（bp）的环状分子中，A + T含量为57.04%。它包含37个典型的线粒体基因，包括13个蛋白质编码基因、2个rRNA和22个tRNA以及1个非编码区。我们基于15种卷尾科物种和1个外类群的线粒体基因组序列构建了系统发育树。在树中，黑卷尾以高支持值（100）聚为一个独立的分支。新的线粒体基因组数据将为保护遗传学应用提供有用信息，并进一步阐明该物种的系统发育进化。
