Abstract

The complete mitochondrial (mt) genomes of five subspecies of the Eurasian (Common) magpie Pica pica were determined for the first time. Lengths of the circular genomes comprise 13 protein-coding genes, two rRNA genes (for 12S rRNA and 16S rRNA), 22 tRNA genes, and the non-coding control region (CR). Gene content and lengths of the genomes (16,936–16,945 bp) are similar to typical vertebrate mt genomes. The subspecies studied differs by several single substitutions and indels, especially in the CR. The phylogenetic tree based on complete mt genomes shows a deep divergence of the two groups of subspecies which supports the proposed division into two distinct species: P. pica and P. serica.

首次确定了欧亚喜鹊Pica pica五个亚种的完整线粒体（mt）基因组。环状基因组的长度包括13个蛋白质编码基因、两个rRNA基因（12S rRNA和16S rRNA）、22个tRNA基因和非编码控制区（CR）。基因组的基因内容和长度（16,936–16,945 bp）与典型脊椎动物 mt 基因组相似。研究的亚种因几个单一替换和插入缺失而有所不同，尤其是在 CR 中。基于完整 mt 基因组的系统发育树显示了两组亚种的深刻分歧，这支持了将其分为两个不同物种的提议： P. pica和P. serica 。
