The complete mitochondrial genome sequences of the two sister species, Scandinavian willow ptarmigan and Icelandic rock ptarmigan , were characterized using next-generation sequencing. The mitogenome for willow ptarmigan was 16,677 bp long, with base composition of 30.3% A, 30.8% C, 13.3% G and 25.6% T, with a GC content of 44.1%, while for rock ptarmigan mitogenome was 16,687 bp long, with base composition of 30.2% A, 30.6% C, 13.4% G and 25.8% T, and a GC content of 44.0%. Like other Galliformes species, the mitogenomes comprised of 13 protein-coding genes, 22 tRNA, 2 rRNA and 2 non-coding regions; and control region (D-loop). All genes except and 8 tRNA were encoded on the + strand. All protein-coding genes started with ATG, except for , where a GTG codon was present in both willow ptarmigan and rock ptarmigan. Phylogenetic analysis of the two novel mitogenomes with other Galliformes species demonstrates close relationship within the Tetraoninae subfamily.
利用下一代测序技术对两个姊妹物种——斯堪的纳维亚柳雷鸟和冰岛岩雷鸟的完整线粒体基因组序列进行了特征分析。柳雷鸟的线粒体基因组长度为16,677 bp，碱基组成为30.3%A、30.8%C、13.3%G和25.6%T，GC含量为44.1%；而岩雷鸟的线粒体基因组长度为16,687 bp，碱基组成为30.2%A、30.6%C、13.4%G和25.8%T，GC含量为44.0%。与其他鸡形目物种一样，线粒体基因组由13个蛋白质编码基因、22个tRNA、2个rRNA和2个非编码区组成；以及控制区（D环）。除 和8个tRNA外，所有基因均在正链上编码。所有蛋白质编码基因均以ATG起始，但 除外，在柳雷鸟和岩雷鸟中该基因均以GTG密码子起始。对这两个新的线粒体基因组与其他鸡形目物种进行的系统发育分析表明，在松鸡亚科内它们关系密切。
