蓝色吹口哨的鹅口疮(Myophonuscaeruleus)是一种属于Passeriformes和Muscicapidae科的鸟类。金雀鱼在中国分布广泛,巴基斯坦,印度,和缅甸,是中国长江南部的常住鸟和长江北部的夏季候鸟。目前,关于M.caeruleus的分类存在一些争议。我们使用完整的线粒体基因组来提供对M.caeruleus的系统发育位置及其在Muscicapidae之间的关系的见解。线粒体基因组(GenBank:MN564936)长16,815bp,包含13个蛋白质编码基因(PCGs),2个rRNA基因,22个tRNA基因,和非编码控制区域(D环)。13个PCG以GTG和ATG开始,以5种终止密码子结束。T的核苷酸组成为23.71%,C为31.45%,A的比例为30.06%,G为14.78%。预测了22个tRNA的二级结构,所有这些都可以形成典型的苜蓿叶结构。有24个不匹配,主要是G-U不匹配。通过系统发育树重建,发现Saxicola,Monticola,Oenanthe,腓尼基鲁聚集在一个分支中,和Myophonus的姐妹组一起.
The blue whistling thrush (Myophonus caeruleus) is a bird belonging to the order Passeriformes and family Muscicapidae. M. caeruleus is widely distributed in China, Pakistan, India, and Myanmar and is a resident bird in the southern part of the Yangtze River in China and summer migratory bird in the northern part of the Yangtze River. At present, there are some controversies about the classification of M. caeruleus. We use complete mitochondrial genomes to provide insights into the phylogenetic position of M. caeruleus and its relationships among Muscicapidae. The mitochondrial genome (GenBank: MN564936) is 16,815 bp long and contains 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and a non-coding control region (D-loop). The thirteen PCGs started with GTG and ATG and ended with five types of stop codons. The nucleotide composition of T was 23.71%, that of C was 31.45%, that of A was 30.06%, and that of G was 14.78%. The secondary structures of 22 tRNAs were predicted, all of which could form typical cloverleaf structures. There were 24 mismatches, mainly G-U mismatches. Through phylogenetic tree reconstruction, it was found that Saxicola, Monticola, Oenanthe, and Phoenicurus were clustered into one clade, together with the sister group of Myophonus.
