The characteristic of corvus pectoralis's complete mitochondrial genome and phylogeny analysis.


ABSTRACT: The Collared Crow (Corvus pectoralis), in the order Passeriformes, it widely distributed in large areas encompassing China and northern Vietnam. It is a vulnerable bird that is of international concern. In this study, we first sequenced and described the complete mitochondrial genome and phylogeny of C. pectoralis. The results showed that the whole genome of C. pectoralis was 16,857 bp long and contains 13 PCGs, 2 ribosomal RNA genes, 23 transfer RNA genes, and 1 loop region. The overall base composition of the mitochondrial DNA was 31.13% for A, 29.52% for C, 24.46% for T, and 14.89% for G, with a GC content of 44.41%. The phylogenetic tree showed that C. pectoralis was clustered with C. brachyrhynchos and then together with other two crows in family Passeriformes. This information will be useful in the current understanding of the phylogeny and evolution of Passeriformes.
