Complete Mitochondrial Genome and Phylogenetic Analysis of the Blue Whistling Thrush ( Myophonus caeruleus )

The blue whistling thrush ( ) is a bird belonging to the order Passeriformes and family Muscicapidae. 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 We use complete mitochondrial genomes to provide insights into the phylogenetic position of 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 , , , and were clustered into one clade, together with the sister group of .
