Sequencing and analysis of the complete mitochondrial genome of Rufous-tailed Shrike, Lanius isabellinus (Passeriformes, Laniidae).

The complete mitochondrial genome of the Rufous-tailed Shrike (Lanius isabellinus) was 16 819 bp in length. The GenBank accession number is KP995437 and the contents of A, T, C, and G are 31.1% (5234 bp), 25.5% (4293 bp), 28.7% (4826 bp), and 14.7% (2466 bp), respectively. Gene organization and length are similar to other species of birds. It comprises 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region. All protein-coding genes use the typical initiation codon ATG, except for COX1 that uses GTG. All the complete stop codons were co-incident with the Black-headed Gull (Chroicocephalus ridibundus) and the Grey-backed Shrike (Lanius tephronotus), except for ND2 that was terminated with TAG. In addition, the phylogenetic relationships of Passeriformes based on complete mitochondrial genome showed that genetic distance of Laniidae and Corvidae was closer than other species.
