Characterization of the complete mitochondrial genome of the Grey-backed Shrike, Lanius tephronotus (Aves: Passeriformes): The first representative of the family Laniidae with a novel CAA stop codon at the end of cox2 gene

Abstract

The complete Grey-backed Shrike mitochondrial genome has been sequenced to be 16,820 bp in length, consisting of 37 encode genes: 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. In addition, a single control region was also observed. Compared with other reported Passeriformes mtgenome sequences, three bases CAA were detected at the end of Lanius tephronotus cox2 gene with the downstream adjacent base T. The first base of CAA probably occurred C to U transcript editing event resulting in a normal stop codon UAA.
