Sequencing and analysis of the complete mitochondrial genome of Brown Shrike, Lanius cristatus (Passeriformes, Laniidae)

Abstract

The complete mitochondrial genome of the Brown Shrike (Lanius cristatus) was 16 821 bp in length. The accession number was KT004451 and the contents of A, T, C, and G were 31.10%(5237 bp), 25.60%(4309 bp), 28.60%(4814 bp), and 14.60%(2461 bp), respectively. Gene organization and length was similar to other species of birds. It comprises of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region. All protein-coding genes use the typical initiation codon ATG, except for COX1 which was initiated with GTG. All the complete stop codon was coincident with the Black-headed Gull (Chroicocephalus ridibundus) and the Grey-backed Shrike (Lanius tephronotus), except for ND2, which was terminated with TAG. In addition, the phylogenetic relationships of Passeriformes based on complete mitochondrial genomes showed that the genetic distance of Laniidae and Corvidae was closer than others.
