Sequencing of the complete mitochondrial genome of the common raven Corvus corax (Aves: Corvidae) confirms mitogenome-wide deep lineages and a paraphyletic relationship with the Chihuahuan raven C. cryptoleucus.

摘要: Previous studies based on single mitochondrial markers have shown that the common raven (Corvus corax) consists of two highly diverged lineages are hypothesised to undergone speciation reversal upon secondary contact. Furthermore, ravens paraphyletic with respect Chihuahuan (C. cryptoleucus) DNA (mtDNA). Here we explore causes mtDNA paraphyly by sequencing whole genomes 12 from across Northern Hemisphere, in addition three and one closely related brown-necked ruficollis) using a long-range PCR protocol. Our mitogenomes ranged between 16925-16928 bp length. GC content varied 43.3% 43.8% 13 protein coding genes, rRNAs 22 tRNAs followed standard avian arrangement. The overall divergence clades was 3% (range 0.3-5.8% 16 regions including control region). Phylogenies constructed recovered previously found sister relationship California clade (overall 1.1%), which strengthens hypothesis results distinct Holarctic lineages.
