Complete mitochondrial genome of the Indian peafowl (Pavo cristatus), with phylogenetic analysis in phasianidae

Pavo cristatus, known as the Indian peafowl, is endemic to India and Sri Lanka and has been domesticated for its ornamental and food value. However, its phylogenetic status is still debated. Here, to clarify the phylogenetic status of P. cristatus within Phasianidae, we analyzed its mitochondrial genome (mtDNA). The complete mitochondrial DNA (mtDNA) genome was determined using 34 pairs of primers. Our data show that the mtDNA genome of P. cristatus is 16,686 bp in length. Molecular phylogenetic analyses of P. cristatus was performed along with 22 complete mtDNA genomes belonging to other species in Phasianidae using Bayesian and maximum likelihood methods, where Aythya americana and Anas platyrhynchos were used as outgroups. Our results show that P. critatus has its closest genetic affinity with Pavo muticus and belongs to clade that contains Gallus, Bambusicola and Francolinus.
