Analysis of the complete mitogenome of Oriental turtle dove (Streptopelia orientalis) and implications for species divergence

Publication date: April 2016 Source:Biochemical Systematics and Ecology, Volume 65 Author(s): Zuhao Huang, Feiyun Tu, Robert W. Murphy The Oriental turtle dove, Streptopelia orientalis (Columbiformes: Columbidae) is an extremely widespread species. We investigate and analyze its complete mitochondrial genome. The complete mtDNA genome, a circular DNA molecule of 17,130bp, contains of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a control region. Its base composition is A 29.7%, T 23.9%, G 14.1%, C 32.3%. Similar to other birds and turtles, the Oriental turtle dove has an extra base “C” at position 174 of gene Nd3. The most frequently codon usage is CUA (7.11%), followed by AUC (5.52%), CUC (4.97%) and UUC (4.36%). Genetic distance analyses indicate that the difference between Macropygia phasianella vs Spilopelia senegalensis is lower than that Spilopelia chinensis vs S. orientalis based on both the standard barcoding gene Cox1 and Cytb. Genetic distances coincide with morphological, behavioral and phylogenetic analyses that suggest the assignment of chinensis and senegalensis to the genus Spilopelia, following the latest taxonomic system of the IUCN.
