Whole mitochondrial genome sequencing- a novel approach for studying Phylogenomics for Anas platyrynchos

Abstract The evolution of duck and its distribution across the globe has been an interesting aspect. Domestication of duck and its evolution was also important to analyze if domesticated duck has migrated to other region of the globe or separate domestication process has occurred in particular region of the world. Mitochondrial genes as D-loop or cytochrome B had been used for studying evolution or molecular phylogeny. In current study, we aim to study phylogenomics for Anas platyrynchos across the globe. Whole mitochondrial genome sequencing for Bengal duck (indigenous duck from West Bengal, India) was performed on illumina platform and gene sequences were analyzed for all 37 mitochondrial genes. Variabilities were observed at nucleotide sequence, but absent in amino acid sequence and corresponding 3D structure of polypeptides coded by mitochondrial genes. We observed Anas platyrynchos from Eurasia (europe and Asia) were clustered together indicating common origin. Extensive variabilities were observed among the chinese duck population. The duck population from US was outgrouped. These ducks might have migrated from China and later bred with wild ducks to evolve as new breed or strain in US.
