Molecular phylogeny of Barbin fishes of North-East India based on mitochondrial 16SrRNA gene sequences

The Barbin fishes (Cypriniformes: Barbinae) have achieved great diversity in the world and cosmopolitan in distribution but their phyletic classification is ambiguous. Molecular phylogeny of barbin fishes of North-East India was studied by using mitochondrial 16S rRNA sequences. Partial sequences (540–615 bp) of mit. 16S rRNA genes of four species of barbin fishes-Pethia atra, Puntius chola, P. javanicus, and P. sophore were generated and sequences of 7 species were downloaded from GenBank for present study. The aim of our present study is to resolve the taxonomic relationship and to establish the molecular phylogeny of Barbin fishes of North-East India based on mitochondrial 16S rRNA genes sequences. The Maximum Parsimony Tree shows three clusters with high bootstrap value and present data indicates that allfishesin this group had a common ancestor but now they have separated into distinct evolutionary lineages.
