ATPase 8/6 gene based genetic diversity assessment of snakehead murrel, Channa striata (Perciformes, Channidae)

ATPase 8/6 gene based genetic diversity assessment of snakehead murrel, Channa striata... The mitochondrial DNA (mtDNA) ATPase 8/6 gene has been used in phylogenetic as well as in phylogeographic studies along with other mtDNA markers. In this study, ATPase gene sequences were used to assess the genetic structuring and phylogeographic patterns in Channa striata. Out of 884 nucleotide positions generated in ATPase 8/6 genes, 76 were polymorphic. The study suggested 23 unique haplotypes from 67 individuals of nine populations collected from different riverine systems of India. The ATPase 8/6 sequence revealed highest haplotype as well as nucleotide diversities in Imphal River population and lowest diversities in Tapti River population. The pattern of genetic diversity and haplotype network indicated distinct mitochondrial lineages for Chaliyar population, whereas mismatch distribution strongly suggested a population expansion in mid pleistocene epoch (0.4 Mya) with distinct genetic structuring in C. striata. The baseline information on genetic variation and the population sub-structuring would facilitate conservation and management of this important snakehead murrel. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The mitochondrial DNA (mtDNA) ATPase 8/6 gene has been used in phylogenetic as well as in phylogeographic studies along with other mtDNA markers. In this study, ATPase gene sequences were used to assess the genetic structuring and phylogeographic patterns in Channa striata. Out of 884 nucleotide positions generated in ATPase 8/6 genes, 76 were polymorphic. The study suggested 23 unique haplotypes from 67 individuals of nine populations collected from different riverine systems of India. The ATPase 8/6 sequence revealed highest haplotype as well as nucleotide diversities in Imphal River population and lowest diversities in Tapti River population. The pattern of genetic diversity and haplotype network indicated distinct mitochondrial lineages for Chaliyar population, whereas mismatch distribution strongly suggested a population expansion in mid pleistocene epoch (0.4 Mya) with distinct genetic structuring in C. striata. The baseline information on genetic variation and the population sub-structuring would facilitate conservation and management of this important snakehead murrel.
