Analysis of the mitochondrial DNA variation in pond smelt Hypomesus olidus (Osmeridae)

Analysis of the mitochondrial DNA variation in pond smelt Hypomesus olidus (Osmeridae) Pond smelt Hypomesus olidus (Pallas, 1814), one of the five species of the genus Hypomesus, family Osmeridae, was examined for intraspecific variation of the mitochondrial DNA cytb (1062 bp) and COI (567 bp) genes. Among the ten single substitutions discovered, only one, leading to the substitution of isoleucine by valine, was nonsynonymous, while the remaining substitutions were synonymous. The degree of genetic divergence among pooled nucleotide sequences in H. olidus populations examined constituted 0.4% on average, ranging from 0.2 to 0.6%. These values were not higher than the levels of divergence between the individuals within the populations. Phylogenetic analysis of the populations examined did not reveal their subdivision depending of their geographic location, and pointed to the absence of intraspecific differentiation of the species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Pond smelt Hypomesus olidus (Pallas, 1814), one of the five species of the genus Hypomesus, family Osmeridae, was examined for intraspecific variation of the mitochondrial DNA cytb (1062 bp) and COI (567 bp) genes. Among the ten single substitutions discovered, only one, leading to the substitution of isoleucine by valine, was nonsynonymous, while the remaining substitutions were synonymous. The degree of genetic divergence among pooled nucleotide sequences in H. olidus populations examined constituted 0.4% on average, ranging from 0.2 to 0.6%. These values were not higher than the levels of divergence between the individuals within the populations. Phylogenetic analysis of the populations examined did not reveal their subdivision depending of their geographic location, and pointed to the absence of intraspecific differentiation of the species.
