Telomeric DNA length and phylogenetic relationship of Baikal and Siberian planarians (Turbellaria, Tricladida)

Dynamics of the telomeric DNA (tDNA) length and the phylogeny of Baikal and Siberian planarians have been studied based on analysis of 18S rDNA and β-actin gene fragments. It was shown that there is a relationship between tDNA length and planarian size. Giant planarians, with a minor exception, have...

Description
Summary:Dynamics of the telomeric DNA (tDNA) length and the phylogeny of Baikal and Siberian planarians have been studied based on analysis of 18S rDNA and β-actin gene fragments. It was shown that there is a relationship between tDNA length and planarian size. Giant planarians, with a minor exception, have longer tDNA than do smaller planarians. Phylogenetic affinity between species that have stretched tracks of tDNA, large sizes, and similar habitats denotes the possible role of tDNA in the development of the high regenerative capacity of planarians.
