Extensive NOR site polymorphism in geographically isolated populations of Golden mahseer, Tor putitora.

Genome - 1 Sept 2009

Singh Mamta, Kumar Ravindra, Nagpure N S, Kushwaha B, Mani Indra, Lakra W S

Abstract excerpt

Analyses of nucleolar organizer region (NOR) site polymorphism using silver staining were carried out in 72 individuals of 5 geographically isolated populations of Tor putitora from India. All Ag-NORs analyzed were constituted by rDNA that was confirmed by the presence of positive fluorescence in situ hybridization (FISH) signals. Analyses of the extra NORs among the populations confirmed the hypothesis that...
