Novel microsatellite DNA markers for Indian Gharial (Gavialis gangeticus)

Abstract
The present status of existing crocodile species has increased the necessity to develop novel utilities for conservation. We have developed 18 microsatellite loci from the Indian Gharial (Gavialis gangeticus) intended for genomic explanation and applied them to study genetic variation. Polymorphism of each locus was assessed in 32 individuals for G. gangeticus India. The number of alleles per locus varied from 2 to 8 (mean 5.5) for Indian population. Observed and expected heterozygosity ranged from 0.73 to 1.00 and 0.50 to 0.81, respectively and the average polymorphic information content is 0.565. These selected markers are helpful for assessing population structure, intraspecific difference, and conservation and management of G. gangeticus.
