Abstract
Indian magur (Clarias batrachus) is an important freshwater catfish, which is listed as endangered under A3cde+4acde ver. 3.1 categories by the IUCN (2015) due to decreasing population trend. Microsatellites or short sequence repeats (SSRs) tagged to genes have been utilized as gene marker. In the present study, 31,814 SSRs of C. batrachus (magur) were identified using microsatellite identification tool programme from the next generation sequencing data generated on Roche 454 and Ion Torrent platforms. A bioinformatics pipeline, with stringent criteria resulted in selection of 1672 microsatellite loci falling in the genic region. Initially, a total of 30 loci were selected for primer development; and of these 14 were successfully amplified and five were found to be polymorphic in 30 individuals of C. batrachus (magur). The observed as well as expected heterozygosity ranged from 0.038 to 0.526 and 0.434 to 0.784, respectively, and the number of observed alleles ranged from three to five. The study reported the application of next generation sequencing technologies for rapid development of microsatellite loci in Indian catfish species, C. batrachus (magur).Entities:
