Development of microsatellite markers and their utilization in genetic diversity analysis of cultivated and wild populations of the mud carp (Cirrhina molitorella)
چکیده انگلیسی

Microsatellite markers have been increasingly used in genetic studies on fishery species because of their high applicability in selective breeding programs. Here we reported the development of microsatellite markers and their utilization in mud carp (Cirrhina molitorella). An (CA)15 enriched library has been constructed for mud carp, using the magnetic beads enrichment procedure. Sequence analysis of 60 randomly picked positive colonies indicate that 56 (93.3%) of the colonies contain microsatellites. Microsatellite polymorphism was assessed using 10 mud carp individuals, and 12 microsatellite loci turned out to be polymorphic. We utilized these loci to study the genetic diversity of a wild population (WM) and a cultured population (CM) of the mud carp. A total of 109 alleles were detected with an average of 9.08 alleles per locus. The mean value of the observed heterozygosity of WM and CM was 0.6361 and 0.6417, respectively, and significant decrease of genetic diversity in CM was not observed. The genetic distance between the two populations was 0.1546 and the value of GST was 0.0473. This showed that there existed a slight genetic differentiation between WM and CM.
