Ten polymorphic microsatellite loci in Tibetan chicken, Gallus gallus domesticus

摘要

Through an improved enrichment protocol, a genomic library for (AC)_(12) repeats was constructed and 34 microsatellite loci were isolated and characterized in an endangered animal, Tibetan chicken, Gallus gallus domesticus. In the 34 loci, ten loci showed a distinct allelic variation ranging from 4 to 14 alleles in 54 individuals tested. Polymorphism information content (PIC) ranged from 0.590 to 0.869 with an average of 0.713. Average observed and expected heterozygosities were 0.7988 (ranged from 0.310 to 1.000) and 0.7495 (ranged from 0.609 to 0.897), respectively. These ten microsatellites loci would be the valuable genetic markers for further investigation of Tibetan chicken.
