Isolation of tetranucleotide microsatellite loci in the burrowing parrot (Cyanoliseus patagonus)
MetadataShow full item record
We isolated seven novel polymorphic microsatellite DNA loci from the burrowing parrot (Cyanoliseus patagonus) and optimised them for future studies of population differentiation and genetic variation. The loci were screened for polymorphism using 38 samples from wild individuals from three neighbouring colonies in Argentina. The primers amplified ... highly variable loci characterised by 3–10 alleles per locus and their observed and expected heterozygosities ranged from 0.15 to 0.78 and 0.15 to 0.81, respectively. When we analysed 52 samples across Argentina and Chile, we found strong genetic differentiation between the Chilean and the Argentinean subspecies as well as significant differentiation between two geographically separated subspecies within Argentina. Our results indicate the suitability of these microsatellites for investigating further questions regarding the population genetics in this species.
