Japanese quail microsatellite loci amplified with chicken-specific primers.

Forty-eight primer pairs for chicken (Gallus gallus) microsatellite loci were tested in polymerase chain reaction (PCR) amplification of Japanese quail (Coturnix japonica) genomic DNA. Amplification products were obtained from 28 primer-pairs (58.3%) after optimizing the PCR conditions. Eleven (22.9%) of these generated specific products and 17 yielded non-specific amplification products. Eight markers (ADL0037, ADL0038, ADL0142, ADL0143, ADL0206, ADL0315, ADL0366, and HUJ0006) were polymorphic and three were monomorphic (ADL0023, ADL0024, and ADL0257) in four Japanese quail populations. Specific amplification products from each of the 11 PCR primers were sequenced. Seven of the eight polymorphic and one of three monomorphic markers contained simple tandem repeats. Six of these microsatellite loci (ADL0037, ADL0315, ADL0142, ADL0143, ADL0366 and ADL0257) may be homologous to the corresponding chicken loci from which the markers were developed.
