Abstract

1. The relationship of polymorphisms in the Melanocortin 1 Receptor (MC1R) and Agouti Signalling Protein (ASIP) genes with plumage colour in Japanese quail was investigated by cloning and sequencing the entire coding regions from black, white and maroon Japanese quail embryos at 12 d of incubation. 2. Three SNPs were identified in the MC1R coding region by multiple alignment of sequences from individuals with different plumage colours. A missense C/T mutation located at 169 bp within the Open Reading Frame caused a Ile57Val mutation in the amino acid sequence, and had a significant relationship with the black colour. 3. The expression of MC1R was higher in black plumage quails than that in maroon plumage quails, whereas the expression of ASIP was higher in maroon plumage quails than that in black plumage quails. 4. It is concluded that the black plumage colour in Japanese quails may be caused by either increased production of MC1R or decreased production of ASIP.
