Identification of Polymorphisms in the HERC2-OCA2 Gene Locus and their Association with Feather Color in Quail.
Mutations in the HERC2 and OCA2 genes have the potential to affect pigment deposition and alter feather color in birds. Therefore, in this study, we evaluated HERC2-OCA2 gene locus polymorphisms in Korean and Beijing white quails using RNA-Seq and KASP technology. The expression levels of HERC2 and OCA2 mRNA in skin tissues were analyzed using RT-qPCR. Ten single nucleotide polymorphisms were identified by RNA-Seq, of which three (n.117627564T>A, n.117674275T>G, n.117686226A>C) exhibited significant association with feather color in quail. The expression of OCA2 mRNA was significantly lower in the skin of Beijing white quails than that in the skin of Korean quails. These results suggested that variants in HERC2-OCA2 intergenic region could influence the expression of OCA2, which may underlie diluted feather color in the Beijing white quail.
期刊介绍：
The Journal of Poultry Science will publish original reports and reviews which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: breeding and genetics, nutrition and feeds, physiology, reproduction, immunology, behavior, environmental science, management and housing welfare, processing and products, and health in poultry. Submission of original articles to the Journal is open to all poultry researchers. The review articles are invited papers written by international outstanding researchers. Articles will be published in English, American style.
