Integrated Analysis of mRNA Expression, CpG Island Methylation, and Polymorphisms in the Gene in Ducks ().

Microphthalmia-associated transcription factor () is a key regulator for the development and function of melanocytes in skin, eye, and plumage pigmentations. Thus, the was selected as a candidate gene associated with plumage coloration in ducks. This study analyzed the mRNA expression, promoter methylation, and polymorphisms in the gene in ducks with different plumage colors (Putian Black, Putian White, Liancheng White, and Longsheng Jade-green).

Isolation of blue-green eggshell pigmentation-related genes from Putian duck through RNA-seq.

Background: The diversity of avian eggshell colour plays important biological roles in ensuring successful reproduction. Eggshell colour is also an important trait in poultry, but the mechanisms underlying it are poorly understood in ducks. This study aimed to provide insights into the mechanism of blue-green eggshell colour generation.
