Skin transcriptome of duck

Transcriptome profiles of skin and feather follicle from two body parts at three physiological stages were constructed to understand the molecular network and excavate the candidate genes associated with the plumulaceous and flight feathers structure. The key series-clusters, many candidate biological processes and genes were identified for the morphogenesis, growth and development of two feather types. Through comparing the results of developmental transcritpomes from plumulaceous and flight feather, we found that DEGs belonging to the family of WNT, FGF and BMP have certain differences; even the consistent DEGs of skin and feather follicle transcriptomes from abdomen and wing have the different expression patterns. Overall design: A total of twelve libraries were sequenced from skin and feather follicle tissues of six groups (n=2 for each; control samples), including the early growth plumulaceous feathers (EP), middle growth plumulaceous feathers (MP), late growth plumulaceous feathers (LP), early growth flight feathers (EF), middle growth flight feathers (MF) and late growth flight feathers (LF).
