Chicken feathers constitute a major waste in poultry processing due to their resistance to degradation. Microbial degradation offers a promising solution for enhancing the utilization of feather waste. However, the metabolic mechanisms underlying microbial feather degradation remain poorly unders...

Sexually Dimorphic Sail Feathers in the Mandarin Duck: A Model for Lifelong Developmental Modulation [ChIP-seq]
The aim of the experiment is to identify genes that are contributing too variation in the intensity of reddish/brown colouration seen in feathers from a wild x domestic advanced intercross line of chickens. RNA was isolated from growing feathers with varying levels of reddish/brown colouration (eg. ...
ORGANISM(S): Gallus gallus 
Plumage color plays a prominent role in reproductive isolation and thus understanding the genetic basis of pigmentation patterns can provide critical insight into speciation. Subspecies of the dark-eyed junco (Junco hyemalis) show marked differences in melanic plumage coloration known to have evolve...

Sexually Dimorphic Sail Feathers in the Mandarin Duck: A Model for Lifelong Developmental Modulation [RNA-seq]
Birds and other reptiles possess a diversity of feather and scale-like skin appendages. Feathers are commonly assumed to have originated from ancestral scales in theropod dinosaurs. However, most birds also have scaled feet, indicating birds evolved the capacity to grow both ancestral and derived mo...

Subdivision of ancestral scale genetic program underlies origin of feathers and avian scutate scales
Developmental processes extend beyond embryogenesis to support lifelong tissue adaptations. Avian feather follicles, with their resident stem cells and capacity for cyclic regeneration, provide a dynamic model for postnatal tissue remodeling. Here, we propose the Mandarin duck (Aix galericulata) as ...
