Data from: Brain size and the expression of pheomelanin-based colour in birds
- 负责人：
- DOI：
- doi:10.5061/dryad.8262
- 摘要：
- Eumelanin and pheomelanin are the most common vertebrate pigments. They generate different colours and are synthesized under different
Data from: Changes in melanocyte RNA and DNA methylation favor pheomelanin synthesis and may avoid systemic oxidative stress after dietary cysteine
- 负责人：
- DOI：
- doi:10.5061/dryad.8j5j72t
- 摘要：
- t the synthesis of the pigment pheomelanin also contributes to cysteine homeostasis in melanocytes, where cysteine can enter the pheomelanogenesis pathway
Data from: Low-quality birds do not display high-quality signals: the cysteine-pheomelanin mechanism of honesty

- 摘要：
- , two elements that switch melanogenesis from eumelanin to pheomelanin. Final bib size is negatively related to pheomelanin levels in the bib feathers. BSO reduced
Data from: Exposure to a competitive social environment activates an epigenetic mechanism that limits pheomelanin synthesis in zebra finches

- 摘要：
- s involved in the synthesis of the pigment pheomelanin in melanocytes seems to help to maintain homeostasis against environmental oxidative stress. Her
Data from: Predation risk determines pigmentation phenotype in nuthatches by melanin-related gene expression effects

- 摘要：
- e of pheomelanin, the sulphurated form of melanin whose synthesis in melanocytes consumes cysteine and consequently reduces the availability of glutathione (GSH)
Data from: MC1R variants affect the expression of melanocortin and melanogenic genes and the association between melanocortin genes and coloration

Data from: Feather melanin and micro-structure variation in dark-eyed junco (Junco hyemalis) across an elevational gradient in the Selkirk Mountains

- DOI：
- doi:10.5061/dryad.ks53j
- 摘要：
- at high elevation had lighter (less melanism) and less brown (less pheomelanin) body contour feathers than at low elevations. High elevation individuals also had lon
Data from: Chronic exposure to low-dose radiation at Chernobyl favours adaptation to oxidative stress in birds

- 摘要：
- rly in GSH levels and DNA damage. 4. We also show that, under equal levels of radiation, the birds that produce larger amounts of the pigment pheomelanin
Data from: A novel locus on chromosome 1 underlies the evolution of a melanic plumage polymorphism in a wild songbird

- 摘要：
- between colour morphs appear to rely upon complex cis-regulatory variation that either prevents the synthesis of pheomelanin in grey feathers
Data from: Melanin-based sexual dichromatism in the Western Palearctic avifauna implies darker males and lighter females

- 摘要：
- of species, meaning that males tend to produce more eumelanin and females tend to synthesize more pheomelanin. This survey has revealed the high prevalence
