Molecular characterization and effect of diagenesis and maturation of melanin in the fossil record
… eumelanin (dark brown-black in color) and pheomelanin (orange-red in color). Both eumelanin and pheomelanin are complex highly cross-linked biopolymers, being comparable to biomolecules like chitin that are resistant to microbial degradation and diagenetic alteration thereby affording …

The genetic basis of plumage polymorphism in the black sparrowhawk
… plumage was investigated, and eumelanin and pheomelanin levels were found to be tightly correlated in the breast and back contour feathers of juvenile black sparrowhawks. The amount of both eumelanin and pheomelanin produced was negatively correlated with expression of ASIP, as was expression …

New tools for the discovery of pigment gene function
… and to produce cysteinyldopas, the precursors of pheomelanin synthesis made in melanosomes via cysteine oxidation. Tracing and biochemical analyses show that MFSD12 is necessary for the import of cysteine into melanosomes, and, in non-pigmented cells, lysosomes. Indeed, loss of MFSD12 reduced the …

The genomics behind beauty: disentangling the complex coat color genetic architecture of gir breed
… that control the production of eumelanin and pheomelanin through specific signaling pathways. Within the context of population genomics, parameters such as linkage disequilibrium (LD) and effective population size (Ne) allow the characterization of population genetic structure, whereas …
