Pheomelanin pigment remnants mapped in fossils of an extinct mammal [PDF]
Nature Communications, 2019 AbstractRecent progress has been made in paleontology with respect to resolving pigmentation in fossil material. Morphological identification of fossilized melanosomes has been one approach, while a second methodology using chemical imaging and spectroscopy has also provided critical information particularly concerning eumelanin (black pigment) residue.

Genetic Mapping and Biochemical Basis of Yellow Feather Pigmentation in Budgerigars [PDF]
Cell, 2017 Parrot feathers contain red, orange, and yellow polyene pigments called psittacofulvins. Budgerigars are parrots that have been extensively bred for plumage traits during the last century, but the underlying genes are unknown. Here we use genome-wide association mapping and gene-expression analysis to map the Mendelian blue locus, which abolishes ...

2D excitation-emission fluorescence mapping analysis of plant food pigments
Food Chemistry, 2023 Homogeneous dispersion of plant food pigments is indispensable to study their characteristic fluorescence features for non-destructive rapid monitoring of food systems. However, it is highly challenging to obtain such optical grade homogenized stable dispersion of various plant pigments in aqueous media for tracing their precise fluorescence signatures.
