Clathrus ruber of the mature fruit bodies have been identified as carotenes, predominantly lycopene and "beta"-carotene—the same compounds responsible for the red and orange colors of tomatoes and carrots, respectively. Lycopene is also the main pigment in the closely related fungus "Clathrus archeri", while "beta"-carotene is the predominant pigment in the Phallaceae species "Mutinus caninus", "M. ravenelii", and "M. elegans". Clathrus ruber Clathrus ruber is a species of fungus in the stinkhorn family, and the type species of the genus "Clathrus". It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies
Labrador Retriever coat colour genetics the colour of the dark pigment, eumelanin, and is referred to as the B (brown) locus. The variation displayed by this locus is observed in many mammals, reflecting a so-called 'dilution', a lightening, of black eumelanin to a brown colour. Initial genetic research excluded a role for the melanocortin 1 receptor and the "Agouti" locus as being the cause of the black dilution trait in dogs. Instead, TYRP1 (tyrosine related protein 1) was found to be responsible. This enzyme is localised to melanosomes, the cellular organelles that produce and store pigments, and serves to catalyze oxidation of eumelanin precursors. In
