Myxoxanthophyll Myxoxanthophyll Myxoxanthophyll is a carotenoid glycoside pigment present (usually as rhamnosides) in the photosynthetic apparatus of cyanobacteria. It is named after the word ""Myxophyceae"", a former term for cyanobacteria. As a monocyclic xanthophyll, it has a yellowish color. It is required for normal cell wall structure and thylakoid organization in the cyanobacterium "Synechocystis". The pigment is unusual because it is glycosylated on the 2'-OH rather than the 1'-OH position of the molecule. Myxoxanthophyll was first isolated from "Oscillatoria rubenscens" in 1936. The bright red pigment lycopene is the acyclic precursor of all carotenoids in cyanobacteria. In myxoxanthophyll synthesis, lycopene is
Cockatiel colour genetics essentially gone. It is only covered up by more grey pigment. There are a tremendous number of colour varieties (combined mutations), including ADMpied Cinnamon, genuine albino, Opaline Cinnamon, Creamino, White-faced Cinnamon, White-faced Opaline. The genuine albino cockatiel is the exact genetic equivalent of any other albino mutation in other parrot species such as the budgerigar, the celestial a.k.a. Pacific parrotlet, the Indian-ringnecked subspecies of rose-ringed parakeet, the splendid a.k.a. scarlet-chested parrot and the white-eye-ringed lovebird species. Throughout all parrot and parakeet species, the genuine albino mutation is always produced by the visual combination of the genuine blue mutation, otherwise known
