==== Phycobilins ====
[[Phycobilin]]s are a third group of pigments found in [[cyanobacteria]], and [[glaucophyte]], [[red algal]], and [[Cryptomonad|cryptophyte]] chloroplasts.<ref name="Kim-2009" /><ref name="Howe-2008">{{cite journal | vauthors=Howe CJ, Barbrook AC, Nisbet RE, Lockhart PJ, Larkum AW | title=The origin of plastids | journal=Philosophical Transactions of the Royal Society of London.
