The lutein epoxide cycle in higher plants; its relationship to other xanthophyll cycles and possible functions

Garcia-Plazaola, Jose L; Matsubara, Shizue; Osmond, C Barry


Several xanthophyll cycles have been described in photosynthetic organisms. Among them, only two are present in higher plants: the ubiquitous violaxanthin (V) cycle, and the taxonomically restricted lutein epoxide (Lx) cycle, whereas four cycles seem to occur in algae. Although V is synthesised through the β-branch of the carotenoid biosynthetic pathway and Lx is the product of the α-branch; both are co-located in the same sites of the photosynthetic pigment-protein complexes isolated from...[Show more]
