RESUMO
Accumulation of carotenoid pigments in the shoot apex of etiolated pea (Pisum sativum cv. Alaska) seedlings is completely prevented by ethylene. Under certain conditions carotenoid synthesis is normally controlled by endogenously produced ethylene. The gas completely inhibits carotenoid synthesis induced either by continuous white light or brief illumination with red light, but only partially inhibits light-induced chlorophyll formation. Far red illumination followed by red illumination reverses the action of red light on carotenoid synthesis. Red light-induced carotenogenesis is partly or wholly caused by phytochrome-mediated inhibition of ethylene biosynthesis.
