Fig. 4From: Fruit ripening: dynamics and integrated analysis of carotenoids and anthocyaninsBiosynthesis and regulation of carotenoids. The red oval indicates the carotenoid biosynthetic pathway in the chromoplasts. The yellow arrows indicate the regulatory mechanisms initiated by ethylene and light which upregulate carotenoid biosynthesis. However, the ABA signaling mediated by PYL 9 inhibits lycopene accumulationBack to article page
