Proposed “Three Faucets and Cisterns Model” as a carotenoid accumulation mechanism for the rice seed system. The rate-limiting key enzymes are displayed as “Faucets,” and the biosynthetic and accumulation machinery are shown as squares representing the “Cisterns.” The metabolite pools of G3P/pyruvate, IPP/DMAPP, carotenes, and xanthophylls are presented as four colors of gray, sky-blue, yellow, and green, respectively. OsDXS2 or stPAC transgenes are signified as blue or red, respectively. Carotene components are composed of lycopene, α-carotenes, and β-carotenes, and xanthophyll components contain lutein, β-cryptoxanthin, zeaxanthin, and violaxanthin
