5.3.99.8 agriculture red peppers accumulate increasing levels of total carotenoids during ripening, whereas non-red peppers accumulate lower levels of total carotenoids of varying composition. The expression levels of the phytoene synthase, phytoene desaturase, and capsanthin-capsorubin synthase genes are high in peppers with high levels of total carotenoid. The gene of capsanthin-capsorubin synthase is present in two Capsicum varieties whose ripe colour is yellow 681138
