Carotenoid cleavage oxygenases (CCOs) are a family of dioxygenases, which specifically catalyze the cleavage of conjugated double bonds in carotenoids and apocarotenoids in plants. In this study, genome-wide analysis of CCO genes in pepper plants was performed using bioinformatic methods. At least 11 members of the CCO gene family were identified in the pepper genome. Phylogenetic analysis showed that pepper and tomato CCO genes could be divided into two groups (CCDs and NCEDs).
