Outline of Final Research Achievements

β-Citraurin, a C30 apocarotenoid, is a color-imparting pigment responsible for the reddish color of citrus fruits. In the present study, we found that CitCCD4 was involved in the synthesis of β-citraurin, using two citrus varieties of Satsuma mandarin, ‘Yamashitabeni-wase’, which accumulates β-citraurin predominantly, and ‘Miyagawa-wase’, which does not accumulate β-citraurin. The expression of CitCCD4 increased significantly in the flavedo of ‘Yamashitabeni-wase’ during fruit maturation. In addition, function analysis showed that the cleavage of β-cryptoxanthin and zeaxanthin by CitCCD4 enzyme led to the formation of β-citraurin. The results suggested that CitCCD4 was a key gene regulating the biosynthesis of β-citraurin.
