Abstract:

To identify factors governing peel-color development in mandarins, we examined carotenoid content and composition and the expression of carotenoid-related genes during four stages of ripening (i.e., green, breaker, yellow, and orange) in two varieties: a'Ora', which has orange fruit, and a'Shani', which has orange-reddish fruit. The two varieties had different carotenoid compositions, and a'Shani' had a significantly higher level of total carotenoid pigments. a'Shani' was rich in the deep orange β-cryptoxanthin and the orange-reddish β-citraurin, whereas a'Ora' was rich in the orange violaxanthin. RNA-Seq analysis revealed significantly greater expression of the carotenoid-biosynthesis genes PSY, βLCY, βCHX, and CCD4b, as well as MEP-pathway genes and several ethylene-biosynthesis and-signaling genes in a'Shani' fruit. In contrast, the expression levels of genes involved in the synthesis of α-branch carotenoids (i.e., Îμ LCY and Îμ CHX) and ZEP, which is involved in the formation of violaxanthin, were significantly higher in the a'Ora' fruit. © 2019 American Chemical Society.
