DFR — Cucumis sativus

Summary

CSA_3G098550 (DFR, CsDFR, CCR4) on cucumber chromosome 3 encodes a protein with NAD(P)-binding and epimerase/dehydratase domains that exhibits dihydroflavanol 4-reductase, flavanone 4-reductase, anthocyanidin reductase, cinnamyl-alcohol dehydrogenase, and racemase/epimerase activities, along with NADP binding and general oxidoreductase activity. The gene is associated with anthocyanin and flavonoid biosynthesis, secondary and sucrose metabolism, fruit development, and nuclear localization. It is linked to fruit color, carotenoid content, and photosynthetic rate. Studies of related genes in other species connect the family to flower and petal color, leaf traits, shoot biomass, flavonoid and anthocyanin content, chlorophyll content, photosynthetic parameters, water use efficiency, starch and sugar content, pollen fertility, and drought tolerance.
