DFR — Capsicum annuum

Summary

CaDFR (T459_23822) on pepper chromosome 9 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 (EC 1.1.1.234, 1.1.1.219). The gene is associated with anthocyanin, flavonoid, phenylpropanoid, carotenoid, and polyamine anabolism, as well as sucrose metabolism, ABA signaling, circadian rhythm, fruit development, sporulation, organogenesis, virus-induced PTGS, stress response, and light response. It is linked to fruit color, anthocyanin and flavonoid content, leaf thickness, pollen fertility, and photosynthetic rate. Studies of related genes in other species connect the family to flower and leaf color, shoot biomass, drought tolerance, chlorophyll and carotenoid content, starch and sugar content, water use efficiency, and quantum yield.
