DFR — Solanum tuberosum

Summary

PGSC0003DMG400017842, designated StCCR1 (also known as DFR, CCR1, SNL6, StCCR2, StCCR3, CCR3, CCR2) on potato chromosome 8, encodes a cinnamoyl-CoA reductase with oxidoreductase activity, including dihydroflavanol 4-reductase and flavanone 4-reductase activities, and belongs to the 3Beta_OHSteriod_DH/Estase and NAD(P)-bd_dom_sf families. This gene is associated with anthocyanin, flavonoid, phenylpropanoid, and lignin anabolism, as well as pigmentation, secondary metabolism, starch metabolism, and green leaf volatile biosynthesis. It is associated with defence responses against bacteria and fungi, toxin breakdown, circadian rhythm, and histogenesis. The encoded protein localises to the cytoplasm. Associations with flower and leaf colour, anthocyanin content, and starch content have been noted. Studies of related genes in other species link the family to cinnamoyl-CoA reductase (EC 1.2.1.44) and dihydroflavanol 4-reductase (EC 1.1.1.219) activities, and to traits such as fruit diameter, fruit weight, and plant height.
