CCR1 — Solanum tuberosum

Summary

StCCR1 (PGSC0003DMG400019825) on potato chromosome 3 encodes a cinnamoyl-CoA reductase (EC 1.2.1.44), an NAD(P)-dependent oxidoreductase with a dehydratase/epimerase domain. The enzyme catalyzes the conversion of 4-coumaroyl-CoA and feruloyl-CoA to their respective aldehydes in the phenylpropanoid pathway. StCCR1 is associated with lignin content and biosynthesis, secondary cell wall morphology, plant height, growth, senescence, and saccharification yield. It has been linked to starch yield and content, shoot fresh weight, chlorophyll and anthocyanin content, drought tolerance, transpiration rate, and salt tolerance. The gene is also associated with wound healing, pigmentation, regulation of anthocyanin anabolism, dedifferentiation, cytokinesis, and hormone and primary metabolism. Related genes in other species link the family to cell wall structure and degradability, and to disease resistance.
