Identification and cloning of an NADPH-dependent hydroxycinnamoyl-CoA double bond reductase involved in dihydrochalcone formation in Malus × domestica Borkh.

Proposed biosynthetic pathway leading to p-dihydrocoumaroyl-CoA and dihydrochalcones. The NADPH-dependent reduction of p-coumaroyl-CoA to p-dihydro-coumaroyl-CoA is highlighted.112
