Abstract:
A comprehensive study of the complex polyphenol biosynthesis in developing leaves of apple (Malus domestica) was performed comprising gene expression, enzyme activities and polyphenol composition. During leaf development, an early increase in gene expression was observed for phenylalanine ammonia lyase (PAL, EC 4.3.1.5), chalcone synthase (CHS, EC 2.3.1.74), flavanone 3--hydroxylase (FHT, EC 1.14.11.9) and dihydroflavonol 4--reductase/flavanone 4--reductase (DFR/FNR, EC 1.1.1.219). Their enzyme...     »
