The suppression of AtPrx52 affects fibers but not xylem lignification in Arabidopsis by altering the proportion of syringyl units.

Physiologia plantarum - 1 Jul 2015

Fernández-Pérez Francisco, Pomar Federico, Pedreño María A, Novo-Uzal Esther

Abstract excerpt

Lignins result from the oxidative polymerization of three hydroxycinnamyl (p-coumaryl, coniferyl and sinapyl) alcohols in a reaction mediated by peroxidases (EC 1.11.1.7) and laccases (EC 1.10.3.2), yielding H, G and S units, respectively. Although both acidic and basic peroxidases can oxidize p-coumaryl and coniferyl alcohol, only basic peroxidases are able to oxidize sinapyl alcohol. The AtPrx52 from...
