Phenylpropanoids, Phenylalanine Ammonia Lyase and Peroxidases in Elicitor‐challenged Cassava (Manihot esculenta) Suspension Cells and Leaves

Abstract

Phenolic levels in cells were not enhanced and were, theoretically, too low to be inhibitory. However, in combination and when oxidized they may contribute to defence, because oxidation of esculetin and scopoletin by peroxidase and of esculetin by tyrosinase enhanced their fungitoxicity up to 20-fold.
