  • After pathogen recognition, a multitude of plant resistance-associated reactions are initiated, such as ion fluxes across plant membranes, the generation of reactive oxygen species (ROS), phosphorylation of specific proteins, activation of cell wall strengthening enzymes, transcriptional activation of several defense related genes, induction of phytoalexins, localized cell death at infection sites (HR response), and induction of systemic acquired resistance in distal plant organs

  • Stressing plants to induce their natural defences could lead to a new range of functional foods enriched with a plant's natural defensive compounds, phytoalexins.


  • "Phytoalexin-enriched foods would be defined as foods with health-promoting activities based on phytoalexins and would be a subclass of functional foods,"

  • "We propose a new area within functional food research called phytoalexin-enriched foods that utilize induced plant compounds or phytoalexins created either pre - or post-harvest that have been traditionally viewed only as plant defensive compounds, but have beneficial health effects," wrote lead author Stephen Boue.
