  9. 9. Plants can increase their level of resistance is by intensifying the responsiveness of their immune system upon recognition of selected signals from their environment. This so- called priming of defence can provide a memory of resistance, which is based on a faster and/or stronger defence reaction upon pathogen or pest attack.
  10. 10. Priming can target various layers of induced defence. Priming ranges from early responses controlled by adjustments in hormone-dependent signalling pathways and ROS to long lasting events Pastor, V., Luna, E., Mauch-Mani, B., Ton, J., Flors, V.
