Explanation:
Detailed explanation-1: -Elicitation of phytoalexins Phytoalexins are de novo synthesized antimicrobial compounds by plants, as part of the action to defend against invading pathogens. Phytoalexins provide disease-resistance against pathogens but the mode of action varies depending on the types of host–pathogen interaction.
Detailed explanation-2: -The other main difference between plant and animal immunity is that while animals exposed to infection can adapt and acquire immunity, plants cannot. Instead, their ability to recognise and repel specific attackers is hard-wired into their genes.
