Given below are certain statements regarding plant-pathogen interactions: which one of the following is incorrect?

#Section 6: Plant, Animal and Microbial Biotechnology
  1. Plants possess pattern recognition receptors (PRRs) that perceive microbe-associated molecular patterns (MAMPs) present in specific class of microorganisms but are absent in the hosts
  2. The pattern recognition receptors (PRRs) perceive MAMPs or DAMPs by cell surface initiates a localized basal defense response called MAMP-triggered immunity
  3. Effectors bind to their PRRs and R proteins defense responses are induced known as effector-triggered immunity
  4. Systemin is an example of a plant-derived effector molecules found in tomato that is produced in response to wounding associated with herbivore activity
