Following are the list of some of the molecular “danger signals” (column I) and its characteristics (column II)                                                                                         

 Column I                                                                                   Column II

 a) MAMPs                               i) produce from the pathogen molecules support their ability to successfully colonize their host and gain nutritional benefits

b) DAMPs                               ii) A plant response to insect herbivores involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant

c) Effectors                             iii) are conserved among a specific class of microorganisms such as chitin for fungi, flagella for bacteria

d) Elicitor                                iv) molecules secrete from the damaging plant by herbivory such as Prosystemin
