Inducible defense against pests or pathogens, involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant. 

These compounds belong to a broad group of chemicals called elicitors

Necrotrophs are Opportunistic, unspecialised (‘non-obligate’) pathogens and Host cells killed rapidly

Entry unspecialised via wounds or natural openings

Secrete copious cell-wall-degrading (lytic) enzymes and toxins

Appressoria/haustoria not normally produced

Wide host range

Easy to culture axenically

Survive as competitive saprotrophs

Controlled by jasmonate- and ethylene-dependent host-defence pathways
