a) Alkaloids are derived from the tryptophan as constitutively produced defensive secondary metabolites

b) These benzoxazinoids such as DIBOA and its derivative DIMBOA are usually stored in the peroxisome

c) Upon damage, the inactive glycosides are hydrolyzed, generating glucosinolate, which are toxic not only to insect herbivores but also against pathogens

d) DIBOA and DIMBOA perform insecticidal and pesticidal activities

e) It can be inactivated by hydroxylation and N-glycosylation reactions
