Description Plants are a nearly unlimited source of phytochemicals. The plants produce various secondary metabolites, which are useful in its interaction with the environment, various stress factors and development of resistance against
pathogen attack. A wide array of external stimuli are capable of triggering changes in the plant cell which leads
to a cascade of reactions, ultimately resulting in the formation and accumulation of secondary metabolites which
helps the plant to overcome the stress factors. The biotic and abiotic elicitors can result in an enhancement of the
secondary metabolite production. The stimuli are perceived by receptors, which then result in the activation of
the secondary messengers. These then transmit the signals into the cell through the signal transduction pathways
leading to gene expression and biochemical changes. There is interplay of the signaling molecules also which
regulates the entire pathway. This review is oriented towards the factors, which influence signal transduction
pathway(s) with special reference to polyamines, calcium, jasmonates, salicylates, nitric oxide and ethylene. The
interplay of these components to elicit a defense response is discussed. Molecular aspects of disease resistance and
regulation of plant secondary metabolism has also been presented.
