Abstract :
It’s a commonly known phenomenon that the physical and biotic factors modulate the metabolic pathways in plants. They result into triggering of defense responses in plants against detrimental factors i.e. physical stresses or pathogens. This phenomenon is collectively called as resistance induction and the agent responsible for this phenomenon is termed as resistance inducer or inducer. Resistance induction varies greatly with reference to types of inducers and their mode of interaction. This is entirely dependent upon the plant inducer combination and other physical factors prevailing in the local environment i.e. radiations temperature etc. Resistance has been induced either by using biotic or abiotic stimuli. Variation of abiotic factors such as temperature, radiations and chemicals may induce a number of defense compounds in plants. Biotic factors namely bacteria, fungi and nematodes have also potential to alter biochemical profile of plants. All these factors directly alter the rate of transcription and translation processes in plant cells. A number of studies have concluded that during stress conditions, transcription of genes coding for defence related enzymes and chemicals have been accelerated significantly.
