ABSTRACT
Plants are considered as immobile organisms with poor sensitivity and limited ability to respond. Work on plant neurobiology was accepted only as a pseudoscience for a long time by the scientific community. Communication in plants can be categorized into: within plant, between plants, and communication with beneficial organisms. Airborne signals are diffused to reach neighbouring undamaged plants giving them a chance to strengthen their own defense system. Parasitic plants are important components of both natural and agricultural ecosystems and have considerable influence on structure and dynamics of the communities they inhabit. Plants exhibit different cooperative or antagonistic behaviours according to the degree of relativeness among them. Plants are influenced by abiotic and biotic environmental factors wherein, changes in plant physiology and genome dynamics are exhibited as resistance responses. Studies suggest that root apices along with their primary role in the uptake of nutrients, also support neuronal-like activities based on plant synapses.
