Mode of Communication Between Plants During Environmental Stress

Abstract

Plants are considered to be intelligent enough to communicate with each other. This happens with the help of signals that are emitted by the emitter plant in response to any biotic or abiotic inducer. These signals are perceived by neighboring plant (receiver) and which enables them adapt better to the stress conditions. Plants communicate with the help of biological as well as chemical mediator or sometimes without any mediator. These cross-talks are mainly dedicated to share the information about the invading pathogen, mechanical injuries, and availability of light and nutrient. Generally, emitters are less benefited in all communications still the phenomenon evolves because it benefits the other member of emitter species. Plant communication is beyond the species boundary, both inter and intra species communications occur in nature. A very fine interplay of various gene networks regulates this communication resulting in change of gene expression profiles in both emitter as well as receiver plant. Plant communication might be used in future to protect crops against necrotrophic as well as biotropic pathogens.
