Our understanding of plants is limited, as they exhibit various processes like photosynthesis, metabolic biosynthesis, adaptability, defence mechanism, stress tolerance, reproduction, growth, etc. Despite advancement in plant biology research with existing complete genome sequences available for many crops and plants, plant-plant interaction is still an unresolved mystery. Though researchers have been trying to understand plant communication since the last century, the precise mechanisms have not yet been conclusively deduced. Here, we discuss the need for studies on plant communication, which could serve as a resource for betterment of our understanding of the biological system and also in agricultural disease forecasting. Emerging technologies and minds have to be focused to unravel the mystery of plant communication in order to understand the unknown fact.
