The diversity of indole concerning its production and functional role has been increased in both prokaryotic to eukaryotic systems. The bacterial species produce indole and use as a signaling molecule at interspecies, intraspecies, and even at an interkingdom level for controlling the capability of drug resistance, level of virulence, and biofilm formation. Numerous of indole derivative has been also found to play an important role in the different systems and reported to occurred widespread from bacteria, plants, human and plant pathogens. Indole and its derivatives have been recognized for a defensive role against pests and insects in the plant kingdom. These indole derivatives are produced as a result of breakdown products of glucosinolate at the time of insect attack or physical damages. Apart from the defensive role by these products, in plants, they also exhibit several other secondary responses that may contribute directly or indirectly to the growth and development of plants. The present review summarized recent signs of progress on the functional properties of indole and its derivatives in different plant systems. The molecular mechanism involved in the defensive role played by indole as well as derivative in the plant has also been explained. Furthermore, the perspectives of indole and its derivatives (natural or synthetic) in understanding the involvement of these compounds in diverse plants have also been discussed
