Abstract

Microbes, insects, and other organisms within the plant environment emit volatiles responsible for various biological and physiological processes that affect the well-being and growth of plants. These volatile organic compounds (VOCs) that are produced by organisms can travel a distance from the locality of emission into the atmosphere, soils, and liquids making them an efficient means of regulating short as well as long-distance interactions between organisms. In this chapter we look into the plethora of VOCs that are emitted in bacteria-bacteria, bacteria-fungi, and bacteria-plant interactions. These VOCs are involved in mutualistic, antagonistic, or symbiotic relationships that regulate cellular, developmental, and biological processes which include growth and plant defenses. Due to the large abundance of microorganisms, the function of these VOCs on other organisms remains poorly understood. Here we have reviewed the role of MVOCs with special emphasis on plant defense and health, alluding to the potential of these compounds to control various processes that result in the plants’ elevated health and defense.
