Microbial Volatile Compounds and Their Role in Growth, Development and Resistance in Plants

Abstract

Microbial Volatile Compounds (MVCs) are low molecular weight and low boiling point, high vapour pressure biochemical compounds, produced by a wide array of microorganisms ranging from bacteria to fungi. MVC are forms an interface for below and above soil interaction between microorganisms and plants. Global agricultural systems are under increasing pressure to deliver sufficient, healthy food for a growing population. MVCs can be of great benefit to plants and their use in agriculture thanks to their ability to inhibit the growth and development of plant pathogens, induce the activation of plant defense, or promote plant growth and development. Owing to their natural origin, MVCs have potential as possible alternatives to synthetic pesticides, fungicides, and bactericides as well as genetic modification. Recent studies have yielded mixed results regarding the application of MVCs. Hence, there is an urgent need to explore MVCs in more detail, including dose standardization, compatibility, method of application, and cost-effectiveness to integrate them into mainstream agriculture.
