ABSTRACT

Abstract Nowadays, agricultural practices require more original products that could enhance sustainable development with profitable production. Research has therefore been studied over the last decade and an ecofriendly alternative has been developed for conventional agriculture, which allows microorganisms to be used in agriculture. Studies based on microorganisms recommend increasing the use of compounds secreted by microorganisms through metabolic interactions with the host plant. Many studies have shown that there is a wide range of microorganisms, such as bacteria, fungi, rhizobium, mycorrhiza, Trichoderma, and their species release certain types of volatile organic compounds (VOCs) such as acetoin, dimethyl hexadecyl mine, etc. This volatile product excreted by microorganisms can be used as an efficient, effective, and cheaper way to meet plant nutritional requirements. In long-term use it also improves soil fertility and can mitigate heavy metal stress in plants and soils. Long-term use of microorganisms improves soil physical, biological, and chemical activity. These VOCs easily bind to fats and lipids due to their lower molecular weight 250–300 g/mol and lower boiling point. These organic compounds act as signal molecules in the plant cell during stress. Few key characteristics of these volatile compounds in the regulation of plant phytohormone levels and the biological pathway taken by these compounds to mitigate stress within the plant cell have not yet been fully studied. The mechanisms of these volatile compounds associated with growth regulation and their proteomic behavior need to be further explored. This chapter summarizes the profound knowledge of the role of microbial VOCs in innovating microbial technology in future agricultural studies.
