Metabolites of Chemical Signaling Pathways from Crop–Microbe Interactions

Crop–microbe interactions play an important role in plant growth, development, and health. These interactions are mediated by chemical signals, which are produced and perceived by both the plant and the microbe. Chemical signaling pathways in crop–microbe interactions involve a range of metabolites, including phytohormones, secondary metabolites, and volatile organic compounds (VOCs). These metabolites can impact plant growth, stress response, and defense mechanisms. There is an increasing interest in understanding the chemical signaling pathways involved in crop–microbe interaction and the metabolites that mediate these pathways to develop new strategies for improving crop productivity and sustainability by harnessing the potential of these metabolites. This chapter highlights the importance of different chemical signaling pathways and metabolites involved in crop–microbe interactions for sustainable agriculture and for the development of novel bio-based products for crop protection and increasing yield and also emphasizes the need for research in this emerging field.
