32 In general, phytohormones are mostly divided into five classes: auxins [indole-3-acetic acid (IAA)], cytokinins (CKs), ethylene, abscisic acid (ABA), and gibberellins (GAs). Apart from phytohormones’ role in plant reactions to changes in environmental conditions, phytohormones are the main factor that regulates the expression of the inherent genetic potential of plants. Several biosynthesis pathways have been recognized and the abundance of phytohormones biosynthesis is extensive among plant-associated pathogenesis strains. 33 Phytohormone biosynthesis by microorganisms plays a critical role in regulating plant development by mediating signaling networks involved in plant responses to a broad range of interactions. Interactions between phytohormones-producing microorganisms and plants cause various results on the plant side, differing from pathogenesis to phytostimulation. For example, there is increasing proof that auxin, is a signaling hormone in microorganisms because auxin influences gene expression in some microorganisms. In this chapter, plant hormone biosynthesis by microorganisms and its role in the association with the plant are discussed.
