“…has a promoting effect on maize plant growth under drought stress by inhibiting abscisic acid (ABA) signaling and inducing IAA biosynthesis in a tryptophan-dependent manner [ 106 ]. Except bacteria, studies have showed that some fungi strains with high IAA production can also have a significant promoting effect on the plant growth, diosgenin content, and nutritional value of fenugreek [ 107 , 108 , 109 , 110 , 111 , 112 ].…”

Indole-3-acetic acid (IAA) belongs to the family of auxin indole derivatives. IAA regulates almost all aspects of plant growth and development, and is one of the most important plant hormones. In microorganisms too, IAA plays an important role in growth, development, and even plant interaction. Therefore, mechanism studies on the biosynthesis and functions of IAA in microorganisms can promote the production and utilization of IAA in agriculture. This mini-review mainly summarizes the biosynthesis pathways that have been reported in microorganisms, including the indole-3-acetamide pathway, indole-3-pyruvate pathway, tryptamine pathway, indole-3-acetonitrile pathway, tryptophan side chain oxidase pathway, and non-tryptophan dependent pathway. Some pathways interact with each other through common key genes to constitute a network of IAA biosynthesis. In addition, functional studies of IAA in microorganisms, divided into three categories, have also been summarized: the effects on microorganisms, the virulence on plants, and the beneficial impacts on plants.
