Abstract:

Indole-3-acetic acid (IAA), as a common endogenous auxin, can be synthesized not only by plants, but also by many microorganisms. IAA produced by fungi plays a dual role in fungus-plant interactions, which can promote plant growth and induce plant diseases. Therefore, the research was carried out on the biosynthesis and functional mechanisms of IAA in fungi, which is of great value in promoting the production and utilization of IAA.This article reviewed the main IAA biosynthesis pathways in fungi, the impact of environmental factors on IAA synthesis in fungi, and the role of IAA in the interaction between fungi and plants. It also provided prospects for the relevant research on the cross-border signal transduction mechanism of IAA in fungi.

Key words: indole-3-acetic acid, IAA biosynthesis, interaction between fungi and plants
