Abstract

Abstract:

Since the discovery of indole-3-acetic acid in plants at the end of the 19th century, it has received much attention, indole-3-acetic acid can promote cell growth and differentiation,affect the roots, stems, leaves, and fruits of plants,it has a wide range of applications and has achieved significant research results in various fields such as agriculture and forestry in recent years. This article reviewed the synthesis pathways of indole-3-acetic acid in microorganisms, factors affecting microbial synthesis of indole-3-acetic acid, and the effects of microbial synthesis of indole-3-acetic acid on plants.Considering the current severe environmental pollution situation, the rational use of microbial agents can reduce the pollution of soil, air, and groundwater caused by chemical fertilizers, providing effective methods for sustainable development. The development advantages and potential of microbial synthesis of indole-3-acetic acid in forest applications were summarized and prospected, providing a basis for the improvement of microbial preparations that are widely used, efficient and environmentally friendly microbial preparations with little pollution.

Key words: indole-3-acetic acid, plant-growth-promoting rhizobacteria, growth promotion, application
