Chemical communication in plant-microbe beneficial interactions: a toolbox for precise management of beneficial microbes.

ABSTRACT

Harnessing the power of beneficial microbes in the rhizosphere to improve crop performance is a key goal of sustainable agriculture. However, the precise management of rhizosphere microbes for crop growth and health remains challenging because we lack a comprehensive understanding of the plant-rhizomicrobiome relationship. In this review, we discuss the latest research progress on root colonisation by representative beneficial microbes (e.g. Bacillus spp. and Pseudomonas spp.). We also highlight the bidirectional chemical communication between microbes and plant roots for precise functional control of beneficial microbes in the rhizosphere, as well as advances in understanding how beneficial microbes overcome the immune system of plants. Finally, we propose future research objectives that will help us better understand the complex network of plant-microbe interactions.
