The role of rhizodeposits in shaping rhizomicrobiome

Tao Tian et al. Environ Microbiol Rep. 2020 Apr.

Abstract

Rhizomicrobiome, the communities of microorganisms surrounding the root of the plant, plays a vital role in promoting plant growth and health. The composition of rhizomicrobiome is dynamic both temporally and spatially, and is influenced greatly by the plant host and environmental factors. One of the key influencing factors is rhizodeposits, composed of root-released tissue cells, exudates, lysates, volatile compounds, etc. Rhizodeposits are rich in carbon and nitrogen elements, and able to select and fuel the growth of rhizomicrobiome. In this minireview, we overview the generation, composition and dynamics of rhizodeposits, and discuss recent work describing the general and specific impacts of rhizodeposits on rhizomicrobiome. We focus further on root exudates, the most dynamic component of rhizodeposits, and review recent progresses about the influence of specific root exudates in promoting bacterial root colonization, inducing biofilm development, acting as plant defence and shaping the rhizomicrobiome.
