Abstract:
:Land plants directly contact soil through their roots. An enormous diversity of microbes dwelling in root-associated zones, including endosphere (inside root), rhizoplane (root surface) and rhizosphere (soil surrounding the root surface), play essential roles in ecosystem functioning and plant health. Rice is a staple food that feeds over 50% of the global population. Its root is a unique niche, which is often characterized by an oxic region (e.g. the rhizosphere) surrounded by anoxic bulk soil. This oxic-anoxic interface has been recognized as a pronounced hotspot that supports dynamic biogeochemical cycles mediated by various functional microbial groups. Considering the significance of rice production upon global food security and the methane budget, novel insights into how the overall microbial community (i.e. the microbiome) of the rice root system influences ecosystem functioning is the key to improving crop health and sustainable productivity of paddy ecosystems, and alleviating methane emissions. This mini-review summarizes the current understanding of microbial diversity of rice root-associated compartments to some extent, especially the rhizosphere, and makes a comparison of rhizosphere microbial community structures between rice and other crops/plants. Moreover, this paper describes the interactions between root-related microbiomes and rice plants, and further discusses the key factors shaping the rice root-related microbiomes.
