Abstract: Rhizosphere are diverse in soil microbial organisms. The mechanisms governing the assembly and function of these microorganisms play key roles in the regulation of physiological processes of their host plants and ecosystem process. Many of these microbial organisms are host-generalists, uniquely present without apparent host specificity. Other microbiota are adapted to specialize with specific host plants. Both generalists and specialists are key players on the fitness of land plants. The dynamic interactions between plant and their microorganisms underlying nature and agriculture systems remain to be elucidated. To study the mechanistic mechanisms involved in whole soil/root microbiomes (generalists and specialists)-their plant hosts interactions in situ, we analyzed belowground samples using metaomics. The questions we asked include: (a) What environmental factors (with emphasis on plant species, spatial and temporal variables, climate gradient, biotic and abiotic strass) are responsible for shaping the composition and function of the soil microbiomes? (b) What strategies of the fungal generalists and specialists used to interact with their plant hosts? (c) How do these dynamic changes in turn affect plant development and ecosystem process? Given the unique ability of rhizosphere microbiomes to provide the majority of plant available nutrients and to use plant and/or soil carbon, our understanding of above questions will advance model development for microbial-plant-soil interactions to maximize those functions in forest and agriculture ecosystem process and sustainability.
