| Outline of Final Research Achievements |
Ecology, functional features, and network analysis of rhizosphere microorganisms were examined to develop effective plant-symbiotic microbes system by using metagenome analysis. As the result, central microbes in the microbial network, Actinomycetes and arbuscular mycorrhizal fungi widely distributed in the research site located in the Colorado desert, California, USA. As endophytic fungi, Ascomycota was dominant and common there compared to Basidiomycota. Under the drought, root endophytic fungal and bacterial communities differed and the changes in rhizosphere microbial function under the drought were indicated by enzymatic activity and functional gene abundances. For establishment of effective plant-symbiotic microbes system, effective microbes were estimated by adaptability to environments and microbial network analysis, but the actual function should be examined in the future.
