| Outline of Final Research Achievements |
By obtaining dense time-series NGS data and diverse environmental context data from crop rotation plots, we finally constructed a novel Post-Koch functional ecosystem model. The model revealed that the ecosystem is highly robust to environmental perturbation and that appropriate fertilizer application is important for maintaining soil ecosystem stability. Several factors such as competition among closely related species, offensiveness against plasmid phage, and strong convergence pressure on the trait template were also revealed to support this robustness. Many other important findings were also obtained, including the relationship between carbon fixation, nitrogen metabolism, and fertilizer application, the differentiation between Generalist and Specialist strategies, and more than 200 novel species genomes.
