| Outline of Annual Research Achievements |
The main part of the project in which we focused on the effects of protists on the root endophytic bacterial communities is completed and the manuscript is submitted to a scientific journal. We showed that microbial predators modulated endophytic communities, which originated in the rhizosphere soil. The modulation of endophytes followed chaotic patterns triggered by changes in the dilution rates of the soil nutrients. Furthermore, the presence of predators enhanced the root colonization of endophytes. Our findings identify a novel key mechanism for the modulation of endophytes and enhance understanding of underground plant-microbe interaction.In addition, our side studies that related to this project produced 4 articles in top journals of soil science.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
We have achieved the majority of our aims in this project so far and majority of the work is done. Everything went smoothly and the article including our major goal is currently submitted to a scientific journal.
|
| Strategy for Future Research Activity |
Although the major part is completed, we still need to make some confirmative experiments. So in the last year of the project we will complete the experiments and finalize the project.
|
| Causes of Carryover |
The planned experiment was delayed due to technical problems. That is why we wanted to spend the money within this fiscal year.
