RIKEN BioResource Research Center Plant-Microbe Symbiosis Research and Development Team

Team Leader: Yasunori Ichihashi (Ph.D.)

Research Summary

Yasunori  Ichihashi(Ph.D.)

Since most agricultural crops grow in soil, where is one of the richest microbial ecosystems on Earth, plants and microbes are strongly associated with each other. Elucidation of the plant-microbe symbiosis should contribute to building a sustainable solution for world food and environmental problems. Our team plan to construct bioresources and experimental systems of plants and microbes for the symbiosis studies, as well as perform large-scale omics studies on agricultural fields. Through collaborative researches with domestic and international communities, we aim to fully understand regulatory mechanism behind the plant-microbe symbiosis and provide a research platform leading to industrial applications.
