Root-secreted compounds have impacts on soil nutrient dynamics and plant-microbial interactions in the rhizosphere. In order to understand a microcosmic biosphere "the rhizosphere," we are studying both functions of microbes and plants and their interactions.
1) Study on functions of root-secreted compounds and microorganisms involved in P dynamics in soils (Wasaki, J.)
Rhizosphere, Plant-microbial interaction, Root exudates, Phosphorus
right) Lupine plants which can grow well under low P condition.
left) Cluster root formed by lupin plants to enhance P acquisition.
