    • Research Topics

    Plant Environmental Microbiology Group engage in two research topics. One team is interested in the interaction between land plants and methylotrophic bacteria. Various microorganisms are playing important roles for plant growth. Methylobacterium species that can utilize methanol emitted from plants are mutualistic symbionts that not only utilize methanol but also produce plant hormones. We are conducting functional analysis on their methylotrophy and plant-growth promoting ability. Especially we focus on their lanthanide-dependent methylotrophy. The other team studies about interaction between aquatic microbes and bloom-forming phytoplankton. Studies to date revealed that some marine bacteria symbiotically interact with bloom-forming alga, and induces its propagation. This kind of interspecies interaction may have great impacts on the algal dynamics in nature, i.e. bloom formation. We isolated several bacterial strains that induces algal propagation under low nutrition condition. We are particularly interested in the characterization of the interaction between bacteria and algae at the molecular level.
