A research into understanding the molecular mechanisms  that enable plants to adapt to multiple environmental stresses.

The researches currently being done are shown below.

Plant adaptation mechanisms to nutrient stresses

Nutrient availability, in particular the availability of sugar (carbon, C) and nitrogen (N), is important in the regulation of plant metabolism and development. This has become an important issue related to changes in plant photosynthesis, biomass, crop yield, and associated with an increase in atmospheric CO₂ concentration, which is a global environmental problem. We have identified several key components of these nutrient signaling and are developing advanced analysis of plant C/N response.

Flowering regulation by nutrients

Flowering is the important phase transition from vegetative growth to reproductive growth, which is modulated by multiple environmental stimuli. We are investigating the integration mechanism of nutrient signal and flowering regulation.

Crosstalk between nutrient and plant immunity

Plants sense pathogen attack at cell surface by the pathogen receptor proteins and induce cellular defense response (ex. ROS burst, programmed cell death). We are investigating molecular mechanism modulating plant immunity under different nutrient conditions.
