Research Interests
Plant Cell Biology Laboratory
 We
have two aims of research. First is to understand
the mechanisms of transport and detoxification of
the pollutants such as heavy metals and herbicides
by plants. The knowledge obtained from this project
can be used for development of plants that can be
useful for phytoremediation or safe crops that do
not absorb pollutants. Second is to understand
how plant cells sense and respond to various internal
and external changes such as light, water stress,
pollutants and herbivores. We identify the components
of the signal transduction pathways that lead to
stomatal movements and plant defense responses,
and investigate how they interact. The knowledge
obtained from this project can be used for development
of plants that are tolerant to drought, pathogen,
and other stresses, or those that can respond rapidly
and efficiently to physiological signals to open
or close stomata, thus optimizing photosynthesis
and water use efficiency.
We
use molecular biological techniques, immunolocalization,
as well as electrophysiological techniques. For
example, patch clamping technique is powerful in
providing information on the activities of individual
ion transporters. We also use expression systems
such as Xenopus oocytes to identify the functionss
of plant transporter genes.
