Every organism on earth lives under various kinds of environmental stress.
We investigate the mechanisms of adaptation of plants, mainly microalgae,
to stress, using physiological, biochemical, and molecular biological techniques.
The research covers the microenvironment of functional proteins in the
cells and the phylogeny of microalgae. The following research projects
are being conducted at present.

1) The effects of CO2 concentration on microalgae: The role of pyrenoid, which is a compartment
chloroplast, in photosynthesis and
the regulation of gene expression of carbonic anhydrase are being
investigated. The biotechnology of CO2 fixation in microalgae is also explored.
2) The phylogeny of microalgae on the basis of Rubisco genes (rbcL, rbcS):
Haptophyta, including calcareous
microalgae, is the focus of
this research. Genes responsible for calcification are also being sought.
3) Lipid synthesis in chloroplast and its role in thylakoid membrane: How
the change in lipid composition
affects proteins responsible
for photosynthesis is being studied.
