Outline Activities
Some plant species develop freezing tolerance when exposed to low, non-freezing temperatures. If freezing tolerance could be provided to cold-sensitive plants, the contribution to stable production of crops would be significant. In our laboratory, we found that hardened cells of Chlorella vulgaris C-27 survive slow freezing to -196°C. We are investigating the mechanism of the development of freezing tolerance of Chlorella. Furthermore, based on the research of Chlorella, enhancement of freezing tolerance of higher plants is also carried out.
