| Outline of Final Research Achievements |
The aims of this study were to determine the involvement of plasma membrane heterogeneity in plant cold acclimation. Specifically, responses of plasma membrane microdomains to cold acclimation were investigated. We found that 1) proteomes and lipidomes of the plasma membrane microdomain from various plant species show considerably dynamic responses to cold acclimation but the responses in some parts were related to differences in the extent of cold acclimation capability of the species used, 2) dynamin-like protein 1E, a cold-responsible microdomain protein, was contributed to the increase in freezing tolerance probably via plasma membrane rearrangement through endocytosis process, and 3) a cold-responsible GPI-anchored protein, beta-1,3-glucanase like protein, was also a component associated with cold acclimation probably in controlling the callose deposition and the intercellular transport system through plasmodesmata.
