| Outline of Final Research Achievements |
Plasma membrane is the place where plant cells receive signals from the outside and elicit intracellular responses. Various proteins such as receptors and channels are reported to localize on the cell membrane. The sphingolipid- and sterol- enriched functional microdomains, known as lipid raft, is a universal organization principle for cellular membranes in plants. To elucidate the biological function of plant microdomains in environmental stress responses, we analyzed the sphingolipid synthetic pathway of Arabidopsis thaliana, a model plant. Studies on T-DNA insertion mutants for sphingolipid-related genes demonstrated that desaturation of sphingolipids is essential for the cold response of Arabidopsis.
