| Outline of Final Research Achievements |
This study aimed to investigate the subcellular localization of the plant's cold sensor protein, phototropin, and identify the organelle involved in the low-temperature sensing within the cell. Mutant forms of phototropin were generated with specific subcellular localizations (plasma membrane, cytosol, and chloroplasts), and plant cells expressing these mutant variants were analyzed to determine if they were capable of sensing low temperatures. The findings demonstrated that plant cells sense low temperatures through phototropin localized on the plasma membrane.
