| Outline of Final Research Achievements |
Organisms on the earth detect variation in day-length and anticipate upcoming seasonal changes. The critical day-lengths of photoperiodic responses often show a latitudinal cline due to the local adaptation. In plants, it is well known that the photoperiodic flowering is based on the day-length measurement by the circadian clock. However, the modulation mechanisms of the critical day-length is unclear. Using a short-day duckweed, Lemna aequinoctialis, we found the significant correlation between critical day-lengths and circadian periods. This suggests that the local adaptation of critical day-lengths is likely to involve the modulation of circadian periods.
