| Outline of Final Research Achievements |
Flowers of E. grandiflorum and tomato exhibited rapid flower opening/closure immediately after the onset of light /dark period, as well as circadian clock regulated diurnal flower opening and closure. The immediate flower opening after the onset of light period appeared to be regulated mainly by blue light, while the synchronization of circadian clock to the light rhythms appeared to be achieved by either blue or red signals. The experiment using photoreceptor mutants in tomato suggested the involvement of phytochrome A and cryptochrome 1 in the immediate response after the onset of light period, and phytochrome B in the synchronization of flower opening and closure to the light cycles.
