| Outline of Final Research Achievements |
Periodical plants repeat mass flowering and withering at a species-specific interval more than one year. Strobilanthes flexicaulis (Acanthaceae) is a periodical plant that repeats mass flowering every six years in Okinawa Island, Japan. S. flexicaulis may have a biological clock measuring six years from germination to flowering, because they flower and wither in the sixth year from their germination. In this study, we explored periodical genes measuring six years by comparisons with non-periodical relative species, and performed cultivation experiments controlling cultivation environments. The cultivation experiments suggested that air temperature is an important signal to count time from germination to flowering.
