Outline of Final Research Achievements

Soy bean, one of the major leguminous plants, are widely recognized to exert sleep-movement rhythm. In this study, we evaluated the relationship between biological functions and its sleep-movements, and obtained the following results. (1) soy bean leaf indicated clear sleep-movement rhythm, (2) antioxidant activity was stimulated the beginning of dark period, (3) gene expression of LUX indicated typical diurnal rhythm, (4) isoflvone amounts decreased at ZT6, and (5) gene expression of C4H concerning isoflavone synthesis reached at maximum at ZT6 in a legume.
