Most leguminous plants close their leaves in the evening, as if to sleep, and open them early in the morning. This circadian rhythm is known to be controlled by the biological clock of such plants. Extensive studies on other nyctinastic plants led to

Allelochemicals were isolated from the germinating maize (zea mays L.) seeds in order to know the allelopathic constituents in the plants at the early developmental stage. Three allelochemicals were found in the acetone extract obtained from the meso

cis-p-Coumaroylagmatine (1) was isolated from Albizzia julibrissin Durazz, a nyctinastic plant, as a leaf-opening substance. The compound was quite effective for opening the plant leaves at 5×10(-6) M at night, but was not effective for other nyctin

Electrochemical bromination of germacrene D 1 and geraniol 2 carrying plural olefinic bonds provided the corresponding brominated products 3–10. The bicyclic derivative 6 was preferentially produced from 1, while chemical brominations provided no c

Circadian rhythmic plant leaf movement, called nyctinasty, is controlled by a time-course change in the internal concentration of the leaf-movement factor in the plant body. We report that specific binding protein (210 and 180 kDa) for a leaf-movemen

The conformation of the 11-membered ring of the lathyrane skeleton has been investigated using NMR spectra and theoretical calculations. Some other skeletons, such as jatrophane, jatrapholane, and tigliane, seem to be derived from this framework, and

Albiziahexoside (1), a new hexaglycosylated saponin, was isolated from leaves of Albizzia lebbeck. Saponin 1, which is an analog of cytotoxic albiziatrioside A (2), did not show cytotoxicity. However, 1 is a potential source of 2 and related bioactiv

Nyctinasty has been known since pre-Christian era, whereas the question ‘Why do leguminous plants sleep?’ has always puzzled scientists. This paper gives a clue to the historical mystery: by using synthetic inhibitors for nyctinasty, we found tha

There are fewer weeds in the ground covered with pinecones of Japanese red pine trees (Pinus densiflora Sieb. et Zucc.) than in the ground without pinecones. When six species of seeds were cultured with Japanese red pinecones on agar, the growth of c
