Temperature sensing: A potassium channel as cold sensor in the rain tree Samanea saman [PDF]
Current Biology, 2023 The rain tree Samanea saman folds its leaves upon rainfall. New results now indicate that rain perception is in fact a temperature-sensing process, and that Samanea possess an ion channel with a strong temperature sensitivity that is involved in leaf movement.

Light-stimulated inositolphospholipid turnover in Samanea saman leaf pulvini [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1987 Leaflets of Samanea saman open and close rhythmically, driven by an endogenous circadian clock. Light has a rapid, direct effect on the movements and also rephases the rhythm. We investigated whether light signals might be mediated by increased inositolphospholipid turnover, a mechanism for signal transduction that ...

12-Hydroxyjasmonic acid glucoside causes leaf-folding of Samanea saman through ROS accumulation [PDF]
Scientific Reports, 2022 Foliar nyctinasty, a circadian rhythmic movement in plants, is common among leguminous plants and has been widely studied. Biological studies on nyctinasty have been conducted using Samanea saman as a model plant.

Potassium Channels in Motor Cells of Samanea saman [PDF]
Plant Physiology, 1988 Leaflet movements in Samanea saman are driven by the shrinking and swelling of cells in opposing (extensor and flexor) regions of the motor organ (pulvinus). Changes in cell volume, in turn, depend upon large changes in motor cell content of K(+), Cl(-) and other ions.

New Triterpenoid Glycosides from the Stem Bark of Samanea Saman
International Journal of Basic Sciences and Applied Computing, 2020 From the stem bark of Samanea saman two new triterpenoid glycoside have been isolated and characterized as 3, 22 – dihydroxyolean -12-ene-24-0--D-xylopyranoside 1 and 1, 2, 3-trihydroxy-16-0-acetylolean-12-ene-28-oic-0 [--Darabinopyranosyl (13)] --D-arabinopyranoside 2 by spectral and chemical studies.

Ion Channels Regulate Nyctinastic Leaf Opening in Samanea saman [PDF]
Current Biology, 2018 The circadian leaf opening and closing (nyctinasty) of Fabaceae has attracted scientists' attention since the era of Charles Darwin. Nyctinastic movement is triggered by the alternate swelling and shrinking of motor cells at the base of the leaf. This, in turn, is facilitated by changing osmotic pressures brought about by ion flow through anion and ...

In vitro evaluation of antagonism by Trichoderma spp. towards Phellinus noxius associated with rain tree ( Samanea saman ) and Senegal mahogany ( Khaya senegalensis ) in Singapore [PDF]
Plant Physiology, 2017 The movement of Samanea leaflets depends upon changes in the curvature of the pulvinus at the base of each leaflet. Pulvinar bending and straightening, in turn, are driven by the movement of water between opposing (extensor and flexor) sides of the pulvinus. Although water movement depends on water potential (Psi) and thus on osmotic potential (pi) and
