Potassium Flux and Leaf Movement in Samanea saman
Samanea leaflets usually open in white light and fold together when darkened, but also open and dose with a circadian rhythm during prolonged darkness. Leaflet movement results from differential changes in the turgor and shape of motor cells on opposite sides of the pulvinus; extensor cells expand during opening and shrink during closure, while flexor cells shrink during opening and expand duri...
متن کاملAn Overview on the Biological Perspectives of Samanea Saman (jacq.)merr (rain Tree)
The ancient Indian systems of medicine (AYUSH – Ayurveda, Yunani and Siddha) had explored many medicinal plants which can cure many diseases. The extracts of the medicinal plants possess remarkable biological perspectives. Rain tree (Samanea saman) is one of the tropical tree which possess a wide variety of pharmacological activities. The size of the rain tree generally attains maximum height o...
متن کاملUltra-structural studies on root nodules of Samanea saman (Jacq.) Merr. (Leguminosae).
Ultra-structural studies were conducted on root nodules of Samanea saman (Jacq.) Merr. collected from trees growing under natural conditions. Nodules were distributed singly as well as in clusters on the main and lateral roots. Mature nodules were elongated, branched and coralloid. Root hair curling was found but infection threads could not be observed. Rhizobia entered through the epidermis an...
متن کامل12-hydroxyjasmonic acid glucoside is a COI1-JAZ-independent activator of leaf-closing movement in Samanea saman.
Jasmonates are ubiquitously occurring plant growth regulators with high structural diversity that mediate numerous developmental processes and stress responses. We have recently identified 12-O-β-D-glucopyranosyljasmonic acid as the bioactive metabolite, leaf-closing factor (LCF), which induced nyctinastic leaf closure of Samanea saman. We demonstrate that leaf closure of isolated Samanea pinna...
متن کاملPlasma membrane aquaporins in the motor cells of Samanea saman: diurnal and circadian regulation.
Leaf-moving organs, remarkable for the rhythmic volume changes of their motor cells, served as a model system in which to study the regulation of membrane water fluxes. Two plasma membrane intrinsic protein homolog genes, SsAQP1 and SsAQP2, were cloned from these organs and characterized as aquaporins in Xenopus laevis oocytes. Osmotic water permeability (P(f)) was 10 times higher in SsAQP2-exp...
