rapid hydropassive opening and subsequent active stomatal closure follow heat-induced electrical signals in mimosa pudica.	in mimosa pudica l., heat stimulation triggers leaflet folding in local, neighbouring and distant leaves. stomatal movements were observed microscopically during this folding reaction and electrical potentials, chlorophyll fluorescence, and leaf co(2)/h(2)o-gas exchange were measured simultaneously. upon heat stimulation of a neighbouring pinna, epidermal cells depolarized and the stomata began a rapid and pronounced transient opening response, leading to an approximately 2-fold increase of stom ...	2006	16698819
effects of ethephon, 1-aminocyclopropane-1-carboxylic acid, and inhibitors of ethylene synthesis on the gravitropically induced movement of mimosa pudica pulvinus.	primary pulvini of mimosa pudica l. displaced from their position display gravitropic movements beginning about 15 minutes after their reorientation. ethephon, an ethylene-releasing compound, and 1-aminocyclopropane-1-carboxylic acid, an intermediate in ethylene biosynthesis, enhance these movements at a concentration as low as 10 nanomolar. inhibitors of ethylene synthesis (l-alpha-(2-aminoethoxyvinyl)glycine, (aminooxy)acetic acid, and co(2+)) reduce the amplitude of the movements. the promoti ...	1985	16664163
inhibition of photosynthesis by ethylene-a stomatal effect.	ethylene at hormonally significant levels inhibited net photosynthesis of the cultivated peanut (arachis hypogaea l.) as measured by gas analysis. upon the removal of ethylene, the inhibition was naturally overcome at the concentration-exposure duration combinations tested. increased length of exposure of 1 microliter of ethylene per liter of air up to 6 hours increased the degree of net photosynthesis inhibition (68% reduction after 6-hour exposure). significantly greater inhibition of photosyn ...	1982	16662540
effects of lanthanum and ethylenediaminetetraacetate on leaf movements of mimosa.	lanthanum and ethylenediaminetetraacetate (edta) profoundly affect the rapid leaf movements of mimosa pudica l. lanthanum, which mimics calcium but does not penetrate the plasmalemma, inhibits the closing response but does not affect reopening. a low concentration of edta retards the reopening process while a higher edta concentration prevents the closing movement. there is evidence that the edta effects result from chelation of calcium ions rather than chelation of other cations. these results ...	1977	16660153
contractile characteristics of mimosa pudica l.	the force-velocity characteristics of the primary pulvinus of mimosa pudica have been determined using a new polytonic measurement technique. the contractile characteristics were determined from a modified form of hill's equation (hill, a. v. 1938. proc. roy. soc. london b126: 136-195) describing the physiological contractile behavior of animal muscle. the values of the resulting hill's constants were found to be remarkably similar to those of intact animal muscle and reconstituted contractile c ...	1975	16659326
migration of calcium and its role in the regulation of seismonasty in the motor cell of mimosa pudica l.	volume and conformational changes of the contractile tannin vacuoles of the abaxial motor cells of the primary pulvinus of mimosa pudica l. parallel the seismonastic leaf movement. since such changes in cells and organelles of animal systems are often regulated by calcium, we studied ca(2+) movement in the motor cells and tissue. by fixation with lillie's neutral buffered formalin, followed by staining with alizarin red sulfate (ars), calcium was localized in the tannin vacuoles of the motor cel ...	1972	16657899
mechanism of the seismonastic reaction in mimosa pudica.	the efflux of k(+) from the pulvinar cells of mimosa pudica was shown to increase substantially during the seismonastic reaction. this result is shown to indicate a decrease in sigma (reflection coefficient) of pulvinar cell membrane for potassium salts which could account for the pulvinar cell turgor decrease during the seismonastic reaction.membrane potentials and concentrations of ca(2+), k(+), cl(-), s, and p were measured in the top and bottom halves of pulvini. pulvinar cells showed a larg ...	1969	16657174
phytochrome effects in the nyctinastic leaf movements of albizzia julibrissin and some other legumes.	participation of phytochrome is evident in the nyctinastic response of leaves of albizzia julibrissin (silk-tree), albizzia lophantha, leucaena glauca, poinciana gilliesi and calliandra inequilatera; closure of excised pairs of pinnules upon darkening is rapid following red illumination and slow following far-red. under good conditions the difference is obvious within 10 minutes. these observations confirm a report by fondeville, borthwick, and hendricks on the sensitive plant, mimosa pudica, bu ...	1967	16656671

leaf folding in a sensitive plant: a defensive thorn-exposure mechanism?	quantitative photographic evidence is presented indicating that in the sensitive plant schrankia microphylla the leaf-folding response that accompanies the sensitive reaction results in a pronounced increase in thorn exposure. it is argued that in sensitive plants that are thorny, including other species of schrankia, as well as mimosa pudica, the plant in which the sensitive reaction is traditionally demonstrated, leaf folding may be a defensive adaptation.	1981	16592957
early changes in membrane permeability, production of oxidative burst and modification of pal activity induced by ergosterol in cotyledons of mimosa pudica.	ergosterol (a fungal membrane component) was shown to induce transient influx of protons and membrane hyperpolarization in cotyledonary cells of mimosa pudica l. by contrast, chitosan (a fungal wall component with known elicitor properties) triggered membrane depolarization. in the processes induced by ergosterol, a specific desensitization was observed, since cells did not react to a second ergosterol application but did respond to a chitosan treatment. this comparative study correspondingly sh ...	2006	16510520
change in the actin cytoskeleton during seismonastic movement of mimosa pudica.	the seismonastic movement of mimosa pudica is triggered by a sudden loss of turgor pressure. in the present study, we compared the cell cytoskeleton by immunofluorescence analysis before and after movement, and the effects of actin- and microtubule-targeted drugs were examined by injecting them into the cut pulvinus. we found that fragmentation of actin filaments and microtubules occurs during bending, although the actin cytoskeleton, but not the microtubules, was involved in regulation of the m ...	2006	16489209
coexistence of burkholderia, cupriavidus, and rhizobium sp. nodule bacteria on two mimosa spp. in costa rica.	rrna gene sequencing and pcr assays indicated that 215 isolates of root nodule bacteria from two mimosa species at three sites in costa rica belonged to the genera burkholderia, cupriavidus, and rhizobium. this is the first report of cupriavidus sp. nodule symbionts for mimosa populations within their native geographic range in the neotropics. burkholderia spp. predominated among samples from mimosa pigra (86% of isolates), while there was a more even distribution of cupriavidus, burkholderia, a ...	2006	16461667
from semi-conductors to the rhythms of sensitive plants: the research of j.c. bose.	j.c. bose (1858-1937) was one of the world's first biophysicists. he was the first person to use a semi conducting crystal to detect radio waves, and the ingenious inventor of a portable apparatus for generating and detecting microwaves (approximately 1 cm to 5 mm radio waves, frequency 12-60 ghz), as well as inventing many instruments now routinely used in microwave technology. bose extended his specialist knowledge of the physics of electromagnetic radiation into insightful experiments on the ...	2005	16359611
mimosine, a toxin present in leguminous trees (leucaena spp.), induces a mimosine-degrading enzyme activity in some rhizobium strains.	thirty-seven rhizobium isolates obtained from the nodules of leguminous trees (leucaena spp.) were selected on the basis of their ability to catabolize mimosine, a toxin found in large quantities in the seeds, foliage, and roots of plants of the genera leucaena and mimosa. a new medium containing mimosine as the sole source of carbon and nitrogen was used for selection. the enzymes of the mimosine catabolic pathway were inducible and were present in the soluble fraction of the cell extract of in ...	1994	16349454
