| 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 |
| 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 |

| thigmomorphogenesis: the response of plant growth and development to mechanical stimulation : with special reference to bryonia dioica. | when young plants of hordeum vulgare. bryonia dioica. cucumis sativus. phaseolus vulgaris. mimosa pudica. and ricinus communis. were given a gentle mechanical stimulus by rubbing the internodes for about 10 s once or twice daily, elongation was significantly retarded. plants of cucurbita pepo pisum sativum and triticum aestivum did not exhibit any such response. the initial response to rubbing was very rapid, elongation stopping less than 3 min after application of the stimulus. when the stimulu ... | 1973 | 24458719 |
| 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 |

| 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 |
| [mimosa pudica adenosine triphosphatase]. | the morphological structure (pulvinus p1, p2 and p3) directly involved in the seismonastic movements of the mimosa pudica leaf have been used to isolate: 1) "soluble" atpase, loosely bound to pulvinus structures; 2) ca, mg-dependent atpase, which is tightly bound to pulvinus structures and is extracted by a saline solution of high ionic strength, used to isolate actomyosin from muscles and non-muscle motile cells; 3) atpase bound to the pulvinus membrane structures, which is solubilized by the d ... | 1978 | 148923 |
| calcium and potassium in the motor organ of the sensitive plant: localization by ion microscopy. | the ion microscope was used to study potassium and calcium distributions in the main motor organ of mimosa pudica l. the cortex of the motor organ has two cell types differing in location, structure, and ion distribution. histochemical features portrayed in ion micrographs were plainly correlated with structures seen in the light and electron microscopes. | 1979 | 17738090 |

| 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 |
| folklore information from assam for family planning and birth control. | the author collected folklore information on herbal treatments to control fertility from different parts of assam, india. temporary methods of birth control include cissampelos pareira l. in combination with piper nigrum l., root of mimosa pudica l. and hibiscus rosa-sinensis l. plants used for permanent sterilization include plumbago zeylanica l., heliotropium indicum l., salmalia malabrica, hibiscus rosa-sinensis l., plumeria rubra l., bambusa rundinacea. abortion is achieved through use of ... | 1982 | 12266264 |
| 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 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 |
| mimosine content of leucaena leucocephala and the sensitivity of rhizobium to mimosine. | mimosine was qualitatively and quantitatively estimated from the different parts of leucaena leucocephala strains k-8 and k-67. the amount of mimosine as percentage of dry weight in the two strains were, respectively, as follows: seeds, 6.82, 9.98; old leaves, 1.5, 1.33; young leaves, 2.85, 3.33; main root, 1.13, 1.02; lateral roots, 1.46, 1.17; stems, 0.73, 0.33. rhizobium isolates from l. leucocephala (uas-ll-8, uas-ll-67), mimosa pudica (uas-mp) and prosopis juliflora (uas-pj) formed an effec ... | 1985 | 23195805 |

| biochemical mechanisms and effects of mimosa pudica (linn) on experimental urolithiasis in rats. | urolithiasis, following implantation of zn discs in urinary bladder (foreign body insertion technique), was examined in albino rats of either sex. marked variation was observed between sex, regarding the formation of bladder stones. ethylene glycol (1%) mixed in drinking water for 4 weeks, was unable to augment zn disc-induced stone deposition. chemical nature of stones was identified as of magnesium ammonium phosphate type. neither urinary ph nor infection in the urinary bladder/tract affected ... | 1990 | 2365419 |
| inactivation of strongyloides stercoralis filariform larvae in vitro by six jamaican plant extracts and three commercial anthelmintics. | in vitro bioassay of (a) aqueous methanol extracts (ame) of the green leaves of mimosa (mimosa pudica), love weed (cuscuta americana), vervine (stachytarpheta jamaicensis), chicken weed (salvia serotina) and breadfruit (artocarpus altilis); (b) methanol-water fraction (mwf) of breadfruit leaves, and (c) commercially available drugs albendazole, thiabendazole and levamisole were assayed for nematode inactivating potential, using filariform larvae of strongyloides stercoralis. test larvae were obt ... | 1990 | 2082565 |
| a novel tubulin from mimosa pudica. purification and characterization. | from mimosa pudica fresh leaves and pulvinar callus cells, we have purified tubulin protein using an anion-exchange resin, deae-sephadex a-50, followed by ammonium sulfate fractionation and sephadex g-200 gel filtration. the purified protein consisted of alpha and beta subunits and trace quantities of other proteins. when analysed by sodium dodecyl sulfate/polyacrylamide gel electrophoresis at ph 8.8, both alpha and beta subunits of tubulin almost comigrated with their counterparts from goat bra ... | 1990 | 2209590 |
| sulfhydryl groups of mimosa pudica tubulin implicated in colchicine binding and polymerization in vitro. | the important characteristic of novel mimosa pudica tubulin is its ability to bind colchicine only when dithiothreitol is included in the isolation buffer, indicating the involvement of sulfhydryl groups in colchicine binding. modification of sulfhydryl groups by a sulfhydryl modifying agent also affects the normal assembly of tubulin into microtubules, as revealed by electron microscopic and spectrophotometric studies. the number of free sulfhydryl groups present in tubulin protein responsible ... | 1992 | 1567190 |
| cold stability of microtubules of mimosa pudica. | the unique property of mimosa pudica microtubules is that they are cold stable in nature. they do not dissociate at 0 degrees c unlike animal microtubules. no other protein fractions of m. pudica are responsible for the cold-resistance property of these microtubules. it seems that tubulin, itself, has an intrinsic cold resistance which makes it unique compared with animal tubulin. moreover, m. pudica microtubule makes cold-sensitive goat brain microtubule cold-resistant when used in greater than ... | 1993 | 8485459 |
| [immobilization of a sensitive plant, mimosa pudica l., by volatile anesthetics]. | the disappearance of thigmonastic mobility of a sensitive plant, mimosa pudica l., caused by volatile anesthetic agents such as methoxyflurane, chloroform, halothane, enflurane or sevoflurane revealed that the response to anesthetic agents in plants maybe similar to that in animals. in terms of reversible anesthesia, animals seem to equal plants in order of potency of anesthetics, and the minimum immobilizing concentration (mic; %) in the plant shows a good correlation with mac in the human (mic ... | 1993 | 8366560 |
| plasmalemmal, voltage-dependent ionic currents from excitable pulvinar motor cells of mimosa pudica. | plasmalemmal ionic currents from excitable motor cells of the primary pulvinus of mimosa pudica were investigated by patch-clamp techniques. in almost all of the enzymatically isolated protoplasts, a delayed rectifier potassium current was activated by depolarization, while no currents were detected upon hyperpolarization. this sustained outward current was reversibly blocked by ba and tea and serves to repolarize the membrane potential. outward single channel currents that very likely underly t ... | 1993 | 7684082 |
| c-glycosoylflavones from aerial parts of mimosa pudica. | 1994 | 17236039 | |
| calcium-sensitivity of the plasmalemmal delayed rectifier potassium current suggests that calcium influx in pulvinar protoplasts from mimosa pudica l. can be revealed by hyperpolarization. | isolated protoplasts from pulvinar motor cells of mimosa pudica were studied using conventional whole-cell patch clamp techniques. with internal solutions weakly buffered for ca2+ (0.2 mm egta), a rundown of the outward delayed rectifier k+ current was induced by hyperpolarizing the holding potential, and this effect was strongly promoted by high external ca2+ concentrations. this rundown could be reversed by coming back to less hyperpolarized holding potentials or by lowering the external [ca2+ ... | 1995 | 7473689 |
| vibriocidal activities of some local herbs. | four of the seven tested medicinal plants exhibited antimicrobial activity against vibrio cholerae. these 7 plants are: ficus capensis, mitragyna stipulosa, entada africana, piliostigma reticulatum, terminalia avicennoides, mimosa pudica, and lannea acida. of them terminalia avicennoides showed higher antimocrobial activity than others. potentials of these herbs in the control of cholera need to be determined. | 1995 | 7594314 |
| the enzyme involved in sulfation of the turgorin, gallic acid 4-o-(beta-d-glucopyranosyl-6'-sulfate) is pulvini-localized in mimosa pudica. | a sulfotransferase (st) which catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate (paps) to gallic acid glucoside was characterized from microsomal preparations of mimosa pudica. the product of the reaction was found to co-elute on hplc with the periodic leaf movement factor 1 (plmf-1)(gallic acid beta-d-gluco-pyranosyl-6'-sulfate). the distribution of the enzyme activity was restricted to plasma membrane preparations from primary, secondary and tertiary pulvini. the m. ... | 1997 | 9375396 |
| distribution and activity of the plasma membrane h+-atpase in mimosa pudica l. in relation to ionic fluxes and leaf movements. | plasma membrane h+-atpase was immunolocalized in several cell types of the sensitive plant mimosa pudica l., and transmembrane potentials were measured on cortical cells. in comparison with the nonspecialized cortical cells of the petiole or stem, the proton pump was highly expressed in motor cells. these immunological data are in close agreement with electrophysiological data, because the active component of the transmembrane potential was low in the nonspecialized cortical cells and high in mo ... | 1997 | 12223640 |
| increased expression of vacuolar aquaporin and h+-atpase related to motor cell function in mimosa pudica l. | mature motor cells of mimosa pudica that exhibit large and rapid turgor variations in response to external stimuli are characterized by two distinct types of vacuoles, one containing large amounts of tannins (tannin vacuole) and one without tannins (colloidal or aqueous vacuole). in these highly specialized cells we measured the abundance of two tonoplast proteins, a putative water-channel protein (aquaporin belonging to the [gamma]-tips [tonoplast intrinsic proteins]) and the catalytic a-subuni ... | 1997 | 12223745 |
| an apyrase from mimosa pudica contains n5,n10-methenyl tetrahydrofolate and is stimulated by light. | an apyrase (ntp/ndpase) implicated in the response of mimosa pudica to stimuli, such as touch, has been cloned, sequenced and expressed in escherichia coli. while purifying and characterizing this enzyme, it was observed that a chromophore is associated with it, having absorption in the ultraviolet-a/blue region of the spectrum. the absorbance maximum of the chromophore, purified from the enzyme complex by gel filtration and hplc, is around 350 nm. the chromophore has been identified as n5,n10-m ... | 1998 | 9990319 |
| mimosa pudica apyrase requires polysaccharide and ca2+ for the activity. | mimosa pudica linn leaves with pulvini contain unique isoforms (i and ii) of apyrase enzyme (ec 3.6.1.5). the activity of isoform i depends on divalent cation mn2+. this isoform is associated noncovalently with the polysaccharide, containing mainly of galactose and arabinose sugars. the apparent molecular mass of these 2 isoforms are 36 and 34 kd respectively. the association of the polysaccharide with the isoform i has been found to be ca2+ dependent which is endogenously present in this isofor ... | 1998 | 9788742 |
| inhalational and local anesthetics reduce tactile and thermal responses in mimosa pudica. | in reaction to a variety of stimuli, the sensitive plant mimosa pudica closes its leaflets and drops its stems. the objective was to investigate the effects of anaesthetics on the reaction of mimosa pudica to a variety of stimuli. | 1999 | 10210057 |
| mimosa pudica may possess antidepressant actions in the rat. | in mexico, aqueous extracts from dried leaves of mimosa puolica are employed to alleviate depression. in this study, the behavioral actions of aqueous extracts of m. pudica at various concentrations were tested. rats having received saline (0.9%; 0.30 ml; i.p.), clomipramine, desipramine or several dosages of aqueous extracts from m. pudica (ml = 2.0 mg/kg; m2 = 4.0 mg/kg; m3 = 6.0 mg/kg; m4 = 8.0 mg/kg) during a 30-day period were submitted to the forced swimming test and to the test for differ ... | 1999 | 11962537 |
| chemistry and biology of plant leaf movements. | the leaves of mimosa pudica l. are well known for their rapid movement when touched. recently, we were able to isolate an excitatory substance in small quantities from this plant, which consists of three different components (potassium l-malate, magnesium trans-aconitate, and dimethylammonium salt). many plants close their leaves in the evening, as if to sleep, and open them early in the morning (nyctinastic leaf movement). this circadian rhythm is known to be controlled by the biological clock ... | 2000 | 10777626 |
| neutralisation of lethality, myotoxicity and toxic enzymes of naja kaouthia venom by mimosa pudica root extracts. | aqueous and alcoholic extracts of dried roots of mimosa pudica were tested for their inhibitory activity on lethality, myotoxicity and toxic enzymes of naja kaouthia venom. the aqueous extract, particularly the normal water extract, displayed a significant inhibitory effect on the lethality, myotoxicity and tested enzyme activities of venom compared with alcoholic extracts. the present finding suggests that aqueous extracts of m. pudica root possess compound(s), which inhibit the activity of cob ... | 2001 | 11282444 |
| the gelsolin/fragmin family protein identified in the higher plant mimosa pudica. | mimosa pudica l. rapidly closes its leaves and bends its petioles downward when mechanically stimulated. it has been suggested that the actin cytoskeleton is involved in the bending motion since both cytochalasin b and phalloidin inhibit the motion. in order to clarify the mechanism by which the actin cytoskeleton functions in the motion, we attempted to find actin-modulating proteins in the m. pudica plant by dnase i-affinity column chromatography. the egta-eluate from the dnase i column contai ... | 2001 | 11481041 |
| effect of mimosa pudica root powder on oestrous cycle and ovulation in cycling female albino rat, rattus norvegicus. | mimosa pudica root powder (150 mg/kg body weight) when administered intragastrically, altered the oestrous cycle pattern in female rattus norvegicus. nucleated and cornified cells were absent in all rats. the smear was characterized by leucocytes only, as in dioestrus, which persisted for 2 weeks. there was a significant reduction in the number of normal ova in rats treated with the root powder compared with the control rats, and a significant increase in the number of degenerated ova. | 2002 | 11933127 |
| profiling and screening analysis of 27 aromatic amino acids by capillary electrophoresis in dual modes. | an efficient capillary electrophoretic (ce) profiling and screening system based on dual modes of capillary zone electrophoresis (cze) and micellar electrokinetic capillary chromatography (mekc) was developed for the simultaneous determination of 23 nonprotein amino acids (npaas) and 4 protein amino acids with aromatic moiety. it involves separation by an uncoated fused-silica capillary under phosphoric acid buffer in cze mode and by another uncoated fused-silica capillary under neutral sodium d ... | 2002 | 11981855 |
| the potential of thai indigenous plant species for the phytoremediation of arsenic contaminated land. | to assess the potential of the native plant species for phytoremediation, plant and soil samples were collected from two areas in thailand that have histories of arsenic pollution from mine tailings. the areas were the ron phibun district (nakorn si thammarat province) and bannang sata district (yala province), and samples were taken in 1998 and 1999 and analysed for total arsenic by atomic absorption spectrophotometry. arsenic concentrations in soil ranged from 21 to 14,000 microg g(-1) in ron ... | 2002 | 12009144 |
| hyperglycemic effect of leaves of mimosa pudica linn. | ethanolic extract of mimosa pudica leaves given by oral route to mice at a dose of 250 mg/kg showed a significant hyperglycemic effect. | 2002 | 12234583 |
| enantioseparation of chiral aromatic amino acids by capillary electrophoresis in neutral and charged cyclodextrin selector modes. | simultaneous enantioseparations of 15 racemic aromatic amino acids and l-mimosine for their chiral discrimination were achieved by neutral selector-modified capillary electrophoresis (ce) and by charged selector-modified ce. among the diverse cyclodextrins (cds) examined, hydroxypropyl (hp)-alpha-cd as the neutral selector and highly sulfated (hs)-gamma-cd as the charged selector provided best chiral environments of different enantioselectivities. fairly good enantiomeric resolutions were achiev ... | 2002 | 12481269 |
| specific perception of ergosterol by plant cells. | ergosterol (a fungal membrane component) induced modification of proton fluxes and membrane hyperpolarization in motor cells of mimosa pudica. these reactions appear specific since they were not induced by the other sterols tested. a specific desensitization was observed, since cells did not react to a second ergosterol application. exposed at first to other sterols, cells remained reactive to ergosterol. comparatively, chitosan (a fungal wall component with known elicitor properties) triggered ... | 2003 | 12876888 |
| nodulation of mimosa spp. by the beta-proteobacterium ralstonia taiwanensis. | several beta-proteobacteria have been isolated from legume root nodules and some of these are thought to be capable of nodulating and fixing n2. however, in no case has there been detailed studies confirming that they are the active symbionts. here, ralstonia taiwanensis lmg19424, which was originally isolated from mimosa pudica nodules, was transformed to carry the green fluorescent protein (gfp) reporter gene before being used to inoculate axenically-grown seedlings of m. pudica and m. diplotr ... | 2003 | 14651338 |
| isolation of fonsecaea pedrosoi from thorns of mimosa pudica, a probable natural source of chromoblastomycosis. | we report the isolation of fonsecaea pedrosoi from thorns of the plant mimosa pudica l. at the place of infection identified by one of our patients. clinical diagnosis of chromoblastomycosis was established by direct microscopic examination and cultures from the patient's lesion. the same species was isolated from the patient and from the plant. scanning electron microscopy of the surface of the thorns showed the characteristic conidial arrangement of f. pedrosoi. these data indicate that m. pud ... | 2004 | 15057332 |
| phylogeny based on 16s rdna and nifh sequences of ralstonia taiwanensis strains isolated from nitrogen-fixing nodules of mimosa pudica, in india. | bacterial symbionts present in the indeterminate-type nitrogen (n)-fixing nodules of mimosa pudica grown in north and south india showed maximum similarity to ralstonia taiwanensis on the basis of carbon-source utilization patterns and 16s rdna sequence. isolates from the nodules of m. pudica from north india and south india showed identical ardra (amplified ribosomal dna restriction analysis) patterns with sau3ai and rsai, but alui revealed dimorphy between the north indian and south indian iso ... | 2004 | 15213739 |
| the multi-protein family of arabidopsis sulphotransferases and their relatives in other plant species. | all members of the sulphotransferase (sot, ec 2.8.2.-) protein family use 3'-phosphoadenosine 5'-phosphosulphate (paps) as the sulphuryl donor and transfer the sulphonate group to an appropriate hydroxyl group of several classes of substrates. these enzymes have highly conserved domains and can be found in eubacteria and eukaryotes. in mammals, sulphate conjugation catalysed by sots constitutes an important reaction in the transformation of xenobiotics, and in the modulation of the biological ac ... | 2004 | 15234990 |
| isolation and anti-fungal activities of 2-hydroxymethyl-chroman-4-one produced by burkholderia sp. mssp. | in the course of screening for biological active compounds from microbial origins, various strains were isolated from roots of mimosa pudica using standard dilution agar plate method. one isolate was selected for further studies of bacterial anti-fungal properties. it was designated mssp and identified as burkholderia sp. by many biological characteristics such as carbohydrate utilization, biochemical and physiological test and 16s rdna sequence homology search. to investigate antagonistic princ ... | 2004 | 15712667 |
| anticonvulsant activity of mimosa pudica decoction. | the decoction of mimosa pudica leaves given intraperitoneally at dose of 1000-4000 mg/kg protected mice against pentylentetrazol and strychnine-induced seizures. m. pudica had no effect against picrotoxin-induced seizures it also antagonized n-methyl-d-aspartate- induced turning behavior. these properties could explain its use in african traditional medicine. | 2004 | 15158987 |
| hyaluronidase and protease activities from indian snake venoms: neutralization by mimosa pudica root extract. | the aqueous root extract of mimosa pudica dose dependently inhibited the hyaluronidase and protease activities of indian snakes (naja naja, vipera russelii and echis carinatus) venom. | 2004 | 15159000 |
| biochemical and immunohistochemical characterization of mimosa annexin. | to characterize the biochemical properties of plant annexin, we isolated annexin from mimosa pudica l. and analyzed the biochemical properties conserved between mimosa annexin and animal annexins, e.g. the ability to bind phospholipid and f-actin in the presence of calcium. we show that mimosa annexin is distributed in a wide variety of tissues. immunoblot analysis also revealed that the amount of annexin is developmentally regulated. to identify novel functions of mimosa annexin, we examined th ... | 2004 | 15168121 |
| proof that burkholderia strains form effective symbioses with legumes: a study of novel mimosa-nodulating strains from south america. | twenty mimosa-nodulating bacterial strains from brazil and venezuela, together with eight reference mimosa-nodulating rhizobial strains and two other beta-rhizobial strains, were examined by amplified rrna gene restriction analysis. they fell into 16 patterns and formed a single cluster together with the known beta-rhizobia, burkholderia caribensis, burkholderia phymatum, and burkholderia tuberum. the 16s rrna gene sequences of 15 of the 20 strains were determined, and all were shown to belong t ... | 2005 | 16269788 |
| 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 |
| beta-rhizobia from mimosa pigra, a newly discovered invasive plant in taiwan. | a total of 191 rhizobial isolates from the root nodules of three geographically separate populations of the invasive plant mimosa pigra in taiwan were examined using amplified rdna restriction analysis, 16s rdna sequences, protein profiles and elisa. of these, 96% were identified as burkholderia and 4% as cupriavidus taiwanensis. the symbiosis-essential genes noda and nifh were present in two strains of burkholderia (pas44 and ptk47), and in one of c. taiwanensis (pas15). all three could nodulat ... | 2005 | 16313648 |
| water channel activities of mimosa pudica plasma membrane intrinsic proteins are regulated by direct interaction and phosphorylation. | cdnas encoding aquaporins pip1;1, pip2;1, and tip1;1 were isolated from mimosa pudica (mp) cdna library. mppip1;1 exhibited no water channel activity; however, it facilitated the water channel activity of mppip2;1 in a phosphorylation-dependent manner. mutagenesis analysis revealed that ser-131 of mppip1;1 was phosphorylated by pka and that cooperative regulation of the water channel activity of mppip2;1 was regulated by phosphorylation of ser-131 of mppip1;1. immunoprecipitation analysis reveal ... | 2005 | 16061230 |
| 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 |
| 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 |
