| bacteria within ovules and seeds. | surface-sterilized ovules and seeds of 27 species of plants were cultured in the water of syneresis of a nutrient medium low in agar content. bacteria were obtained from 30% of the ovules, 15% of the seeds of herbaceous plants, 16% of the seeds of woody plants, 5.4% of the overwintered noncereal seeds, and 13.5% of overwintered cereal seeds. in no instance did every ovule or seed of a plant species contain bacteria. no bacteria were obtained from the hard, waxy seeds of mimosa or yellowwood. the ... | 1976 | 984839 |
| the use of tannin from chestnut (castanea vesca). | after mimosa and quebracho extracts, chestnut extract is the third most important vegetable tannin used for leather production. it is produced only in europe on the northern side of the mediterranean sea. the extract is prepared by hot water extraction of the bark and timber, followed by spray-drying of the solution. analysis shows that there are insignificant variations in extract quality between batches, so the extract can be used with modern automated leather production systems. the extract c ... | 1992 | 1417692 |
| pollen allergy to mimosa (acacia floribunda) in a mediterranean area: an occupational disease. | we have described respiratory allergy to the pollens of mimosa (acacia floribunda) in some mediterranean areas of italy and france. the incidence of sensitivity is only 1.2% in a population of atopics but 31% in an "at risk" population of floriculturists. it seems, therefore, that the pollen of acacia floribunda, although heavy and amphiphilous, is potentially allergenic for subjects who are in close proximity. | 1991 | 2006774 |
| experimental evaluation of mimosa tenuiflora (willd.) poir. (tepescohuite) i. screening of the antimicrobial properties of bark extracts. | mimosa tenuiflora (willd.) poir, is a tree from the south areas of mexico. this bark is popularly used as remedy to treat different skin lesions. the present study demonstrates the in vitro antimicrobial properties of the water and ethanolic extracts prepared with the dried and powdered bark of this plant. a clear inhibition growth effect was observed in all the gram positive and gram negative organisms, yeasts and dermatophytes used. | 1989 | 2764672 |

| 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 |

| mimosine blocks cell cycle progression by chelating iron in asynchronous human breast cancer cells. | mimosine is a toxic nonprotein amino acid that is a major constituent of the tropical legumes leucaena and mimosa. mimosine has been shown to cause acute and chronic toxicosis in livestock fed from forage containing these plants. recently, mimosine has been demonstrated to reversibly block cell cycle progression in mammalian cells in culture. in this study, we compared the effects of mimosine to desferrioxamine (dfo), a well-characterized iron chelator, and found that both chemicals similarly al ... | 1996 | 8806853 |

| image management in pacs: how should they be decomposed into well-defined and interoperable industrial products? | we consider that no consensus currently exists on how pacs should be decomposed into well-defined and interoperable industrial products. we believe that this lack of consensus hampers the development of multi-vendor pacs and makes the standardization process slower. this paper tries to understand the ins and outs of these choices. to realize this we have used the mimosa functional model (euripacs project) as a reference model. we have then delineated the borders between several possible industri ... | 1997 | 9509402 |

| endemic mimosa species can serve as mycorrhizal "resource islands" within semiarid communities of the tehuacán-cuicatlán valley, mexico. | this paper explores if mimosa species (fabaceae-mimosoideae) can serve as arbuscular mycorrhizal (am) and nutrient "resource islands" in six plant communities in the semiarid valley of tehuacán-cuicatlán, mexico. spatial heterogeneity related to the occurrence of mimosa species results in temporal differences in am-fungal spore numbers and soil nutrients. a higher number of am-fungal spores were found in the soil below the canopies of six endemic mimosa species than in the soil from non-vegetate ... | 2003 | 12836080 |
| 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 |

| excitable cells in mimosa. | by inserting microelectrodes into cells of various tissues, it was shown that elongated parenchyma cells in the phloem and protoxylem, which have larger membrane potential than inexcitable cells of other types, generate action potentials with conduction. the electrical features of these cells are essentially similar to those of nerve and muscle cells. | 1962 | 13912476 |
| 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 |
| legume symbiotic nitrogen fixation by beta-proteobacteria is widespread in nature. | following the initial discovery of two legume-nodulating burkholderia strains (l. moulin, a. munive, b. dreyfus, and c. boivin-masson, nature 411:948-950, 2001), we identified as nitrogen-fixing legume symbionts at least 50 different strains of burkholderia caribensis and ralstonia taiwanensis, all belonging to the beta-subclass of proteobacteria, thus extending the phylogenetic diversity of the rhizobia. r. taiwanensis was found to represent 93% of the mimosa isolates in taiwan, indicating that ... | 2003 | 14645288 |
| rhizobium etli bv. mimosae, a novel biovar isolated from mimosa affinis. | fifty rhizobial isolates from root nodules of mimosa affinis, a small leguminous plant native to mexico, were identified as rhizobium etli on the basis of the results of pcr-rflp and rflp analyses of small-subunit rrna genes, multilocus enzyme electrophoresis and dna-dna homology. they are, however, a restricted group of lineages with low genetic diversity within the species. the isolates from m. affinis differed-from the r. etli strains that orginated from bean plants (phaseolus vulgaris) in th ... | 1999 | 10555329 |

| 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 |

| 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 |
