effect of elevated tropospheric ozone on the structure of bacterial communities inhabiting the rhizosphere of herbaceous plants native to germany.current elevated concentrations of ozone in the atmosphere, as they are observed during summer seasons, can cause severe effects on plant vegetation. this study was initiated to analyze whether ozone-stressed plants also transfer signals below ground and thereby alter the bacterial community composition in their rhizospheres. herbaceous plants, native to germany, with tolerance (anthoxanthum odoratum, achillea millefolium, poa pratensis, rumex acetosa, and veronica chamaedrys) and sensitivity (m ...200516332747
solid-phase microextraction of volatile components from natural grassland plants.the volatile components from nine plants growing on natural grasslands in auvergne, central france, selected for the broad qualitative and quantitative diversity of their terpenoid fractions, were analyzed by high-resolution gas-phase chromatography and mass spectrometry (hrgc-ms) after static headspace solid-phase microextraction (shs-spme). shs-spme allowed all the plant material to be analyzed under the same conditions despite its wide-ranging composition. this is not always possible with oth ...200111170578

growth and nutritive quality of poa pratensis as influenced by ozone and competition.interspecific plant competition has been hypothesized to alter effects of early-season ozone (o3) stress. a phytometer-based approach was utilized to investigate o3 effects on growth and nutritive quality of poa pratensis grown in monoculture and in mixed cultures with four competitor-plant species (anthoxanthum odoratum, achillea millefolium, rumex acetosa and veronica chamaedrys). mesocosms were exposed during april/may 2000-2002 to charcoal-filtered air+25 ppb o3 (control) or non-filtered air ...200616290915
alpha-peroxyachifolid and other new sensitizing sesquiterpene lactones from yarrow (achillea millefolium l., compositae).yarrow, achillea millefolium l., is one of the commonest weeds of the compositae family. cases of allergic contact dermatitis have been described since 1899. although 10 sesquiterpene lactones (sl) and 3 polyines have previously been identified, the sensitizers of yarrow have escaped detection. a reinvestigation of short ether extracts of yarrow revealed the presence of 5 unsaturated hitherto unknown guaianolides of peroxide character. the main sl, identified as a strong sensitizer in guinea pig ...19911868717
prehibernation diet and reproductive condition of female anopheles messeae in sweden.1. blood and sugar feeding in the mosquito anopheles messeae falleroni were investigated near uppsala, sweden, from 1981 to 1985, with emphasis on prehibernation diet. 2. fructose, indicating plant feeding, was present in females of all ovarian stages, from april to october, and contributed to fat body development in non-gonoactive females before hibernation. 3. an.messeae males and females (inseminated and uninseminated) were observed feeding on floral nectaries of the plants achillea millefoli ...19911768915
repelling properties of some plant materials on the tick ixodes ricinus l.the repellent effects on nymphal stages of ixodes ricinus l. of some plant materials have been studied in the laboratory. the plant material consisted of an ethanolic extract from achillea millefolium l., and volatile oils of birch and/or pine tar, citronella, cloves, eucalyptus, geranium, lavender, lily of the valley and peppermint. the most pronounced effects were observed for the oils of citronella, cloves and lily of the valley. they possessed repelling activities of the same magnitude as th ...200616360943
physiological and biochemical stress responses in grassland species are influenced by both early-season ozone exposure and interspecific competition.the effects of two-year early season ozone exposure on physiological and biochemical stress response were investigated in model plant communities. achillea millefolium and veronica chamaedrys target plants were grown in monocultures and in mixed cultures with poa pratensis (phytometer) and exposed in open-top chambers over two years for five weeks to charcoal-filtered (cf) air plus 25 nl l(-1) o3 (control) and non-filtered (nf) air plus 50 nl l(-1) o3. significant o3 effects were detected in dif ...200616321463
in vitro susceptibility of helicobacter pylori to botanical extracts used traditionally for the treatment of gastrointestinal disorders.the gram-negative bacterium helicobacter pylori (hp), identified in 1982, is now recognized as the primary etiological factor associated with the development of gastritis and peptic ulcer disease. in addition, hp infections are also associated with chronic gastritis, gastric carcinoma and primary gastric b-cell lymphoma. for centuries, herbals have been used in traditional medicine to treat a wide range of ailments, including gastrointestinal (gi) disorders such as dyspepsia, gastritis and pepti ...200516317658

preliminary screening study of reproductive outcomes after exposure to yarrow in the pregnant rat.yarrow (achillea millefolium) is used for the treatment of diarrhea, as a urinary antiseptic, hypotensive, and diuretic. yarrow also has traditionally been used as an abortifacient, emmenagogue, contraceptive, and for stimulating uterine contractions. for this reason, it is contra-indicated for use in pregnancy. there has, however, been little scientific research carried out to either confirm or refute this recommendation.200314745991
legume presence increases photosynthesis and n concentrations of co-occurring non-fixers but does not modulate their responsiveness to carbon dioxide enrichment.legumes, with the ability to fix atmospheric nitrogen (n), may help alleviate the n limitations thought to constrain plant community response to elevated concentrations of atmospheric carbon dioxide (co(2)). to address this issue we assessed: (1) the effects of the presence of the perennial grassland n(2 )fixer, lupinus perennis, on biomass accumulation and plant n concentrations of nine-species plots of differing plant composition; (2) leaf-level physiology of co-occurring non-fixing species (a ...200312802677
