| soil-to-plant transfer of native selenium for wild vegetation cover at selected locations of the czech republic. | total selenium (se) contents were determined in aboveground biomass of wild plant species growing in two uncultivated meadows at two different locations. the soils in these locations had pseudototal (aqua regia soluble) se in concentration ranges of between 0.2 and 0.3 mg kg(-1) at the first location, and between 0.7 and 1.4 mg kg(-1) at the second location. the plant species represented 29 plant families where the most numerous ones were poaceae, rosaceae, fabaceae , and asteraceae. the seleniu ... | 2015 | 25975239 |
| the influence of goutweed (aegopodium podagraria l.) tincture and metformin on the carbohydrate and lipid metabolism in dexamethasone-treated rats. | diabetes mellitus and metabolic syndrome are the common problems of the modern society. the interest in herbal medicines increases, and often they are used in combination with conventional drugs. aegopodium podagraria l. (goutweed) is a plant widely used in traditional medicine. hypoglycemic effect of goutweed aerial part tincture has been previously shown in alloxan-induced diabetic mice and in rats receiving excess of fructose and hydrochlorothiazide. the effects of co-administration of the ti ... | 2016 | 27450405 |
| transcriptome analysis of invasive plants in response to mineral toxicity of reclaimed coal-mine soil in the appalachian region. | efficient postmining reclamation requires successful revegetation. by using rna sequencing, we evaluated the growth response of two invasive plants, goutweed (aegopodium podagraria l.) and mugwort (artemisia vulgaris), grown in two appalachian acid-mine soils (ms-i and -ii, ph ∼ 4.6). although deficient in macronutrients, both soils contained high levels of plant-available al, fe and mn. both plant types showed toxicity tolerance, but metal accumulation differed by plant and site. with ms-i, al ... | 2015 | 26269111 |
| geographic and habitat origin influence biomass production and storage translocation in the clonal plant aegopodium podagraria. | through physiological integration, clonal plants can support ramets in unfavourable patches, exploit heterogeneously distributed resources and distribute resources that are taken up over large areas. physiological integration generally increases in adverse conditions, but it is not well known which factors determine the evolution of physiological integration. the aim of this study was to investigate if clonal plants from southern and northern populations of the clonal herb aegopodium podagraria ... | 2014 | 24427305 |
| temperature requirements differ for the two stages of seed dormancy break in aegopodium podagraria (apiaceae), a species with deep complex morphophysiological dormancy. | only a few studies have considered the possibility that low temperature requirements may vary among stages of dormancy break in seeds with morphophysiological dormancy (mpd). we show that this lack of consideration in previous studies on seed dormancy and germination of aegopodium podagraria might explain the low germination percentages and/or the relatively long periods of incubation needed for germination. under natural temperatures, embryos began to grow in september and were fully elongated ... | 2009 | 21628259 |
| the polyacetylene falcarindiol with cox-1 activity isolated from aegopodium podagraria l. | extracts of aegopodium podagraria l. were screened in vitro for cyclooxygenase-1 (cox-1) inhibitory activity. the isolation of the active compound falcarindiol was achieved by bioassay-guided fractionation. the identification of the active compound was confirmed by (1)h nmr and (13)c nmr. the ic(50)-value of falcarindiol was 0.3 microm in the cox-1 assay. a quantitative determination of the seasonal variation in the content of falcarindiol in different plant parts was carried out by hplc analysi ... | 2007 | 17574359 |
| in situ observation of stomatal movements and gas exchange of aegopodium podagraria l. in the understorey. | observations of stomata in situ while simultaneously measuring co(2) gas exchange and transpiration were made in field experiments with aegopodium podagraria in a highly variable light climate in the understorey of trees. the low background photosynthetic photon flux density (ppfd) caused a slight opening of the stomata and no visible response to sporadic lightflecks. however, if lightflecks were frequent and brighter, slow opening movements were observed. small apertures were sufficient to allo ... | 2000 | 11053464 |
| a bioassay using artemia salina for detecting phototoxicity of plant coumarins. | artemia salina (brine shrimp) has been successfully used for toxicity testing, and a screening test for phototoxicity has been developed based on this method. the ability of the method to test the phototoxic potential of seven known compounds was investigated. athamantin (an angular furanocoumarin) and umbelliferone (a simple coumarin) showed no phototoxicity, while linear furanocoumarins exhibited phototoxic activity in the following order: psoralen > bergapten > peucedanin > xanthotoxin. the a ... | 1999 | 10630112 |
| ribosome-inactivating lectins with polynucleotide:adenosine glycosidase activity. | lectins from aegopodium podagraria (apa), bryonia dioica (bda), galanthus nivalis (gna), iris hybrid (ira) and sambucus nigra (snai), and a new lectin-related protein from sambucus nigra (snlrp) were studied to ascertain whether they had the properties of ribosome-inactivating proteins (rip). ira and snlrp inhibited protein synthesis by a cell-free system and, at much higher concentrations, by cells and had polynucleotide:adenosine glycosidase activity, thus behaving like non-toxic type 2 (two c ... | 1997 | 9188793 |
| interspecies differences in the preference of ammonium and nitrate in vascular plants. | three solution experiments were performed to test the importance of nh 4(+) versus no 3(-) +nh 4(+) to growth of 23 wild-forest and open-land species, using field-relevant soil solution concentrations at ph 4.5. at n concentrations of 1-200 μm growth increased with increasing n supply in carex pilulifera, deschampsia flexuosa, elymus caninus and bromus benekenii. geum urbanum was the most n demanding species and had little growth below 200 μm. the preference for nh 4(+) or no 3(-) +nh 4(+) was t ... | 1995 | 28306841 |
| indication of transthylakoid proton-fluxes in aegopodium podagraria l. by light-induced changes of plasmalemma potential, chlorophyll fluorescence and light-scattering. | the time course of the responses of chlorophyll fluorescence in leaves of aegopodium podagraria to changes in irradiance does not necessarily show the time constant of thylakoid energization at energy fluence rates below 10-25 w·m(-2). in addition, other measures of thylakoid energization, such as lightscattering at 532 nm and the responses to saturating flashes, show that the related component disappears from these signals at low fluence rates, but not necessarily all together at the same fluen ... | 1988 | 24220863 |
| electron-microscopic analysis of ground elder (aegopodium podagraria l.) lectin: evidence for a new type of supra-molecular protein structure. | the lectin of ground elder (aegopodium podagraria l.) was investigated electron-microscopically after negative staining with uranyl salts. affinity-purified preparations of this glycoprotein were highly heteromorphous as they contained small particles approximately 4.6 nm in diameter and very large particles of different shapes. among the latter, circular and helicoidal structures were the most regular in appearance. the circles were 9.3 nm in diameter, whereas the helices were 9 nm or 20 nm in ... | 1987 | 24225783 |
| soil acidification and vegetation changes in deciduous forest in southern sweden. | thirtyfour deciduous forest sites in southern sweden, originally studied in 1949-1970, were resampled in 1984/85. the average ph change in the humus layer was-0.78 and-0.23 in soils originally studied 30-35 and 15-20 years ago, respectively. cover changes in the field layer were measured and related to ph changes. the number of species had increased in spite of ph decreases, reaching a maximum at ph 4.0-5.0, while the total cover of the field layer was unchanged.two groups of species showed no c ... | 1986 | 28311918 |
| isolation and partial characterization of a lectin from ground elder (aegopodium podagraria) rhizomes. | a lectin has been isolated from rhizomes of ground elder (aegopodium podagraria) using a combination of affinity chromatography on erythrocyte membrane proteins immobilized on cross-linked agarose and hydroxyapatite, and ion-exchange chromatography. the molecular structure of the lectin was determined by gelfiltration, sucrose density-gradient centrifugation and gel electrophoresis under denaturing conditions. it has an unusually high mr (about 480000) and is most probably an octamer composed of ... | 1985 | 24249502 |
