aminophosphonate-induced changes of betacyanine and ionic efflux.betacyanine and ionic leakage from red beet (beta vulgaris ssp. l. rapacea) roots and lilac (syringa vulgaris l.) leaves under the influence of new aminophosphonates were studied by spectroscopic and conductometric methods. it was found that the leakage of dye or electrolytes depended both on the concentration of the compounds used and their structural features. the results compared to those obtained for the well known herbicide buminafos (dibutyl 1-butylamino-1-cyclohexanephosphonate) enabled t ...201211421448
efficacy of treatment with verbascoside, biotechnologically produced by syringa vulgaris plant cell cultures in an experimental mice model of spinal cord trauma.in this study we evaluated the effect of glycosylated phenylpropanoid verbascoside (vb), isolated from cultured cells of the medicinal plant syringa vulgaris (oleaceae) in experimental animal model of spinal cord injury (sci). sci was induced by the application of vascular clips to the dura via a four-level t5-t8 laminectomy. sci in mice resulted in severe trauma characterized by edema, tissue damage, and apoptosis. at 1 and 6 h after injury, the mice were treated with vb extract, administered a ...201020799028
genome-driven investigation of compatible solute biosynthesis pathways of pseudomonas syringae pv. syringae and their contribution to water stress tolerance.the foliar pathogen pseudomonas syringae pv. syringae exhibits an exceptional ability to survive on asymptomatic plants as an epiphyte. intermittent wetting events on plants lead to osmotic and matric stresses which must be tolerated for survival as an epiphyte. in this study, we have applied bioinformatic, genetic, and biochemical approaches to address water stress tolerance in p. syringae pv. syringae strain b728a, for which a complete genome sequence is available. p. syringae pv. syringae b72 ...201020581190
effects of verbascoside biotechnologically produced by syringa vulgaris plant cell cultures in a rodent model of colitis.the aim of the present study was to examine the effects of verbascoside (vb) in rats subjected to experimental colitis. colitis was induced in rats by intracolonic instillation of 2,4 dinitrobenzene sulfonic acid (dnbs; 25 mg/rat). vb was administered daily per os (0.2 and 2 mg/kg) 4 days after dnbs administration in the colon. treatment with vb significantly (p < 0.01) reduced macroscopic damage score, loss of body weight, myeloperoxidase activity and thiobarbituric acid-reactant substances. mo ...200919242677
antifeedants and feeding stimulants in bark extracts of ten woody non-host species of the pine weevil, hylobius abietis.bark of ten woody species, known to be rejected as a food source by the pine weevil, hylobius abietis, were sequentially extracted by a soxhlet apparatus with pentane followed by methanol. species were alder (alnus glutinosa), aspen (populus tremula), beech (fagus sylvatica), guelder rose (viburnum opulus), holly (ilex aquifolium), horse chestnut (aesculus hippocastanum), lilac (syringa vulgaris), spindle tree (evonymus europaeus), walnut (juglans regia), and yew (taxus baccata). bark of each sp ...200818719963
molecular mechanisms underlying wound healing and anti-inflammatory properties of naturally occurring biotechnologically produced phenylpropanoid glycosides.two phenylpropanoid glycosides, verbascoside (vb) and teupolioside (tp), produced biotechnologically by syringa vulgaris and ajuga reptans plant cell cultures, were studied in vitro and in vivo for their anti-inflammatory and wound healing activities. it was shown that tp- and vb-containing extracts significantly accelerated wound healing and possessed remarkable anti-inflammatory action in the excision wound model. these effects correlated with the inhibition of reactive oxygen species release ...200717543237

phenological modifications in plants by various edaphic factors.various mechanical, chemical and physical soil analyses were carried out, in addition to weather observations, for 3 years at several sites along an oceanic-continental gradient in a fjord district in western norway. all the environmental factors observed were correlated with the spring and a few late-season phenophases of many native and cultivated woody plants and some herbs by simple, linear correlations and by stepwise multiple and partial analyses. different techniques were used to try and ...200111769320
the main allergen of olea europaea (ole e i) is also present in other species of the oleaceae family.three major pollen allergens from fraxinus excelsior, ligustrum vulgare and syringa vulgaris belonging to the oleaceae family were purified. monoclonal antibodies previously raised against the main allergen of olea europaea (ole e i) were used for their purification by affinity chromatography. the three new purified allergens were able to bind human ige from serum of olive-allergic patients in a way analogous to ole e i. crossed radioimmunoelectrophoresis of the four allergens, using anti-olive ...19938319129
role of auxin and sucrose in the differentiation of sieve and tracheary elements in plant tissue cultures.the differentiation of sieve and tracheary elements was studied in callus culture of daucus carota l., syringa vulgaris l., glycine max (l.) merr., helianthus annuus l., hibiscus cannabinus l. and pisum sativum l. by the lacmoid clearing technique it was found that development of the phloem commenced before that of the xylem. in not one of the calluses was differentiation of tracheary elements observed in the absence of sieve elements. the influence of indole-3-acetic acid (iaa) and sucrose was ...198024306691
floral to green: mating switches moth olfactory coding and preference.mating induces profound physiological changes in a wide range of insects, leading to behavioural adjustments to match the internal state of the animal. here, we show for the first time, to our knowledge, that a noctuid moth switches its olfactory response from food to egg-laying cues following mating. unmated females of the cotton leafworm (spodoptera littoralis) are strongly attracted to lilac flowers (syringa vulgaris). after mating, attraction to floral odour is abolished and the females fly ...201222319127
phenological observations on shrubs to predict weed emergence in turf.phenology is the study of periodic biological events. if we can find easily recognizable events in common plants that precede or coincide with weed emergences, these plants could be used as indicators. weed seedlings are usually difficult to detect in turf, so the use of phenological indicators may provide an alternative approach to predict the time when a weed appears and consequently guide management decisions. a study was undertaken to determine whether the phenological phases of some plants ...200515846520
