(family: leguminosae) on ccl(4) (carbon tetrachloride) treated oxidative stress in wistar albino rats. ccl(4) injection induced oxidative stress by a significant rise in serum glutamate oxaloacetate transaminases (sgot), serum glutamate pyruvate transaminases (sgpt), lactate dehydrogenase (ldh) and thiobarbituric acid reactive substances (tbars) along with reduction of superoxide dismutase (sod), catalase (cat), ...200716930896
broom and honeybees in australia: an alien liaison.facilitative interactions between non-indigenous species are gaining recognition as a major driver of invasion success. cytisus scoparius (l.) link (fabaceae), or scotch broom, is a cosmopolitan invasive shrub that lacks the capacity for vegetative reproduction and is a good model to study facilitative interactions. its success in pioneer environments is determined by constraints on its reproduction. we determined whether pollinators were required for seed set in c. scoparius at barrington tops, ...200516163620
unexpectedly diverse mesorhizobium strains and rhizobium leguminosarum nodulate native legume genera of new zealand, while introduced legume weeds are nodulated by bradyrhizobium species.the new zealand native legume flora are represented by four genera, sophora, carmichaelia, clianthus, and montigena. the adventive flora of new zealand contains several legume species introduced in the 19th century and now established as serious invasive weeds. until now, nothing has been reported on the identification of the associated rhizobia of native or introduced legumes in new zealand. the success of the introduced species may be due, at least in part, to the nature of their rhizobial sym ...200415466541
impacts of a native parasitic plant on an introduced and a native host species: implications for the control of an invasive weed.while invasive species may escape from natural enemies in the new range, the establishment of novel biotic interactions with species native to the invaded range can determine their success. biological control of plant populations can be achieved by manipulation of a species' enemies in the invaded range. interactions were therefore investigated between a native parasitic plant and an invasive legume in mediterranean-type woodlands of south australia.200919001426
galactose-binding lectins as markers of pregnancy-related glycoproteins.protein extracts from pregnant mouse endometria were compared with those obtained from non-pregnant and pseudopregnant mice to detect early pregnancy-specific galactose-rich glycoproteins. gradient gel electrophoresis combined with lectin overlay and lectin histochemistry were used to identify ricinus communis i (rca-i), r. communis ii (rca-ii) and cytisus scoparius (csa) lectin binding glycoproteins. using this approach, galactose-rich glycoproteins were identified that were maximally expressed ...19938468198
bioremediation of polluted soil through the combined application of plants, earthworms and organic matter.two plant species (paulownia tomentosa and cytisus scoparius), earthworms (eisenia fetida), and organic matter (horse manure) were used as an ecological approach to bioremediate a soil historically contaminated by heavy metals and hydrocarbons. the experiment was carried out for six months at a mesoscale level using pots containing 90 kg of polluted soil. three different treatments were performed for each plant: (i) untreated planted soil as a control (c); (ii) planted soil + horse manure (20:1 ...201222911348
volatile fingerprints of seeds of four species indicate the involvement of alcoholic fermentation, lipid peroxidation, and maillard reactions in seed deterioration during ageing and desiccation stress.the volatile compounds released by orthodox (desiccation-tolerant) seeds during ageing can be analysed using gas chromatography-mass spectrometry (gc-ms). comparison of three legume species (pisum sativum, lathyrus pratensis, and cytisus scoparius) during artificial ageing at 60% relative humidity and 50 °c revealed variation in the seed volatile fingerprint between species, although in all species the overall volatile concentration increased with storage period, and changes could be detected pr ...201223175670

cytisus scoparius (fam. fabaceae) in southern brazil - first step of an invasion process?the occurrence of scotch broom cytisus scoparius (l.) link (fabaceae), is reported for the first time in brazil. the species has been registered in the species-rich campos sulinos grasslands, in the campos de cima da serra, and in the serra do sudeste. naturalizing populations were frequently formed in natural habitats near to human settlements, where prevailing land uses and disturbances facilitate dispersal and establishment. the plant is an invasive species that has globally caused significan ...201626871495
introduced scotch broom (cytisus scoparius) invades the genome of native populations in vulnerable heathland habitats.cytisus scoparius is a global invasive species that affects local flora and fauna at the intercontinental level. its natural distribution spans across europe, but seeds have also been moved among countries, mixing plants of native and non-native genetic origins. hybridization between the introduced and native gene pool is likely to threaten both the native gene pool and the local flora. in this study, we address the potential threat of invasive c. scoparius to local gene pools in vulnerable heat ...201627105397
reconstructing pedigrees using probabilistic analysis of issr amplification.data obtained from issr amplification may readily be extracted but only allows us to know, for each gene, if a specific allele is present or not. from this partial information we provide a probabilistic method to reconstruct the pedigree corresponding to some families of diploid cultivars. this method consists in determining for each individual what is the most likely couple of parent pair amongst all older individuals, according to some probability measure. the construction of this measure bear ...201727678162
influence of the drying method in the antioxidant potential and chemical composition of four shrubby flowering plants from the tribe genisteae (fabaceae).flowers from several common mediterranean shrubs, such as those from the cytisus genus and genista genus (tribe genisteae/fabaceae) have long been used for medicinal purposes and seasoning in the northeastern portuguese region. despite, the shade-drying traditionally used to process these plants, freeze-drying is claimed to better preserve the quality of medicinal plants. herein, the effects of drying process in the antioxidants composition and properties of cytisus multiflorus, cytisus scopariu ...201121816201
snowpack, fire, and forest disturbance: interactions affect montane invasions by non-native shrubs.montane regions worldwide have experienced relatively low plant invasion rates, a trend attributed to increased climatic severity, low rates of disturbance, and reduced propagule pressure relative to lowlands. manipulative experiments at elevations above the invasive range of non-native species can clarify the relative contributions of these mechanisms to montane invasion resistance, yet such experiments are rare. furthermore, global climate change and land use changes are expected to cause decr ...201525482316
structural differences between two lectins from cytisus scoparius, both specific for d-galactose and n-acetyl-d-galactosamine.three lectin fractions were obtained from seeds of the leguminous plant cytisus scoparius (scotch broom) by means of affinity chromatography on a n-acetyl-d-galactosamine medium. the first fraction, termed csia, was equally well inhibited in haemagglutination experiments by d-galactose and by n-acetyl-d-galactosamine and consisted of a group of isolectins formed from closely related polypeptide chains of approx. mr 30000. the second fraction, csib, was closely related to csia in specificity, c.d ...19846477513

the primary structure of the cytisus scoparius seed lectin and a carbohydrate-binding peptide.the complete amino acid sequence of 2-acetamido-2-deoxy-d-galactose-binding cytisus scoparius seed lectin ii (csii) was determined using a protein sequencer. after digestion of csii with endoproteinase lys-c or asp-n, the resulting peptides were purified by reversed-phase high performance liquid chromatography (hplc) and then subjected to sequence analysis. comparison of the complete amino acid sequence of csii with the sequences of other leguminous seed lectins revealed regions of extensive hom ...19921429525
protein bodies from the cotyledons of cytisus scoparius l. (link). ultrastructure, isolation, and subunit composition of albumin, legumin and vicilin.the structure of protein bodies differs in the upper and lower parts of the cotyledons of mature seeds of cytisus scoparius l. the palisade-mesophyll cells contain essentially homogeneous protein bodies, without globoids, but the protein bodies of the spongy-mesophyll cells are heterogeneous, with numerous globoids. albumins, legumins and vicilins were selectively extracted from isolated protein bodies and their subunits separated by sds-page, under non-reducing and reducing conditions.198524241309
cellular localization of quinolizidine alkaloids by laser desorption mass spectrometry (lamma 1000).stem sections of lupinus polyphyllus and cytisus scoparius have been analyzed for the distribution of quinolizidine alkaloids by laser desorption mass spectrometry, employing a lamma 1000 instrument. sparteine and lupanine could be recorded and were found to be restricted to the epidermis and probably also to the neighbouring 1 or 2 subepidermal cell layers.198424253573
testing the role of genetic factors across multiple independent invasions of the shrub scotch broom (cytisus scoparius).knowledge of the introduction history of invasive plants informs on theories of invasiveness and assists in the invasives management. for the highly successful invasive shrub scotch broom, cytisus scoparius, we analysed a combination of nuclear and chloroplast microsatellites for eight native source regions and eight independent invasion events in four countries across three continents. we found that two exotic australian populations came from different sources, one of which was derived from mul ...200717908215
projecting rates of spread for invasive species.all else being equal, the faster an invading species spreads, the more dangerous its invasion. the projection of spread rate therefore ought to be a central part of the determination of invasion risk. originally formulated in the 1970s to describe the spatial spread of advantageous alleles, integrodifference equation (ide) models have since been co-opted by population biologists to describe the spread of populations. more recently, they have been modified to include population structure and envi ...200415357802
