does the invasive lupinus polyphyllus increase pollinator visitation to a native herb through effects on pollinator population sizes?	invasive plants may compete with native species for abiotic factors as light, space and nutrients, and have also been shown to affect native pollination interactions. studies have mainly focused on how invasive plants affect pollinator behaviour, i.e. attraction of pollinators to or away from native flowers. however, when an invasive plant provides resources utilized by native pollinators this could increase pollinator population sizes and thereby pollination success in natives. effects mediated ...	2014	24061551

multilocus sequence analysis of bosea species and the description of bosea lupini sp. nov., bosea lathyri sp. nov., and bosea robiniae sp. nov. isolated from legumes in flanders (belgium).	gram-negative, rod-shaped bacteria were isolated from lupinus polyphyllus, lathyrus latifolius and robinia pseudoacacia root nodules. based on the 16s rrna gene phylogeny, they were closely related to bosea species (100 - 97%), belonging to the alphaproteobacteria class and bradyrhizobiaceae family. the closest relative for lmg 26383t, lmg 26379t and lmg 26381t were respectively, bosea thiooxidans (99.6%), bosea eneae (98.3%) and bosea minatitlanensis (99.0%). chemotaxonomic data, including the ...	2011	22155761
zoospore interspecific signaling promotes plant infection by phytophthora.	oomycetes attack a huge variety of economically and ecologically important plants. these pathogens release, detect and respond to signal molecules to coordinate their communal behaviors including the infection process. when signal molecules are present at or above threshold level, single zoospores can infect plants. however, at the beginning of a growing season population densities of individual species are likely below those required to reach a quorum and produce threshold levels of signal mole ...	2010	21138563
differential consumption of four aphid species by four lady beetle species.	the acceptability of four different aphid species macrosiphum albifrons (essig), macrosiphum euphorbiae (thomas), macrosiphum pseudorosae patch, and myzus persicae (sulzer) (hemiptera: aphididae), as prey for four lady beetle species, one native species coccinella trifasciata l, and three non-native coccinella septempunctata l, harmonia axyridis pallas, propylea quatuordecimpunctata l (coleoptera: coccinellidae) were tested in the laboratory. the relative field abundance of adults of the same la ...	2010	20578952
role of myzus persicae (hemiptera: aphididae) and its secondary hosts in plum pox virus propagation.	plum pox virus (family potyviridae, genus potyvirus, ppv) is one of the most important viral pathogens of plants in the genus prunus, particularly prunus persica l. the role of the myzus persicae (sulzer) (hemiptera: aphididae) as a vector of ppv-m, and its role in spreading ppv-m, was investigated. ppv-m-infected peach trees were used as inoculum sources, and transmission to 15 herbaceous species commonly present in and around peach orchards was evaluated. the presence of ppv-m in secondary hos ...	2007	17849850
characterisation and expression of monosaccharide transporters in lupins, lupinus polyphyllus and l. albus.	monosaccharide transporter (mst) genes of lupinus polyphyllus and l. albus were cloned, expressed and characterised. the isolation and functional characterisation of a cdna clone and its corresponding genomic clone of a sugar transporter from l. polyphyllus (lpstp1) is reported. phylogenetic comparison of the nucleic and amino acid sequences showed the highest similarity to the atstp1 gene from arabidopsis thaliana, which encodes a high affinity sugar transporter. the similar topology as well as ...	2007	17882353
molecular cloning of a cdna for the ubiquitin gene of lupinus polyphyllus.		2002	2173830
study of structure--hepatoprotective relationships of oleanene-type triterpenoidal glucuronides obtained from several fabaceous plants on rat primary hepatocyte cultures.	the protective effects of nine oleanene-type triterpenoidal glucuronides obtained from several fabaceous plants (lupinus polyphyllus x arboreus hybrid, astragalus complanatus, wistaria brachybotrys) on in vitro immunological liver injury in primary cultured rat hepatocytes were studied. although all tested saponins showed hepatoprotective action, the levels of activity of the individual saponins differed. structure-activity relationships for the sapogenol moiety suggested that the presence of th ...	1999	10077443
complete elimination of hostplant quinolizidine alkaloids by larvae of a polyphagous lycaenid butterfly, callophrys rubi.	caterpillars of the lycaenid butterfly callophrys rubi accept a variety of hostplants. when fed inflorescences or leaves of genista tinctoria (a natural hostplant) or lupinus polyphyllus (a non-host), the larvae completely eliminate quinolizidine alkaloids ingested from their food in their frass. no alkaloids are stored. infestation by the parasitoid wasp distatrix sancus (braconidae) did not affect alkaloid elimination. the presence of an effective anti-toxin system is discussed with reference ...	1993	28313683
direct observation of cell wall structure in living plant tissues by solid-state c nmr spectroscopy.	solid-state (13)c nuclear magnetic resonance (nmr) spectra of the following intact plant tissues were recorded by the crosspolarization magic-angle spinning technique: celery (apium graveolens l.) collenchyma; carob bean (ceratonia siliqua l.), fenugreek (trigonella foenum-graecum l.), and nasturtium (tropaeolum majus l.) endosperm; and lupin (lupinus polyphyllus lindl.) seed cotyledons. all these tissues had thickened cell walls which allowed them to withstand the centrifugal forces of magic an ...	1990	16667266
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.	1984	24253573
activation of chloroplast-localized enzymes of quinolizidine alkaloid biosynthesis by reduced thioredoxin.	previous studies from the laboratory of the authors have shown that the tetracyclic quinolizidine alkaloids are synthesized in leaf chloroplasts of lupinus polyphyllus. additionally, alkaloid formation reveals a light dependent diurnal rhythm in vivo. the present study shows that the principal biosynthetic enzymes, lysine decarboxylase and 17-oxosparteine synthase, assayed in acetone powder extracts and isolated chloroplasts of l. polyphyllus, were activated by reduced e. coli thioredoxin. since ...	1981	24258744
