the phenology of rubus fruticosus in ireland: herbarium specimens provide evidence for the response of phenophases to temperature, with implications for climate warming.to date, phenological research has provided evidence that climate warming is impacting both animals and plants, evidenced by the altered timing of phenophases. much of the evidence supporting these findings has been provided by analysis of historic records and present-day fieldwork; herbaria have been identified recently as an alternative source of phenological data. here, we used rubus specimens to evaluate herbaria as potential sources of phenological data for use in climate change research an ...201222382508
identification of cyanidin 3-o-β-(6″-(3-hydroxy-3-methylglutaroyl)glucoside) and other anthocyanins from wild and cultivated blackberries.anthocyanins from blackberries are natural dietary pigments. the aim of this study was to investigate the occurrence of anthocyanins in fruits of wild norwegian blackberries and three blackberry ( rubus fruticosus l.) cultivars and to report the complete identification of cyanidin 3-o-β-(6″-(3-hydroxy-3-methylglutaroyl)glucopyranoside), 5. this new pigment is most probably the same pigment that has previously been reported to occur in various blackberry samples as cyanidin 3-dioxalylglucoside. a ...201121635009
membrane binding sites for the human blood group h-type 2 determinant, an inducer of laminarinase activity in protoplasts of rubus fruticosus l.the human blood-group determinants h-type 1 (α-l-fuc-(1 → 2)-β-d-gal-(1 → 3)β-d-glcnac), or type 2 (α-l-fuc(1 → 2)-β-d-gal(1 → 4)-β-d-glcnac) and their mono- and disaccharidic precursors, have been reported to induce d-glycanase (laminarinase) activity in rubus cells (y. liénart et al. 1990, plant science 68, 197-202) and protoplasts (y. liénart et al. 1991, plant science 77, 41-45). using immunoadsorbent h-type 1 as a matrix for the affinity purification of membrane proteins, and the h-type 2 t ...199224178382
structural features and biological activity of xyloglucans from suspension-cultured plant cells.different xyloglucan (xg) fractions were isolated from rubus fruticosus cells cultured in suspension. sequential extraction showed that two distinct xyloglucans existed in the primary walls. the first could be easily extracted in alkali and the second was tightly associated to cellulose. a third fraction was isolated from the extracellular polysaccharides of the culture medium. the alkali-soluble xg and the extracellular xg showed many structural features in common. by use of an anti-xg polyclon ...19921576212
burrowing, feeding, egestion and energy budgets of allolobophora rosea (savigny) (lumbricidae).allolobophora rosea (savigny) was found to be common in mull type soils beneath bramble (rubus fruticosus l.). burrow construction in this soil type in the laboratory at 4.4, 10.0 and 14.8°c ranged between 133 and 516 mm g-1 fresh wt of worm day-1. burrowing was affected by both body size and temperature. rates of soil displacement during burrowing were estimated from burrowing rates, burrow dimensions and soil density; depending on body size and temperature they were in the range 809-1,928 mg d ...197628308928
structural characterization by (13)c-nmr spectroscopy of products synthesized in vitro by polysaccharide synthases using (13)c-enriched glycosyl donors: application to a udp-glucose:(1-->3)-beta-d-glucan synthase from blackberry (rubus fruticosus).a simple and sensitive method for the characterization of products synthesized in vitro by polysaccharide synthases is described. it relies on the use of (13)c-enriched nucleotide sugars as substrates and on the analysis of the newly synthesized polysaccharides by (13)c-nuclear magnetic resonance (nmr) spectroscopy. the method was validated with a (1-->3)-beta-d-glucan synthase from blackberry, but it may be applied to the study of any glycosyltransferase. the chemical synthesis of udp-d-[u-(13) ...200415159383
hyaluronidase inhibitory activity from the polyphenols in the fruit of blackberry (rubus fruticosus b.).the hyaluronidase inhibitory activity of different fractions obtained from aqueous extract of blackberry fruits was evaluated. we found that only fractions f3 and f7 inhibit the tested enzyme.200212490243
intraplant distribution of acalitus essigi (acari: eriophyoidea) on blackberries (rubus fruticosus agg.).specialised phytophagous arthropods often display high levels of specificity to particular sites on their host plant. in this paper we examine the occupation of microhabitats and aggregation patterns of the eriophyoid mite, acalitus essigi (hassan), on its host plant, european blackberry (rubus fruticosus l. aggregate), a plant that undergoes significant seasonal changes in its morphology. a. essigi was found to be a refuge inhabiting species. it resided in bud and leaf axil microhabitats on bot ...200112171272
in vitro versus in vivo cellulose microfibrils from plant primary wall synthases: structural differences.detergent extracts of microsomal fractions from suspension cultured cells of rubus fruticosus (blackberry) were tested for their ability to synthesize in vitro sizable quantities of cellulose from udp-glucose. both brij 58 and taurocholate were effective and yielded a substantial percentage of cellulose microfibrils together with (1-->3)-beta-d-glucan (callose). the taurocholate extracts, which did not require the addition of mg(2+), were the most efficient, yielding roughly 20% of cellulose. th ...200212145282
characterization of the binding of alpha-l-fuc (1-->2)-beta-d-gal (1-->), a xyloglucan signal, in blackberry protoplasts.previous work showed that the fucose-->galactose moiety of the xyloglucan nonasaccharide xxfg is responsable for its biological activity. we used this side chain of xxfg (alpha-l-fuc (1-->2)-beta-d-gal (1-->)) in ligand-binding experiments to demonstrate its role as a signal molecule in plant cells. proteins solubilized from plasma membrane enriched fractions isolated from rubus fruticosus protoplasts were tested for their ability to bind the side chain of xxfg, using a digoxigenin- or biotin-co ...200010808074
xyloglucan octasaccharide xxlgol derived from the seeds of hymenaea courbaril acts as a signaling moleculetreatment of the xyloglucan isolated from the seeds of hymenaea courbaril with humicola insolens endo-1,4-beta-d-glucanase i produced xyloglucan oligosaccharides, which were then isolated and characterized. the two most abundant compounds were the heptasaccharide (xxxg) and the octasaccharide (xxlg), which were examined by reference to the biological activity of other structurally related xyloglucan compounds. the reduced oligomer (xxlgol) was shown to promote growth of wheat (triticum aestivum) ...19989501133
two rhamnogalacturonide tetrasaccharides isolated from semi-retted flax fibers are signaling molecules in rubus fruticosus l. cells.water extraction of semi-retted flax (linum usitatissimum l.) fiber bundles yielded a mixture of pectic oligosaccharides and two acidic rhamnogalacturonide tetrasaccharides that were separated by size-exclusion chromatography. one- and two-dimensional nuclear magnetic resonance studies and fast atom bombardment-mass spectrometry experiments indicated that the two tetrasaccharides have a common primary structure, i.e. alpha-d-delta galpa(1-->2)-alpha-l- rhap(1-->4)-alpha-d-galpa-(1-->2)-l-alpha,b ...19979342877
changes in wall-bound polysaccharidase activities during the culture cycle of a rubus fruticosus cell suspension.several hydrolytic enzyme activities were detected in the wall of developing cells of rubus fruticosus in suspension culture. the corresponding substrates of the enzymes are mostly polysaccharide wall constituents, except for chitinase activity. the activities measured when the enzymes were in the free state or wall-bound showed the positive influence of the cell wall micro-environment. changes in the activities during a cell culture cycle demonstrated that those enzymes acting on xyloglucans be ...19958789344
application of dna fingerprinting to the taxonomy of european blackberry species.thousands of blackberry species (rubus subgenus rubus) have been described from central and northern europe. these species are usually polyploid and pseudogamous. since apomixis is only facultative, the species have retained the possibility to produce some offspring by sexual recombination. hybridization of restriction-enzyme-digested dna samples to the m13, (ac)/(tg) and 33.15 probes has yield valuable information on the occurrence and distribution of genetic variation in rubus. intraspecific v ...19958582363
