| purification, characterization, and submitochondrial localization of a 58-kilodalton nad(p)h dehydrogenase. | an nadh dehydrogenase activity from red beet (beta vulgaris l.) root mitochondria was purified to a 58-kd protein doublet. an immunologically related dehydrogenase was partially purified from maize (zea mays l. b73) mitochondria to a 58-kd protein doublet, a 45-kd protein, and a few other less prevalent proteins. polyclonal antibodies prepared against the 58-kd protein of red beet roots were found to immunoprecipitate the nad(p)h dehydrogenase activity. the antibodies cross-reacted to similar pr ... | 1995 | 12228370 |
| characteristics of sucrose transport and sucrose-induced h+ transport on the tonoplast of red beet (beta vulgaris l.) storage tissue. | sucrose-induced changes of the energization state of the red beet root (beta vulgaris l. ssp. conditiva) vacuolar membrane were observed with the fluorescent dyes 6-chloro-9-{[4-(diethylamino)- 1-methylbutyl]-amino}-2-methoxyacridine dihydrochloride, as a ph monitor, and 9-amino-6-chloro-2-methoxyacridine (acma). consequently, transient acidification of the surrounding suspension medium could be measured with a ph electrode. this signal was specific for suc and was not seen for sorbitol, mannito ... | 1995 | 12228372 |
| carbon, nitrogen, and nutrient interactions in beta vulgaris l. as influenced by nitrogen source, no3- versus nh4+ | sugar beets (beta vulgaris l. cv f58-554h1) were grown hydroponically in a 16-h light, 8-h dark period (photosynthetic photon flux density of 0.5 mmol m-2 s-1) for 4 weeks from sowing in half-strength hoagland nutrient solution containing 7.5 mm nitrate. half of the plants were then transferred to 7.5 mm ammonium n; the rest remained in solution with 7.5 mm nitrate n. upon transfer from nitrate to ammonium, the total n concentration decreased sharply in the fibrous roots and petiole/midribs and ... | 1995 | 12228383 |
| leaf phosphate status, photosynthesis, and carbon partitioning in sugar beet (iv. changes with time following increased supply of phosphate to low-phosphate plants). | changes in photosynthesis, carbon partitioning, and growth following resupply of orthophosphate (pi) to moderately p-deficient plants (low-p) were determined for sugar beets (beta vulgaris l. cv f58-554h1) cultured hydroponically in growth chambers. one set of plants was supplied with 1.0 mm pi in half-strength hoagland solution (control plants), and a second set (low-p plants) was supplied with 0.05 mm pi. at the end of 2 weeks, the low-p plants were resupplied with 1.0 mm pi. low-p plants rapi ... | 1995 | 12228438 |
| computer-assisted identification of protoplasts responsible for rare division events reveals guard-cell totipotency. | with the use of a computer-controlled microscope system to assist in the positioning and rapid relocation of large numbers of cultured cells, we were able to identify those protoplasts with the capacity to divide within a highly recalcitrant culture in which only a tiny fraction of the total population proceeds to produce viable microcalli. in the cultures used, comprising beta vulgaris l. (sugar beet) leaf protoplasts, it was confirmed that these cells can be recognized solely on the basis of m ... | 1995 | 12228442 |
| characterization of the red beet plasma membrane h+-atpase reconstituted in a planar bilayer system. | the transport activity of the red beet (beta vulgaris l.) plasma membrane h+-atpase was examined following reconstitution into a planar bilayer membrane. fusion of partially purified plasma membrane h+-atpase with the bilayer membrane was accomplished by perfusion of proteoliposomes against the bilayer under hypoosmotic conditions. following incorporation into the bilayer, an atp-dependent current was measured that demonstrated properties consistent with those of the plasma membrane h+-atpase. c ... | 1995 | 12228483 |
| end-product control of carbon metabolism in culture-grown sugar beet plants (molecular and physiological evidence on accelerated leaf development and enhanced gene expression). | sugar beet (beta vulgaris l.) seedlings were grown on media containing 90 to 300 mm sucrose or glucose. compared to controls, sugar-grown plants had higher growth rate, photosynthesis, and leaf sugar levels. the steady-state level of transcripts increased significantly for the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) (rbcs) and the cytosolic fructose-1,6-bisphosphatase and moderately for the rubisco large subunit (rbcl). the transcript level of sucrose phosphate ... | 1995 | 12228569 |
| purification and characterization of a novel aminopeptidase, plastidial alanine-aminopeptidase, from the cotyledons of etiolated sugar beet seedlings. | during prolonged dark growth of sugar beet (beta vulgaris l.) seedlings, etioplasts, rapidly after the proplastid-etioplast transition, undergo a degenerative process characterized by ultrastructural modifications, protein loss, and the decrease of carotenoid and chlorophyll accumulation upon illumination. two plastidial aminopeptidase activities were identified as early markers of this degenerative process (a. el amrani, i. couee, j.-p. carde, j.-p. gaudillere, p. raymond [1994] plant physiolog ... | 1995 | 12228582 |
| purification and light-dependent molecular modulation of the cytosolic fructose-1,6-bisphosphatase in sugarbeet leaves. | cytosolic fructose-1,6-bisphosphatase (fbpase) was purified 472-fold from sugarbeet (beta vulgaris l.) leaves by ammonium sulfate fractionation, anion-exchange chromatography (deae sepharose), cation-exchange chromatography (s-sepharose), gel filtration (sephacryl s-300), and hydrophobic interaction chromatography (phenyl sepharose). the dissociated polypeptide (molecular mass of 37 kd) was used to generate polyclonal antibodies. western blot analysis revealed a single band that was identified a ... | 1993 | 12231665 |

| characterization of blue-green fluorescence in the mesophyll of sugar beet (beta vulgaris l.) leaves affected by iron deficiency. | the mesophyll of sugar beet (beta vulgaris l.) leaves emits red (chlorophyll a) fluorescence and blue-green fluorescence when excited with ultraviolet light. the intensity of blue-green fluorescence was increased in mesophylls affected by iron deficiency. this increase was large and progressive. it was concomitant with a decrease of photosynthetic pigments per unit of leaf area. most of the increase in blue-green fluorescence can be explained by the decrease of the screening of ultraviolet light ... | 1994 | 12232310 |
| kinetics analysis of the plasma membrane sucrose-h+ symporter from sugar beet (beta vulgaris l.) leaves. | the kinetics behavior of the h+-sucrose (suc) symporter was investigated in plasma membrane vesicles from sugar beet (beta vulgaris l.) leaves by analyzing the effect of external and internal ph (pho and phi, respectively) on suc uptake. the apparent km for suc uptake increased 18-fold as the pho increased from 5.5 to 7.5. over this same pho range, the apparent vmax for suc uptake remained constant. the effects of phi in the presence or absence of internal suc were exclusively restricted to chan ... | 1994 | 12232379 |
| comparison of the stereospecificity and immunoreactivity of nadh-ferricyanide reductases in plant membranes. | the substrate stereospecificity of nadh-ferricyanide reductase activities in the inner mitochondrial membrane and peroxisomal membrane of potato (solanum tuberosum l.) tubers, spinach (spinacea oleracea l.) leaf plasma membrane, and red beetroot (beta vulgaris l.) tonoplast were all specific for the [beta]-hydrogen of nadh, whereas the reductases in wheat root (triticum aestivum l.) endoplasmic reticulum and potato tuber outer mitochondrial membrane were both [alpha]-hydrogen specific. in all is ... | 1994 | 12232391 |
| modifications of etioplasts in cotyledons during prolonged dark growth of sugar beet seedlings (identification of etiolation-related plastidial aminopeptidase activities). | we studied the effects of prolonged dark growth on proplastids and etioplasts in cotyledons of sugar beet (beta vulgaris l.) seedlings. differentiation of proplastids into etioplasts occurred between d 4 and d 6 after imbibition, with the typical characteristics of increased synthesis of plastidial proteins, protein and carotenoid accumulation, size increase, development of plastid membranes and of the prolamellar body, and increase of the greening capacity. however, this situation of efficient ... | 1994 | 12232431 |
| biosynthesis and radical scavenging activity of betalains during the cultivation of red beet (beta vulgaris) hairy root cultures. | betalains biosynthesis and antiradical scavenging activity were investigated during cultivation of four hairy root cultures of beta vulgaris, obtained from different cultivars (bordo, egyptian, detroit 2 and detroit dark red). the best producer of betalains was a hairy root culture from beta vulgaris cv. detroit dark red (13.27 mg/g dry weight total pigment production). the ethanol extract, derived from roots of the same culture grown for 15 days under submerged conditions, showed a high antirad ... | 2009 | 12240990 |
| calcium-activated k+ channels and calcium-induced calcium release by slow vacuolar ion channels in guard cell vacuoles implicated in the control of stomatal closure. | stomatal closing requires the efflux of k+ from the large vacuolar organelle into the cytosol and across the plasma membrane of guard cells. more than 90% of the k+ released from guard cells during stomatal closure originates from the guard cell vacuole. however, the corresponding molecular mechanisms for the release of k+ from guard cell vacuoles have remained unknown. rises in the cytoplasmic ca2+ concentration have been shown to trigger ion efflux from guard cells, resulting in stomatal closu ... | 1994 | 12244253 |
| identification and characterization of high-affinity binding sites for inositol trisphosphate in red beet. | inositol 1,4,5-trisphosphate (insp3) is thought to play a primary role in intracellular ca2+ mobilization during signal transduction in plant cells. although insp3-elicited ca2+ release across the vacuolar membrane has been demonstrated in a variety of species, little is known of the properties of the putative insp3 receptor. using a 3h-insp3 ligand-displacement assay with detergent-solubilized microsomes from the storage root of red beet, we determined that insp3 binds specifically to a single ... | 1993 | 12271091 |

| analysis of nematode-responsive promoters in sugar beet hairy roots. | one of the strategies to make crops resistant to the beet cyst nematode heterodera schachtii is the destruction of the feeding site or syncytium. this can be achieved by local expression of the cytotoxic barnase gene under control of a nematode-inducible plant promoter that is active in the syncytium. expression of barnase outside the feeding site has to be neutralized by its inhibitor barstar driven from a constitutive promoter that is downregulated in the syncytium. several promoters that are ... | 2001 | 12425082 |
| alternate energy-dependent pathways for the vacuolar uptake of glucose and glutathione conjugates. | through the development and application of a liquid chromatography-mass spectrometry-based procedure for measuring the transport of complex organic molecules by vacuolar membrane vesicles in vitro, it is shown that the mechanism of uptake of sulfonylurea herbicides is determined by the ligand, glucose, or glutathione, to which the herbicide is conjugated. atp-dependent accumulation of glucosylated chlorsulfuron by vacuolar membrane vesicles purified from red beet (beta vulgaris) storage root app ... | 2002 | 12428021 |
| a non-modular type b feruloyl esterase from neurospora crassa exhibits concentration-dependent substrate inhibition. | feruloyl esterases, a subclass of the carboxylic acid esterases (ec 3.1.1.1), are able to hydrolyse the ester bond between the hydroxycinnamic acids and sugars present in the plant cell wall. the enzymes have been classified as type a or type b, based on their substrate specificity for aromatic moieties. we show that neurospora crassa has the ability to produce multiple ferulic acid esterase activities depending upon the length of fermentation with either sugar beet pulp or wheat bran substrates ... | 2003 | 12435269 |

| the complete sequence of the rice (oryza sativa l.) mitochondrial genome: frequent dna sequence acquisition and loss during the evolution of flowering plants. | the entire mitochondrial genome of rice (oryza sativa l.), a monocot plant, has been sequenced. it was found to comprise 490,520 bp, with an average g+c content of 43.8%. three rrna genes, 17 trna genes and five pseudo trna sequences were identified. in addition, eleven ribosomal protein genes and two pseudo ribosomal protein genes were found, which are homologous to 13 of the 16 genes for ribosomal proteins in the mitochondrial genome of the liverwort (marchantia polymorpha). a greater degree o ... | 2002 | 12471441 |
| construction of a 'unigene' cdna clone set by oligonucleotide fingerprinting allows access to 25 000 potential sugar beet genes. | access to the complete gene inventory of an organism is crucial to understanding physiological processes like development, differentiation, pathogenesis, or adaptation to the environment. transcripts from many active genes are present at low copy numbers. therefore, procedures that rely on random est sequencing or on normalisation and subtraction methods have to produce massively redundant data to get access to low-abundance genes. here, we present an improved oligonucleotide fingerprinting (ofp ... | 2002 | 12472698 |
| swiss chard: a salad crop for the space program. | salad greens will be among the first crops grown on lunar or planetary space stations. swiss chard (beta vulgaris l.) is an important candidate salad crop because it is high yielding and rich in vitamins and minerals. five swiss chard cultivars were grown in the greenhouse under two light levels for 13 weeks to compare cumulative yields from weekly harvests, mineral composition, and to evaluate sensory attributes as a salad green. the varieties large white ribbed (lwr) and lucullus (luc) were th ... | 2002 | 12481809 |
| modulation of cd8+ intraepithelial lymphocyte distribution by dietary fiber in the rat large intestine. | we studied whether ingestion of dietary fiber modifies the distribution of intraepithelial lymphocytes (iel) in a physiological condition. male wkah rats were fed diets either with fiber (sugar beet fiber or crystalline cellulose, 100 g/kg diet each) or without fiber for 3 weeks. the number of cd8(+), cd4(+), and nkr-p1(+) iel per epithelial layer in the crypt section of the cecum, proximal colon, and distal colon were scored by immunohistochemical staining. we found that the proportion of cd8(+ ... | 2002 | 12486212 |
| the complete nucleotide sequence of beet black scorch virus (bbsv), a new member of the genus necrovirus. | the complete nucleotide sequence of beet black scorch virus (bbsv) was determined. the bbsv genome is composed of 3641 nucleotides and has similar organization with tobacco necrosis virus d of 61% nucleotide identity. the 5'-proximal open reading frame (orf) encodes a putative 23 kda protein and a 82 kda protein by reading-through of an amber termination codon. three small orfs located in the center of the genome may encode for a 4.2 kda protein and two 7 kda proteins. the 3'-proximal orf encode ... | 2002 | 12491108 |
| the mobile bag technique as a method for determining the degradation of four botanically diverse fibrous feedstuffs in the small intestine and total digestive tract of ponies. | an in sacco mobile bag technique was used to determine the rate and extent of disappearance of unmolassed sugar-beet pulp, soyabean hulls, hay cubes and an oat hull-naked oats mixture (67:33, w/w) in the foregut and total digestive tract of ponies. ponies were administered naso-gastrically polyester mesh bags containing 350 mg feed, in a latin square design. bags were collected at the ileo-caecal junction (small intestine bag, sib) and in the faeces (faecal bag, fb) and their residues analysed f ... | 2002 | 12493095 |
| effects of chard (beta vulgaris l. var. cicla) extract on oxidative injury in the aorta and heart of streptozotocin-diabetic rats. | in diabetes mellitus, increased free radical formation raises the incidence of atherosclerosis and cardiovascular diseases. regardless of the type of diabetes, the objective of the therapy is to achieve normoglycemia and to prevent or delay the complications. chard (beta vulgaris l. var. cicla) is used as a hypoglycemic agent by diabetic patients in turkey. the aim of this study was to investigate the effect of feeding chard on diabetes-induced free radical-mediated injury in rat aorta and heart ... | 2002 | 12511111 |
| a host-specific bacteria-to-plant signal molecule (nod factor) enhances germination and early growth of diverse crop plants. | lipo-chitooligosaccharides (lcos), or nod factors, are host-specific bacteria-to-plant signal molecules essential for the establishment of a successful n(2)-fixing legume-rhizobia symbiosis. at submicromolar concentrations nod factors induce physiological changes in host and non-host plants. here we show that the nod factor nod bj v(c18:1,mefuc) of bradyrhizobium japonicum 532c enhances germination of a variety of economically important plants belonging to diverse botanical families: zea mays, o ... | 2003 | 12520335 |
| the companion cell-specific arabidopsis disaccharide carrier atsuc2 is expressed in nematode-induced syncytia. | cyst nematodes induce a metabolically highly active syncytial cell complex in host roots. the syncytia are symplastically isolated. because they form a strong sink, assimilates must be imported via the apoplast, thus suggesting that specific membrane-bound sugar transport proteins are expressed and activated. to identify possible candidate genes, transgenic arabidopsis plants expressing different reporter genes under the control of different promoters from arabidopsis sugar transporter genes wer ... | 2003 | 12529515 |
| adaptation to the digestion of nutrients of a starch diet or a non-starch polysaccharide diet in group-housed pregnant sows. | a trial was conducted with twenty group-housed pregnant sows to study the adaptation in nutrient digestibility to a starch-rich diet or a diet with a high level of fermentable non-starch polysaccharides (nsp) during a time period of 6 weeks. the starch-rich diet was primarily composed of wheat, peas and tapioca, whereas soya bean hulls and sugar beet pulp, which both are highly fermentable nsp sources, were used to formulate the nsp-rich diet. the starch-rich diet and the nsp-rich diet were form ... | 2002 | 12534834 |
| the ability of betaine to reduce the irritating effects of detergents assessed visually, histologically and by bioengineering methods. | a novel approach for reducing the undesired irritating properties of detergents on skin might be offered by betaine, which is a natural product derived from the sugar beet. the aim of the study was to explore the ability of betaine to reduce the irritating effects of two surfactants, sodium lauryl sulphate (sls) and cocoamidopropylbetaine (capb). for evaluation of changes in skin reactions visual scoring, electrical impedance, transepidermal water loss and histology were used. | 2003 | 12535285 |
| expression of bacterial poly(3-hydroxybutyrate) synthesis genes in hairy roots of sugar beet (beta vulgaris l.). | three genes from ralstonia eutropha necessary for poly(3-hydroxybutyrate) (phb) synthesis were introduced into the hairy roots of sugar beet. transformation of a vector construct harbouring the phb genes, each fused to the coding region of the pea ribulose-bisphosphate carboxylase plastid targeting sequence, resulted in 20 transgenic hairy-root clones, producing up to 55 mg high molecular phb/g dry weight, as identified by gas chromatography, gel permeation chromatography and hplc. accumulation ... | 2003 | 12536258 |
| effects of dietary protein and fermentable fiber on nitrogen excretion patterns and plasma urea in grower pigs. | effects of dietary protein concentration (high, 18.5; low, 15.7%) and fermentable fiber (control; soyhulls, sh; and sugar beet pulp, sbp) on n excretion patterns and plasma urea were tested in a 2 x 3 factorial arrangement. the objectives were: 1) to determine if reduced dietary protein together with fermentable fiber would reduce urinary n excretion further than a single diet manipulation, 2) to determine if effects of diet manipulations were similar between pigs with restricted and free access ... | 2002 | 12542166 |
| chemoprevention of dmba-induced uv-b promoted, nor-1-induced tpa promoted skin carcinogenesis, and den-induced phenobarbital promoted liver tumors in mice by extract of beetroot. | our previous studies identified the extract of beta vulgaris (beetroot), commercially also known as betanin, as a potent cancer chemopreventive agent in both in vitro epstein-barr early antigen activation assay and in an in vivo two-stage mouse lung and skin carcinogenesis. to explore this issue further, we have now investigated its cancer chemopreventive potentials in three different chemical carcinogen initiation-promotion experimental tumor models in mice. following tumor initiation with 390 ... | 2003 | 12543062 |
| regulation of the fast vacuolar channel by cytosolic and vacuolar potassium. | at resting cytosolic ca(2)(+), passive k(+) conductance of a higher plant tonoplast is likely dominated by fast vacuolar (fv) channels. this patch-clamp study describes k(+)-sensing behavior of fv channels in beta vulgaris taproot vacuoles. variation of k(+) between 10 and 400 mm had little effect on the fv channel conductance, but a pronounced one on the open probability. shift of the voltage dependence by cytosolic k(+) could be explained by screening of the negative surface charge with a dens ... | 2003 | 12547779 |
| the 64-kilodalton capsid protein homolog of beet yellows virus is required for assembly of virion tails. | the filamentous virion of the closterovirus beet yellows virus (byv) consists of a long body formed by the major capsid protein (cp) and a short tail composed of the minor capsid protein (cpm) and the virus-encoded hsp70 homolog. by using nano-liquid chromatography-tandem mass spectrometry and biochemical analyses, we show here that the byv 64-kda protein (p64) is the fourth integral component of byv virions. the n-terminal domain of p64 is exposed at the virion surface and is accessible to anti ... | 0 | 12551975 |
| potassium-selective channel in the red beet vacuolar membrane. | in higher plants the vacuolar k(+)-selective (vk) channel was identified solely in guard cells. this patch-clamp study describes a 40 ps homologue of the vk channel in beta vulgaris taproot vacuoles. this voltage-independent channel is activated by submicromolar ca(2+), and is ideally selective for k(+) over cl(-) and na(+). | 2003 | 12554709 |
| feed intake of young double-muscled bulls fed on grass and supplemented with sugar-beet pulp. | daily dry matter intake in young growing double-muscled bulls, fed indoors on grass, was estimated based on forty-four intake data from 28 animals, ageing at least five months and weighing up to 400 kg live weight. intake was measured during five consecutive days using one of eighteen cuts of grass. fresh meadow grass (mainly lolium perenne) was fed ad libitum and two kg dried sugar-beet pulp was offered per animal and per day. animal live weight averaged 278 +/- 82 kg and mean total daily dry m ... | 2002 | 12556046 |
| effect of diet and gnrh administration on post-partum ovarian cyclicity in autumn-lambing ewes. | using autumn-lambing ewes, this study investigated (i) the effects of diet on gonadotrophin secretion and responsiveness of the hypothalamic-pituitary-ovarian axis to exogenous gnrh during the early post-partum period; and (ii) whether ovulation prior to completion of uterine involution results in an increased incidence of aberrant ovarian cycles. thirty-two ewes rearing 1.9+/-0.12 lambs were equally allocated to two dietary treatments at lambing (22 october +/-0.2 day). diets comprised ad libit ... | 2003 | 12559721 |
| quantitative determination of geosmin in red beets (beta vulgaris l.) using headspace solid-phase microextraction. | an improved analytical method for the determination of geosmin in red beets was developed using headspace solid-phase microextraction (hspme). volatiles of beet juice were extracted in headspace for 2 h using a polydimethylsiloxane/divinylbenzene fiber, thermally desorbed from the fiber, and analyzed by gas chromatography. the hspme method was determined to be suitable for geosmin analysis as evidenced by high relative recovery (99.2%), low relative standard deviation (7.48%), and reasonable det ... | 2003 | 12568566 |
| biosynthetic origin of geosmin in red beets (beta vulgaris l.). | geosmin provides the characteristic but sometimes undesirable "earthy" flavor to red table beets. to date, it is not known whether geosmin is a byproduct of beet metabolism or synthesized by soil-borne microorganisms and taken up by the beets during maturation. analysis of mature beet roots revealed that peels contained 6 times the amount of geosmin compared to the bodies and cores. sterilized beet seeds were aseptically grown in a basal medium prior to analysis for the presence of geosmin. usin ... | 2003 | 12568567 |
| quantitative relationships between induced jasmonic acid levels and volatile emission in zea mays during spodoptera exigua herbivory. | jasmonic acid (ja) has long been hypothesized to be an important regulator of insect-induced volatile emission; however, current models are based primarily on circumstantial evidence derived from pharmacological studies. using beet armyworm caterpillars (baw: spodoptera exigua) and intact corn seedlings, we examine this hypothesis by measuring both the time-course of insect-induced ja levels and the relationships between endogenous ja levels, ethylene, indole and sesquiterpenes. in separate morn ... | 2003 | 12569409 |
| production of cyclic lipopeptides by pseudomonas fluorescens strains in bulk soil and in the sugar beet rhizosphere. | the production of cyclic lipopeptides (clps) with antifungal and biosurfactant properties by pseudomonas fluorescens strains was investigated in bulk soil and in the sugar beet rhizosphere. purified clps (viscosinamide, tensin, and amphisin) were first shown to remain highly stable and extractable (90%) when applied (ca. 5 microg g(-1)) to sterile soil, whereas all three compounds were degraded over 1 to 3 weeks in nonsterile soil. when a whole-cell inoculum of p. fluorescens strain dr54 contain ... | 2003 | 12571005 |
| surface motility in pseudomonas sp. dss73 is required for efficient biological containment of the root-pathogenic microfungi rhizoctonia solani and pythium ultimum. | pseudomonas sp. dss73 was isolated from the rhizoplane of sugar beet seedlings. this strain exhibits antagonism towards the root-pathogenic microfungi pythium ultimum and rhizoctonia solani. production of the cyclic lipopeptide amphisin in combination with expression of flagella enables the growing bacterial culture to move readily over the surface of laboratory media. amphisin is a new member of a group of dual-functioning compounds such as tensin, viscosin and viscosinamid that display both bi ... | 2003 | 12576578 |

| using seed purity data to estimate an average pollen mediated gene flow from crops to wild relatives. | gene flow from crops to wild related species has been recently under focus in risk-assessment studies of the ecological consequences of growing transgenic crops. however, experimental studies addressing this question are usually temporally or spatially limited. indirect population-structure approaches can provide more global estimates of gene flow, but their assumptions appear inappropriate in an agricultural context. in an attempt to help the committees providing advice on the release of transg ... | 2002 | 12579439 |
| high-resolution mapping of the bolting gene b of sugar beet. | sugar beet ( beta vulgaris l.) is a biennial species. shoot elongation (bolting) starts after a period of low temperature. the dominant allele of locus b causes early bolting without cold treatment. this allele is abundant in wild beets whereas cultivated beets carry the recessive allele. fifteen aflp markers, tightly linked to the bolting locus, have been identified using bulked segregant analysis. the f(2)-population consisted of 2,134 individuals derived after selfing a single f(1)-plant ( bb ... | 2002 | 12582567 |
| mapping qtls for sucrose content, yield and quality in a sugar beet population fingerprinted by est-related markers. | seventy five expressed sequence tags (ests) that are associated with functions in carbohydrate and nitrogen metabolism were genotyped in 108 plants of an f2 population of sugar beet ( beta vulgaris l.) segregating for sugar quality and yield parameters. supplemented by known rflp and aflp markers, the resulting map spans 446 cm of the 758-mbp genome of sugar beet. f3 test-cross plants were analysed for corrected sugar yield, beet yield, ion balance and the content of sugar, amino nitrogen, potas ... | 2002 | 12582619 |
| crop-weed interactions in the beta vulgaris complex at a local scale: allelic diversity and gene flow within sugar beet fields. | crop-wild hybrids and weed beets are the main source of agronomic concern for sugar beet production all over europe. in order to understand the dynamics of crop-wild interactions and the evolution of weediness in beta vulgaris, we investigated genetic features of bolting individuals occurring at a local scale, i.e. within two sugar beet fields of the french northern area of sugar beet production. by analysing ploidy level, mitochondrial dna and microsatellite polymorphism, the genetic diversity ... | 2002 | 12582675 |
| the sugar beet mitochondrial nad4 gene: an intron loss and its phylogenetic implication in the caryophyllales. | the sugar beet mitochondrial gene for subunit iv of nadh dehydrogenase ( nad4) has been characterized. unlike the corresponding genes in wheat and turnip, sugar beet nad4 lacks the second intron ( nad4-i2). northern-blot analysis demonstrates transcription of the gene. a total of 19 rna editing sites were identified in the sugar beet nad4 transcripts; interestingly, there is no editing in the region which flanks the lost intron. this observation is in favour of intron loss via homologous recombi ... | 2002 | 12582688 |
| leader proteinase of beet yellows virus functions in long-distance transport. | the 66-kda leader proteinase (l-pro) of the beet yellows virus (byv) possesses a nonconserved n-terminal domain and a conserved, papain-like c-terminal domain. previous work revealed that the n-terminal domain functions in rna amplification, whereas the c-terminal domain is required for autoproteolysis. alanine-scanning mutagenesis was applied to complete the functional analysis of l-pro throughout the virus life cycle. this analysis indicated that the c-terminal domain of l-pro, in addition to ... | 2003 | 12584307 |
| multitasking in replication is common among geminiviruses. | geminiviruses package single-stranded circular dna and replicate via double-stranded dna intermediates. during the past decade, increasing evidence has led to the general acceptance that their replication follows a rolling-circle replication mechanism like bacteriophages with single-stranded dna. in a recent study, we showed that this is also true for abutilon mosaic geminivirus (abmv), but that this particular virus may also use a recombination-dependent replication (rdr) route in analogy to t4 ... | 2003 | 12584322 |
| effects of point mutations in the major capsid protein of beet western yellows virus on capsid formation, virus accumulation, and aphid transmission. | point mutations were introduced into the major capsid protein (p3) of cloned infectious cdna of the polerovirus beet western yellows virus (bwyv) by manipulation of cloned infectious cdna. seven mutations targeted sites on the s domain predicted to lie on the capsid surface. an eighth mutation eliminated two arginine residues in the r domain, which is thought to extend into the capsid interior. the effects of the mutations on virus capsid formation, virus accumulation in protoplasts and plants, ... | 2003 | 12584348 |
| identification and exploitation of novel disease resistance genes in sugar beet. | sugar beet is a valuable arable crop providing a large proportion of world sugar supplies. it is susceptible to a range of fungal and viral diseases, to most of which there is inadequate genetic resistance. control instead relies largely on the use of pesticides. to increase the sustainability of sugar-beet cultivation, strong and durable genetic resistance is urgently needed. this review describes an iacr-broom's barn programme devoted to evaluating beta germplasm for novel resistance to major ... | 2003 | 12587876 |
| variability of cathodic peroxidases in sugar beet (beta vulgaris l.) cultivars. | eighteen varieties of sugar beet (beta vulgaris l.), originating from various european countries, were compared in respect of peroxidase variability level. they were cultivated in the same experimental plot. the cultivars differed in ploidy level: one variety was tetraploid, three were diploid and 14 varieties were triploid. the cathodic peroxidase system is controlled by four independent genes, of which only one is polymorphic. consequently, the varieties were characterised by frequencies of 3 ... | 2003 | 12590181 |
| effects of dietary fermentable carbohydrates on behavior and heat production in group-housed sows. | the effects of dietary nonstarch polysaccharides (nsp) on behavior and heat production in group-housed sows were studied. twelve groups of six nonpregnant sows were fed one of four experimental diets that were similar in composition except for starch and nsp contents. exchanging sugar beet pulp silage (sbps) for tapioca created the difference in dietary starch and nsp ratio. on a dry matter (dm) basis, diets contained 0, 10, 20, or 30% sbps. sows were group-housed. intake of fermentable nsp (fns ... | 2003 | 12597389 |
