| comparative enzymic studies of sucrose metabolism in the taproots and fibrous roots of beta vulgaris l. | comparative enzymic studies of sugar beet (beta vulgaris l.) taproots and fibrous roots revealed differences in invertase (ec 3.2.1.26) and sucrose synthetase (ec 2.4.1.13) activity. invertase activity of the two root forms differs with respect to specific activity, ph optimum, and enzyme solubility. acid invertase (ph 4.5) in the taproot was restricted to the peripheral meristematic tissue which produces cells for both taproot and fibrous root growth. this finding supports the hypothesis that t ... | 1979 | 16661094 |
| erratum. | a news and comment briefing, "carcinogens in scotch" (24 aug., p. 769), incorrectly reported that carrot and beet juice contain relatively high levels of nitrosamines. so far as is known, they do not. they do contain nitrates and nitrites, the precursors of nitrosamines. | 1979 | 17796916 |
| sucrose uptake by sugar beet tap root tissue. | sucrose uptake by discs of mature sugar beet root tissue incubated in [(14)c]-sucrose exhibited nonsaturating kinetics over the concentration range of 1 to 500 millimolar. uptake was inhibited by dinitrophenol, sodium cyanide, low o(2), and penetrating sulfhydryl inhibitors. atpase inhibitors, sodium fluoride, and oligomycin reduced uptake by 20 and 40%, respectively. uptake as asymmetrically labeled sucrose ([(14)c]glucose) occurred with approximately 80% retention of asymmetry, indicating a no ... | 1979 | 16661065 |
| effect of exogenously supplied foliar potassium on phloem loading in beta vulgaris l. | the effect of foliar application of k(+) on processes associated with phloem loading was investigated in source leaves of sugar beet (beta vulgaris l.). kci was supplied exogenously at concentrations of up to 100 millimolar in the solution bathing the abraded upper epidermis of source leaves. k(+) added at concentrations below 30 millimolar generally promoted the rate of export of material derived from (14)co(2) but not from exogenously applied [(14)c]sucrose. paralleling promotion of export, th ... | 1979 | 16661003 |
| sucrose translocation and storage in the sugar beet. | several physiological processes were studied during sugar beet root development to determine the cellular events that are temporally correlated with sucrose storage. the prestorage stage was characterized by a marked increase in root fresh weight and a low sucrose to glucose ratio. carbon derived from (14)c-sucrose accumulation was partitioned into protein and structural carbohydrate fractions and their amino acid, organic acid, and hexose precursors. the immature root contained high soluble aci ... | 1979 | 16660821 |
| phloem loading of sucrose: involvement of membrane atpase and proton transport. | p-chloromercuribenzenesulfonic acid markedly inhibited sucrose accumulation into sugar beet source leaves without inhibiting hexose accumulation. the site of inhibition is proposed to be the plasmalemma atpase, since the atpase-mediated h(+) efflux was completely inhibited by p-chloromercuribenzenesulfonic acid under conditions where intracellular metabolism, as measured by photosynthesis and hexose accumulation, was unaffected. fusicoccin, a potent activator of active h(+)/k(+) exchange, stimul ... | 1979 | 16660804 |
| the location of acid invertase activity and sucrose in the vacuoles of storage roots of beetroot (beta vulgaris). | vacuoles were isolated from freshly cut slices of the storage roots of beetroot (beta vulgaris), and from slices that had been washed in aerated water for 1-3 days. the unique vacuolar location of betanin permitted the use of a correlative method to determine whether sucrose and acid invertase were located in the vacuoles. the specific content (the activity of the enzyme or amount of substrate per mg of protein) and the percentage recoveries for betanin, sucrose and acid invertase were determine ... | 1979 | 454363 |
| a study of formate production and oxidation in leaf peroxisomes during photorespiration. | when glycolate was metabolized in peroxisomes isolated from leaves of spinach beet (beta vulgaris l., var. vulgaris) formate was produced. although the reaction mixture contained glutamate to facilitate conversion of glycolate to glycine, the rate at which h(2)o(2) became "available" during the oxidation of [1-(14)c]glycolate was sufficient to account for the breakdown of the intermediate [1-(14)c]glyoxylate to formate (c(1) unit) and (14)co(2). under aerobic conditions formate production closel ... | 1979 | 16660715 |
| accumulation of sucrose in vacuoles isolated from red beet tissue. | vacuoles were isolated from red beets (beta vulgaris l.) by slicing the tissue and separated using a discontinuous dextran gradient centrifugation. the uptake of sucrose against a concentration gradient into the dextran-impermeable [(3)h]-h2o space of these organelles was studied using silicone layer filtering centrifugation on both fluorometric and (14)c-measurement of sucrose. the rate is 24 nmol sucrose (unit betacyanin)(-1) h(-1) and appears to be stimulated by atp to an uptake rate of 34 nm ... | 1979 | 24407383 |
| superiority of a soil debris isolation method over a beet seed colonization method for assay of rhizoctonia solani at high soil inoculum densities. | a quantitative soil debris isolation method (all debris from known weight of soil plated) and a garden beet seed saprophytic colonization method were compared over a 1-year period for assaying rhizoctonia solani population. four fields of different soil textures were selected. within each field four areas of healthy and four areas of diseases (rhizoctonia root and crown rot) sugarbeets were sampled bimonthly from august 1976 until june 1977. the maximum numbers of r. solani colonies obtained by ... | 1979 | 427651 |
| two forms of α-glucosidase from sugar-beet seeds. | two forms of α-glucosidase (ec 3.2.1.20), designated as i and ii, have been isolated from sugarbeet (beta vulgaris l.) seeds by a procedure including fractionation with ammonium sulfate and ethanol, carboxymethyl-cellulose column chromatography, and preparative disc gel electrophoresis. the two enzymes were homogeneous by polyacrylamide disc gel electrophoresis. their molecular weights were 98,000 (i) and 60,000 (ii). α-glucosidase i readily hydrolyzed maltose, isomaltose, kojibiose, maltotriose ... | 1980 | 24310138 |
| limiting factors in photosynthesis: ii. iron stress diminishes photochemical capacity by reducing the number of photosynthetic units. | it has been proposed that fe stress may be used in the study of limiting factors in photosynthesis as an experimental means of varying photochemical capacity in vivo (plant physiol 1980 65: 114-120). in this paper the effect of fe stress on photosynthetic unit number, size, and composition was investigated by measuring p(700), cytochrome (cyt) f, chlorophyll (chl) a, and chl b in sugar beet leaves. the results show that when fe stress reduced chl per unit area by 80% (from 60 to 12 micrograms pe ... | 1980 | 16661124 |
| limiting factors in photosynthesis: i. use of iron stress to control photochemical capacity in vivo. | the possibility of using fe stress as an experimental tool in the study of limiting factors was explored. results show that fe stress decreased the chlorophyll (chl) a, chl b, carotene, and xanthophyll content of leaves of sugar beets (beta vulgaris l.) and that the maximum rate of photosynthetic co(2) uptake (p(max)) per unit area was linearly related to chl (a + b) per unit area. measurements of noncyclic atp formation by isolated chloroplasts at light saturation indicate that photosynthetic e ... | 1980 | 16661123 |
| [nitrite and nitrate content of foods sampled during national food quality monitoring]. | the aim of the french national inquiry of food quality is to ascertain the presence in food of many contaminants, in particular nitrates and nitrites. because of variability of contamination in samples, a great number of determinations were carried out for each food kind (2296 determinations in 62 foods kinds). nitrate amounts are in fact very high in beet roots, white beets, celery salads, radishes and green salads. | 1980 | 7258921 |

| atpase and acid phosphatase activities associated with vacuoles isolated from storage roots of red beet (beta vulgaris l.). | phosphatase activities were measured in preparations of vacuoles isolated from storage roots of red beet (beta vulgaris l.). the vacuoles possessed both acid phosphatase and atpase activities which could be distinguished by their susceptibility to inhibition by low concentrations of ammonium molybdate [(nh4)6mo7o24·4h2o]. the acid phosphatase was completely inhibited by 100 μm ammonium molybdate but the atpase was unaffected. the acid phosphatase was a soluble enzyme which hydrolysed a large num ... | 1980 | 24306686 |
| effect of rapid changes in sink-source ratio on export and distribution of products of photosynthesis in leaves of beta vulgaris l. and phaseolus vulgaris l. | effects of increasing sink-source ratio on rate of translocation and net carbon exchange were studied by darkening all but one source leaf of beta vulgaris l. or one primary leaf of phaseolus vulgaris l. rates of export of labeled material and patterns of its distribution among sinks were studied by means of gm detectors. changes in export and import rates were compared with adjustments in starch, sucrose, and glucose levels in sugar beet source leaves before and during treatment.sugar beet sour ... | 1980 | 16661558 |
| alkali cation/sucrose co-transport in the root sink of sugar beet. | the mechanism of sucrose transport into the vacuole of root parenchyma cells of sugar beet was investigated using discs of intact tissue. active sucrose uptake was evident only at the tonoplast. sucrose caused a transient 8.3 millivolts depolarization of the membrane potential, suggesting an ion co-transport mechanism. sucrose also stimulated net proton efflux. active (net) uptake of sucrose was strongly affected by factors that influence the alkali cation and proton gradients across biological ... | 1980 | 16661546 |
| effects of ph and ethephon on betacyanin leakage from beet root discs. | betacyanin leakage from beet root discs was found to increase with decreasing ph of the incubation medium. although 10 millimolar ca(2+) reduced pigment leakage at ph 3.5, it was ineffective at ph 2.3. leakage was also stimulated by 100 micrograms per milliliter (2-chloroethyl)-phosphonic acid (ph 3.1), but when the solution was neutralized, this leakage was eliminated. bubbling c(2)h(4) through a neutral medium containing beet discs had no effect on pigment leakage; it appears that the effect o ... | 1980 | 16661525 |

| localization of filipin-sterol complexes in the membranes of beta vulgaris roots and spinacia oleracea chloroplasts. | filipin was used as a cytochemical probe for membrane sterols in the root storage tissue of the red beet beta vulgaris l. and the chloroplasts of spinacia oleracea l. in unfixed beet tissue, filipin lysed the cells. freeze-fracture replicas revealed that the filipin-sterol complexes were tightly aggregated in the plasma membrane, while in thin section the complexes corrugated the plasma membrane. if the cells were fixed with glutaraldehyde prior to the filipin treatment, the cell structure was p ... | 1982 | 16662716 |
| limiting factors in photosynthesis: iii. effects of iron nutrition on the activities of three regulatory enzymes of photosynthetic carbon metabolism. | when fe was withheld from sugar beets (beta vulgaris l. cv f58-44h1), the activities of nadp-glyceraldehyde-3-phosphate dehydrogenase, fructose 1,6-bisphosphatase, and ribulose 5-phosphate kinase were not diminished, while chlorophyll per area was decreased by 75%. on resupplying fe, chlorophyll per area increased to control levels within 5 days, whereas the activities of the three enzymes remained approximately constant. these results support the view advanced earlier (terry 1980 plant physiol ... | 1982 | 16662713 |
| sucrose and glucose uptake into beta vulgaris leaf tissues : a case for general (apoplastic) retrieval systems. | concentration curves for sugar and amino acid uptake by beta vulgaris l. leaf tissues contained both a saturable and a linear component. similarly shaped curves were obtained for influx of sucrose, glucose, and 3-o-methyl glucose by leaf discs, whole petiole slices, petiole segments containing pith tissue only, and petiole segments containing vascular bundles, although the tissues took up the various sugars via different proportions of saturable versus linear uptake. two millimolar p-chloromercu ... | 1982 | 16662694 |
| biosynthesis, translocation, and accumulation of betaine in sugar beet and its progenitors in relation to salinity. | like other halophytic chenopods, sugar beet (beta vulgaris l.) can accumulate high betaine levels in shoots and roots. n,n,n-trimethylglycine impedes sucrose crystallization and so lowers beet quality. the objective of this research was to examine the genetic variability and physiological significance of betaine accumulation in sugar beet and its relatives. three cultivated genotypes of b. vulgaris and two genotypes of the wild progenitor b. maritima l. were grown with and without gradual salini ... | 1982 | 16662637 |
| salt tolerance in crop plants monitored by chlorophyll fluorescence in vivo. | the potential of measurements of chlorophyll fluorescence in vivo to detect cellular responses to salinity and degrees of salt stress in leaves was investigated for three crop plants. sugar beet (beta vulgaris l.) (salt tolerant), sunflower (helianthus annuus l.) (moderately salt tolerant), and bean (phaseolus vulgaris l. cv canadian wonder) (salt intolerant) were grown in pots and watered with mineral nutrient solution containing 100 millimolar nacl. the fast rise in variable chlorophyll fluore ... | 1982 | 16662611 |
| diurnal pattern of translocation and carbohydrate metabolism in source leaves of beta vulgaris l. | transitions in carbohydrate metabolism and translocation rate were studied for evidence of control of export by the sugar beet (beta vulgaris l. klein e.) source leaf. steady-state labeling was carried out for two consecutive 14-hour light periods and various quantities related to translocation were measured throughout two 24-hour periods. starch accumulation following illumination was delayed. near the end of the light period, starch stopped accumulating, whereas photosynthesis rate and sucrose ... | 1982 | 16662555 |
| nucleoside diphosphate levels in taproots and fibrous roots of beta vulgaris l. : implifications for control of sucrose allocation between two sinks. | sucrose synthase (ec 2.4.1.13) of sugarbeet (beta vulgaris l.) fibrous roots has a distinctly different order of preference for nucleoside diphosphate substrates than that of the taproot enzyme (silvius, snyder 1979 plant physiol 64: 1070-1073). separation and quantitation of udp, adp, and gdp in root extracts by high-pressure liquid chromatography revealed that udp levels in taproot tissue were 5 to 10 times greater than those of fibrous root tissues. the lower fibrous root udp levels were asso ... | 1982 | 16662470 |
| potassium nutrition and translocation in sugar beet. | the effect of increased net foliar k(+) accumulation on translocation of carbon was studied in sugar beet (beta vulgaris, l. var. klein e and us h20) plants. net accumulation of recently absorbed k(+) was studied by observing arrival of (42)k(+) per unit area of leaf. labeled k(+) was added to give an initial concentration at 2 or 10 millimolar k(+) in mineral nutrient solution. because the newly arrived k(+) constitutes a small part of the total leaf k(+) in plants raised in 10 millimolar k(+), ... | 1982 | 16662439 |
