| kinetics of hydration and functional specific gravity of fibrous feed by-products. | five studies were conducted to evaluate the kinetics of digestion, hydration, and functional specific gravity (fsg) of various feed by-products (fbp) in vitro. the water-holding capacity (whc) of alfalfa and orchardgrass (1.428 and 1.005 g/g of insoluble dm [idm], respectively) was higher (p < .05) than the whc of fbp, which ranged from .175 for distillers grains to .481 g/g of idm for brewers grains pellets. rate of hydration was the highest in brewers grains pellets and beet pulp (.215 and .25 ... | 1995 | 7665376 |
| early iron deficiency stress response in leaves of sugar beet. | iron nutrient deficiency was investigated in leaves of hydroponically grown sugar beets (beta vulgaris) to determine how ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) gene expression is affected when thylakoid components of photosynthesis are diminished. rubisco polypeptide content was reduced by 60% in severely iron-stressed leaves, and the reduction was directly correlated to chlorophyll content. the concentration of rubisco protein in iron-stressed leaves was found to be regulated ... | 1995 | 7659749 |
| characterization and localization of new antifungal cysteine-rich proteins from beta vulgaris. | two novel antifungal proteins, ax1 and ax2, were isolated from leaves of sugar beet infected with cercospora beticola. ax1 (mw = 5078 +/- 3d) and ax2 (mw = 5193 +/- 3d) were n-terminally sequenced and identified as monomeric, basic proteins consisting of 46 amino acid residues, of which eight are cysteines. both ax proteins strongly inhibit growth of c. beticola and other filamentous fungi, but have little or no effect against bacteria. based on primary sequence homology (24 to 46% identity), th ... | 1995 | 7655063 |

| atp, ph and mg2+ modulate a cation current in beta vulgaris vacuoles: a possible shunt conductance for the vacuolar h(+)-atpase. | macroscopic instantaneous and time-dependent currents have been measured in the vacuolar membrane of beta vulgaris using a patch clamp configuration analogous to whole cell mode. at low cytosolic ca2+ and in the absence of mg2+, only an instantaneous current was observed. this current is carried predominantly by cations (pk:pcl 7:1, pna:pcl 4:1 and arginine is also conducted). the instantaneous current can be activated by atp4- (e.g., atp-activated mean k+ current density was -20 ma.m-2 at a mem ... | 1995 | 7636887 |
| detection of beet necrotic yellow vein virus strains, variants and mixed infections by examining single-strand conformation polymorphisms of immunocapture rt-pcr products. | single-strand conformation polymorphism analysis was found to be a powerful tool for rapidly assigning large numbers of beet necrotic yellow vein virus (bnyvv) isolates to a known strain group as well as for detecting mixed infections, minor variants or new strain groups. the prevalence of the b-type in germany and france and the a-type in most other countries was confirmed. minor variants with a very restricted distribution were detected occasionally. new rhizomania outbreaks in great britain w ... | 1995 | 7636486 |
| the consequences of fruit and vegetable fibre fermentation on their binding capacity for meiqx and the effects of soluble fibre sources on the binding affinity of wheat bran preparations. | fruits and vegetables provide dietary fibre some of which is partly soluble in the upper gut; in the colon it is highly fermentable. using alcohol-insoluble residues prepared from a range of fruits and vegetables the effects of fermentation on the changes in composition and binding capacity have been assessed for the hydrophobic mutagen 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (meiqx). fermentation was extensive and resulted in destruction of most of the pectic polysaccharides. of the unfer ... | 1995 | 7634394 |

| dietary fiber for dogs: iv. in vitro fermentation of selected fiber sources by dog fecal inoculum and in vivo digestion and metabolism of fiber-supplemented diets. | two experiments were conducted to evaluate single sources and blends of dietary fiber in dog food. in exp. 1, 14 fibrous substrates were fermented in vitro using dog feces as the source of inoculum. organic matter disappearance was lowest (p < .05; < 10%) for solka floc and oat fiber and greatest (p < .05; > 80%) for fructooligosaccharides (fos) and lactulose. solka floc, oat fiber, gum karaya, and xanthan gum produced the least (p < .05; < 1 mmol/g of substrate om) total short-chain fatty acids ... | 1995 | 7628954 |
| chronic and postprandial responses of plasma insulin, glucose and lipids in volunteers given dietary fibre supplements. | we questioned whether a dietary fibre supplement known to lower fasting plasma cholesterol concentrations can also lower the postprandial plasma cholesterol, glucose and insulin concentrations when it is administered just before a meal. two studies were conducted in healthy middle-aged volunteers of both sexes in whom the fasting plasma total cholesterol concentrations were above normal. in the first study the dietary fibre treatments (2.2 g) were psyllium and a psyllium-citrus pectin mixture to ... | 1995 | 7626592 |

| the plant vacuolar na+/h+ antiport. | salt stress imposes severe limitations on plant growth, however, the extent of growth reduction depends upon the soil salinity level and the plant species. one of the mechanisms employed by salt tolerant plants is the effective vacuolar compartmentalization of sodium. the sequestration of sodium into the vacuole occurs by the operation of a na+/h+ antiport located at the tonoplast. evidence for a plant vacuolar na+/h+ antiport has been demonstrated in tissues, intact vacuoles and isolated tonopl ... | 1994 | 7597639 |
| voltage-gated ca2+ release channels in vacuolar membranes from beet storage roots and guard cells. | the ubiquity and wide-ranging roles of ca(2+)-mediated stimulus-response coupling in plant cells is likely to demand flexibility in the duration and amplitude of the cytosolic ca2+ signal. the presence of both ligand- and voltage-gated ca2+ release channels at the vacuolar membrane suggests that this flexibility might be achieved through differential regulation of these discrete channel classes. the properties and distribution of voltage-gated vacuolar ca2+ channels is described in this chapter. ... | 1994 | 7597637 |
| pcr and non-isotopic labeling techniques for plant virus detection. | pcr technology permits the detection of viruses at levels several orders of magnitude lower than is possible by other methods. this high sensitivity facilitates detection of virus sequences during the early stages of infection of plants and in soil and vector samples. early detection of beet necrotic yellow vein virus (bnyvv) in beta vulgaris is an important part of the strategy for prevention of the spread of rhizomania, a commercially significant disease of sugar beet. a diagnostic test for bn ... | 1995 | 7580844 |
