Postharvest management of gray mold and brown rot on surfaces of peaches and grapes using electrolyzed oxidizing water.

This study evaluated the potential use of near-neutral (pH=6.3-6.5) electrolyzed oxidizing water (EO water) to inactivate pure cultures of Botrytis cinerea and Monilinia fructicola and to mitigate fungal infection of these organisms on fruit surfaces.

Reduction of bacteria on spinach, lettuce, and surfaces in food service areas using neutral electrolyzed oxidizing water.

Food safety issues and increases in food borne illnesses have promulgated the development of new sanitation methods to eliminate pathogenic organisms on foods and surfaces in food service areas. Electrolyzed oxidizing water (EO water) shows promise as an environmentally friendly broad spectrum microbial decontamination agent. EO water is generated by the passage of a dilute salt solution ( approximately 1% NaCl) through an electrochemical cell.

Four isoforms of glutamine synthetase in light-grown soybeans.

Glutamine synthetase (GS) activity recovered from linear sucrose gradients was associated with the cytosol of cells isolated from etiolated soybean hypocotyls whereas light-grown tissue contained increased GS activity localized in both the cytosol and chloroplasts. DEAE-cellulose chromatography indicated two GS isoforms in etiolated hypocotyls whereas light-grown hypocotyls and primary leaves contained four isoforms. Only one GS isoform was recovered from both etiolated and light-grown cotyledons.

Separation and partial characterization of multiple ribonucleic Acid polymerases from soybean hypocotyl.

Two major peaks of RNA polymerase activity have been routinely separated by diethylaminoethyl cellulose chromatography following solubilization from soybean (Glycine max L. var. Wayne) chromatin.

Effects of gamma irradiation on chromatin activity of sugar beet tissue.

Chromatin-associated RNA polymerase activity increases during washing of sugar beet tissue to a maximum by 20 hours. This increase was inhibited by dosages of gamma irradiation between 50 and 400 krad. Template availability, as measured by saturating levels of added Escherichia coli RNA polymerase, also increased with washing and was inhibited, although to a lesser extent, by the above irradiation dosages.

Synergistic effects of metabolically related amino acids on the growth of a multicellular plant. II. Studies of 14C-amino acid incorporation.

The synergistic inhibition of the growth of Marchantia polymorpha gemmalings by lysine and threonine and its prevention by methionine has been investigated utilizing (14)C-labeled amino acids. Experiments involving the uptake of (14)C-lysine or (14)C-threonine in the presence or absence of methionine indicated that the synergistic growth effects were not a result of altered amino acid uptake. These data, as well as direct chemical analysis, indicated that growth inhibition was correlated with an inhibition of protein synthesis.

Synergistic effects of metabolically related amino acids on the growth of a multicellular plant.

The effects of several amino acids related to the metabolism of aspartic acid on the growth and development of gemmalings of the liverwort Marchantia polymorpha were investigated under axenic conditions. Lysine and theonine synergistically inhibit the growth of these plants and cause a loss of normal pigmentation at concentrations as low as 1 mum. These effects are highly specific for this pair of amino acids, are partially reversible upon removal of the effectors, and can be prevented by low concentrations of methionine or its metabolic precursor, homoserine.
