Nucleic Acids of Chloroplasts and Mitochondria in Swiss Chard
Nucleic acids in young leaves of Swiss chard have been studied by light and electron microscope techniques. Leaf DNA has also been characterized by density gradient centrifugation and shown to contain a minor band of higher guanine plus cytosine (GC) content, presumably attributable to chloroplasts. The chloroplasts were faintly stained by the Feulgen reaction; radioautography demonstrated the ...
متن کاملNarK enhances nitrate uptake and nitrite excretion in Escherichia coli.
narK mutants of Escherichia coli produce wild-type levels of nitrate reductase but, unlike the wild-type strain, do not accumulate nitrite when grown anaerobically on a glucose-nitrate medium. Comparison of the rates of nitrate and nitrite metabolism in cultures growing anaerobically on glucose-nitrate medium revealed that a narK mutant reduced nitrate at a rate only slightly slower than that i...
متن کاملAvron M. Photophosphorylation by Swiss Chard chloroplasts. Biochim. Biophys. Acta 40: 257-72, 1960
The article describes a detailed study for optimizing the conditions for preparation of chloroplasts from leaves of higher plants and of the reaction conditions for measuring photophosphorylation. Under the conditions specified, the world record rate.(which still holds) of light-induced ATP formation, approaching 2500 μ moles X mg chl-1 X hr-1, was attained. A simple assay system for following ...
متن کاملBrain serotonin depletion enhances the sodium appetite induced by sodium depletion or beta-adrenergic stimulation.
We investigate the influence of brain serotonin depletion on the sodium appetite. Rats depleted of serotonin through the systemic administration of p-chlorophenylalanine (300 mg/kg, ip, for 2 days) showed an intense natriorexigenic response induced by sodium depletion (furosemide, 20 mg/kg, sc, 24 h before water and 1.8% NaCl presentation). Intake of 1.8% NaCl was always higher than that observ...
متن کاملKinetics of Sphalerite Leaching by Sodium Nitrate in Sulfuric Acid
In the present work, the extraction of zinc from a sphalerite concentrate using sodium nitrate as an oxidant in a sulfuric acid solution was investigated. The effective parameters such as the temperature, sulfuric acid and sodium nitrite concentrations, stirring speed, particle size, and solid/liquid (S/L) ratio were analyzed. The dissolution rate increased with increase in the sulfuric acid an...
