1. The influx of potassium ions in leaves of Elodea densa during short periods of time was measured using (42)K and (86)Rb as tracers. The K(+) influx was linear with time (Fig. 1) without a contribution by Donnan adsorption even in 1 min experiments. 2. Light increased the K(+) influx in air by a
The invasive aquatic plant Elodea nuttallii was subjected to hydrothermal carbonization at 200 °C and 240 °C to produce biochar. About 58% w/w of the organic carbon of the pristine plant was translocated into the solid biochar irrespectively of the operating temperature. The process water rich in
Native gellan, the natural form of the polysaccharide excreted by the bacterium Pseudomonas elodea, has a tetrasaccharide repeating unit that contains L-glycerol and acetate ester groups, and forms only weak and elastic gels. Based on X-ray diffraction data from well oriented and polycrystalline
It has been a dogma since the success of chemiosmotic theory that plants use protons as a membrane-coupling mechanism--it has come to be implied that they use no other ion for the purpose. Following the finding that potassium can be taken up by sodium symport in Chara australis, we have established
The addition of potassium bicarbonate to the electrode cuvette immediately stimulated the rate of dark O(2) uptake of photomixotrophic and heterotrophic carnation (Dianthus caryophyllus L.) callus, of Elodea canadensis (Michx) leaves, and of other plant tissues. This phenomenon occurred at pH values
