    Notes: [Auszug] More recent experiments have shown that chloramphenicol interferes both with the uptake of amino-acids labelled with carbon-14 by slices of carrot root and with the incorporation of the label into newly synthesized soluble proteins of the tissue. It thus appears to be confirmed that chloramphenicol ...

    Notes: [Auszug] IT was observed by Steward and Millar1 that actively growing carrot and artichoke tissue cultures absorbed caesium ions more slowly per unit of fresh weight than did slowly growing cultures, and they concluded that, in general, the rate of uptake of salt is more rapid in vacuolated than in ...

    Notes: [Auszug] More recently, however, evidence has been accumulating that the ratio can exceed 4 in both animal and plant systems. Crane and Davies6 claimed that (hydrochloric acid secreted/oxygen involved) in frog gastric mueosae can be maintained at values exceeding 11 for considerable periods of time. Leaf ...

    Notes: [Auszug] A NUMBER of investigators have examined the effect of "H value of the medium on uptake of salts by plants1-4. In most cases little, if any, influence has been observed over a range of pH values from 5 to 9. A major difficulty in the interpretation of such experiments is that buffered solutions must ...

    Notes: [Auszug] IT has been shown1 that in water culture some plants may absorb both cations and anions at a rate which is independent over a wide range of the total concentration in the culture medium, provided their relative concentrations in the medium are kept fixed. Such results may be explained on the basis ...

    Notes: [Auszug] When investigating the distribution of p-glycerophos-phatase in the roots of Pisum sativum, we found a large increase in activity of this enzyme in the region of lateral root development. Enzyme assays were carried out on 1 mm serial sections of 5 day old roots. The sections were ground into ...

    Notes: [Auszug] SALT absorption in plants is clearly an energy-O requiring process; but the mechanism by which it is achieved remains obscure1. Experiments with metabolic inhibitors such as cyanide, azide, and carbon monoxide have confirmed the dependence on respiration, and indicate the involvement of the ...

    Characterization of galeal sugar and glucosinolate-sensitive cells inEntomoscelis americana adults (1982)
    Springer
    Journal of comparative physiology 146 (1982), S. 393-399 
    Details
    ISSN: 1432-1351
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary A restrained, whole animal preparation was used to study chemical sensitivity and specificity of three cells in the medial galeal chemosensillum of adult red turnip beetles. One cell is sensitive to sugars, particularly sucrose and maltose, two cells respond to glucosinolates and two to the glucoside arbutin. Responses to mixtures of these compounds revealed that arbutin stimulates the sugar-sensitive cell and one of the glucosinolate-sensitive cells. The second glucosinolate-sensitive cell was stimulated only by glucosinolates. Dose-response curves were determined for most of the compounds tested. The adult gustatory system differs in several respects from that of the larva. Sugar sensitivity is similar in both, though only in the larva is this cell also sensitive to amino acids. One of the glucosinolate-sensitive cells is similar in both stages, while the second cell is much more dose-dependent in adults. A fourth cell has been morphologically identified in both sensilla, but we were unable to determine its specificity.
