    Notes:
    Summary The 5′-upstream region of the class I patatin gene B33 directs strong expression of the β-glucuronidase (GUS) reporter gene in potato tubers and in leaves treated with sucrose. Cis-acting elements affecting specificity and level of expression were identified by deletion analysis in transgenic potato plants. A putative tuber-specific element is located downstream from position −195. Nuclear proteins present in leaf and tuber extracts bind specifically to a conserved AT rich motif within this region. A DNA fragment between −183 and −143, including the binding site is, however, not able to enhance the expression of a truncated 35S promoter from cauliflower mosaic virus. Independent positive elements contributing to a 100-fold increase relative to the basic tuber-specific element are located between −228 and −195; −736 and −509, −930 and −736 and −1512 and −951. Sucrose inducibility is controlled by sequences downstream of position −228, indicating that the tuber-specific and sucrose-inducible elements are in close proximity.

    Notes:
    Summary The cell content (protoplasm, chloroplasts, nuclei) ofBryopsis andPseudobryopsis can be accumulated in the tips of the branches by different agents — as hypertonic solution, centrifugation, neutral red staining. When the plants are cultured in sea water in all these cases inflation of the tips, local growth or thickening of the cell wall follows. The reaction of the plant depends on inner physiological conditions and varies with age and nutrition. The centrifuged cells ofHydrodictyon are a proof that a polynuclear cell does not behave as a physiological unity; a unilateral amassing of plasma and nuclei causes a local growth of one part of the cell; the centrifugal part of the cell inflates and the cell assumes the shape of a club. The experiments onBryopsis andPseudobryopsis show that the different parts of the coeloblasts show a high degree of independence and can develop in a special manner. The experiments show the possibility of correlation between the “concentration” — the quantitative distribution — of the cell content and the growth or thickening of the cell membrane. Revision and experimental analysis of the term “energide” bySachs appear to be necessary from these points of view.

    Zusammenfassung 1. Die Methode der Elektroinjektion wird beschrieben. 2. Diese Methode ermöglicht bestimmte Kationen in das Gewebe und die Zellen zu bringen ohne den gleichzeitigen Einfluß von zellfremden Anionen. Dies ist auch in lebenden Zellen möglich. 3. Mit dieser Methode können begrenzte Areale dem Einflusse der Kationen ohne Störung der natürlichen Lage ausgesetzt werden. Lokalisierte Schädigung oder Abtötung des Gewebes kann leicht erzielt werden. Die Verbreitung der in das Gewebe „injizierten“ Metalle kann dann mit Hilfe von chemischen Reaktionen verfolgt werden.

    Zusammenfassung Es wird einfache Methode beschrieben, die von S. Prát (1947) vorgeschlagen wurde. In Petri-Schalen werden Samen des Senfes (Sinapsis alba) auf Silongewebe aufgelegt und mit dem zu untersuchenden Wasser bewässert. Das Keimen der Samen, das Wachstum der Würzelchen sowie das Läangenvehältnis von Würzelchen zu dem Hypokotyl sind als Indikatoren der wasserbeschaffenheit anzusehen. Nicht nur die toxische Einwirkung, sondern auch Wasstumsförderung kann durch diese Testmethode ermittelt werden. Es wird vorgeschlagen, diese Methode besonders bei der Beurteilung des landwirtschaftlichen Zwecken dienenden Wassers und Abwasser anzuwenden, z. B. bei der Berieselung der Felder mit Abwasser, das nicht toxisch sein darf.
