  • Salinity-induced ion flux patterns from the excised roots .

    Abstract. The SOS signal-transduction pathway is known to be important for ion homeostasis and salt tolerance in plants. However, there is a lack of in planta electrophysiological data about how the changes in signalling and ion transport activity are integrated at the cellular and tissue level. In this study, using the non-invasive ion flux MIFE technique, we compared net K +, H + and Na .

  • The Seed Biology Place - Seed germination

    Uptake of water by a mature dry seed is triphasic (see webpage "Water Relations"), with a rapid initial uptake (phase I, imbibition) followed by a plateau phase (phase II, metabolic preparation for germination). Phase III is a further increase in water uptake which occurs directly after germination is completed.

  • Genetic Analysis of Salt Tolerance in Arabidopsis .

    Double mutant analysis indicated that the SOS genes function in the same pathway. Based on these results, a genetic model for salt tolerance mechanisms in Arabidopsis is presented in which SOS1, SOS2, and SOS3 are postulated to encode regulatory components controlling plant K+ nutrition that in turn is essential for salt tolerance.
