    Guard cells undergo constitutive and pressure-driven membrane turnover

    During stomatal movement, guard cells undergo large and reversible changes in cell volume and consequently surface area. These alterations in surface area require addition and removal of plasma membrane materi...

    Transient and Permanent Fusion of Vesicles in Zea mays Coleoptile Protoplasts Measured in the Cell-attached Configuration

    Exocytosis in protoplasts from Zea mays L. coleoptiles was studied using patch-clamp techniques. Fusion of individual vesicles with the plasma membrane was monitored as a step increase of the membrane capacitanc...

    Cl− and K+ channel currents during the action potential in Chara. simultaneous recording of membrane voltage and patch currents

    Patch currents in the cell attached-mode and action potentials (AP) have been recorded simultaneously in internodal cells of Chara corallina. The action potentials are closely correlated with transient patch curr...
