%X Patch clamping whole-cell recording techniques were applied to study the inward K -channels in ,Ara-bidopsis root cortex cells. The inward K -channels in the plasma membranes of the root cortex cell protoplasts were activated by hyperpolarized membrane potentials. The channels were miglv selective tor K ions over Na ions. The channel activity was significantly inhibited by the external TEA , or Ba2 The changes in eytoplasmic Ca2 concentrations did not affect the whole-cell inward K -currents. The possible asoeiation between the ehannel selectivity to K and Na ions and plant salt-toleranee was also discussed.
