FIGURE 10.

Single-channel recordings in outside-out patches of T. halophila root protoplasts. The pipette solution was 100 mM KCl. The bath solution contained 100 mM KCl (A), 10 mM KCl (B) or 100 mM NaCl (C). c, current level with no open channels; o, current levels of single-channel openings. Spiky openings of outward-rectifying channels allowing inward current are indicated with asterisks. Openings of a second type of channel are indicated with crosses.
