Abstract
Single ion channels with different conductances and gating characteristics were observed in the plasma membrane of the slime mold Dictyostelium discoideum by means of the patch-clamp technique in the cell-attached mode. The predominant channel type shows outward current flow, probably carried by K+ ions. The slope conductance of this channel is 9 pS and its probability to be open increases with depolarization of the membrane. The channel is observed from 1 to 8 h after the beginning of starvation.
