The effects of ABA and PtdOH on whole-cell K+-channel currents. (A) Families of current recordings from guard cells before (t = 0) and 15 min after (t = 15) treatment with 15 μM (+/−)-ABA or 50 μM PtdOH. Stable recordings were obtained for at least 20 min before each experimental treatment. Voltage was stepped in 20-mV increments from −160 mV to +60 mV. Representative traces are shown. (B) Current–voltage plots constructed from leak-subtracted K+ currents. Currents were measured 10–20 min after treatment with 15 μM (+/−)-ABA or 50 μM PtdOH (applied to the bath solution). Each plot shows the mean ± SEM for: control, n = 10; ABA, n = 9; PtdOH, n = 9.
