Current/voltage relations of whole-cell inward
K+ currents with adaxial and abaxial guard cell protoplasts
with or without 1.0 μm ABA in the pipette solutions.
K+ current amplitudes are expressed as the current per unit
cell capacitance to correct for variations resulting from different
cell sizes. The number of replicates for each treatment were 9 (Ad,
Control), 14 (Ad, ABA), 6 (Ab, Control), and 10 (Ab, ABA). Each data
point is the mean ± se.
