Table II.

Frequency of occurrence of anion currents in protoplasts isolated from maize stelar parenchyma cells and the mean current densities, averaged from all protoplasts

Current densities were measured at −120 mV in the plasma membrane of protoplasts suspended in 20 mm CaCl2 (solution ESB), with the patch clamp pipette containing 50 mm TEA-Cl and a [Ca2+]cyt of 100 nm (solution ISC). Means provided with SEM, n = 15.
