Comparison of KOR-mediated currents in two contrasting barley cultivars: salt-tolerant ‘CM72’ and salt-sensitive ‘Gairdner’. A, Frequency of detection (successful/total records) of KOR channels, average current densities at +60 mV, and average KOR current per protoplast. Means ± se (n = 36 for ‘CM72’; 70 for ‘Gairdner’). B, Voltage dependence of KOR-mediated conductance. Solid lines are best fits to Boltzmann equation, with midpoint potential values of 6.4 ± 1.4 mV and 9.6 ± 2.4 mV, and the slope factor (membrane depolarization that increases open/closed states ratio e times) of 18.6 ± 0.8 mV and 18.8 ± 1.2 mV for ‘CM72’ and ‘Gairdner’, respectively.
