Comparison of high-conductance K+-permeable channel activity in the tonoplast of N. obtusa in the control solution ACS and after application of 300 µM verapamil, 75 µM NED-19, and 200 µM tetrandrine. (a) Examples of current traces obtained at −80 mV. Dashed lines indicate open states. The measurements were prepared in the tonoplast-attached configuration. Single channel I/V curves obtained after exposure to 300 µM verapamil (b), 75 µM NED-19 (c), and 200 µM tetrandrine (d). Asterisks indicate significant differences, n = 5−9.
