Research at channel level on the effect of LaCl3 on Radish (Raphanus satirus L.) vacuolar membrane
We recorded slow vacuolar (SV-type) channel currents of Radish vacuoles successfully for the first time by using the whole-vacuolar patch-clamp recording mode. SV-type currents would increase and thre
