To assess the extent of water flow through channels in the membranes of intact higher plant cells, the effects of HgCl2 on hydraulic conductivity (LP) of wheat (Triticum aestivum L.) root cells were investigated using a pressure probe. The LP of root cells was reduced by 75% in the presence of 100 &mgr;M HgCl2. The K+-channel blocker tetraethylammonium had no effect on the LP at concentrations that normally block K+ channels. HgCl2 rapidly depolarized the membrane potential (Vm) of the root… CONTINUE READING
