Study on Eu~(3+) on Channels in Radish (Raphanus satirus L.) Vacuoles by Patch-clamp

SHANG Yan-fang et al(School of Chemistry and Chemical Engineering,Nantong University,Nantong,Jiangsu 226000)  
[Objective] The effects of Eu3+ as rare earth fertilizers on physiological activities of plants were discussed at channel level.[Method] By using the whole-vacuolar patch-clamp recording mode,effects of cytosolic and luminal Eu3+ on SV-type channel currents of radish vacuoles were studied and discussed.[Result] When EGTA and EuCl3 were added to bath solutions,SV-type currents were suppressed remarkably.When bath solutions containing both CaCl2 and EuCl3 with different concentrations but free of EGTA,it was found that cytosolic Eu3+ had different promoting effects on SV channels.With the increase of the concentrations of Eu3+,SV-type currents decreased gradually.Finally the effects of luminal Eu3+ with different concentrations on the channel currents were studied in detail.It was found that EuCl3 with higher concentrations had strong inhibitory effect on SV currents,while EuCl3 with lower concentrations promoted channel currents.[Conclusion] These results provided an important basis at channel level for the further research on the effects of Eu3+ on physiological activities of plants and the optimum amounts of Eu3+ on crops as rare earth fertilizers.
