  • Rapid membrane potential responses for gravistimulation in bean roots.

抄録

The membrane potential distributions and the dynamic changes of two day old bean roots under gravistimulation were shown by glass-micro electrode techniques. The electrodes held by three dimensional hydraulic micro-drives were strictly inserted into elongating cortical cells. Membrane potentials, root inclinations and the position of the cortical cells were measured simultaneously.<BR>Gravistimulus electrogenic components were distribute in the elongating region and these electric distributions were reconstituted within 30sec of the gravistimulation changes. The reconstitution was more rapid than the hormonal translations.
