Membrane Electrical Noise in Chara corallina: I. A Low Frequency Spectral Component

S Ross et al. Plant Physiol. 1985 Dec.

Abstract

Some aspects of the membrane physiology of the giant-celled alga Chara corallina have been studied using the techniques of membrane noise analysis. Cellular voltage noise was measured by means of a microelectrode inserted in the vacuole of the cell. The significant feature of spectra estimated from voltage noise signals in these cells was a low-frequency component possibly associated with the active, electrogenic proton pumping which occurs in these cells. The effect of high external pH is described.
