Abstract

Single, giant cells of the eukaryotic green algae Chara braunii and Nitella flexilis were subjected to short-, intermediate-, and long-term irradiations with 2.45-GHz microwaves. A search was carried out for radiation-correlated shifts (i) in both the dc level and the rms low-frequency excess noise of the vacuolar potential and (ii) in the membrane resistivity. No reliable shifts were observed, either in normal cells or in cells subjected to reduced temperatures or the poison ethacrynic acid.

Main findings

Single cells of Chara braunii and Nitella flexilis were irradiated with 2.45-GHz microwaves for short, intermediate, and long durations. No reliable radiation-correlated shifts were observed in vacuolar potential (dc level), low-frequency excess noise, or membrane resistivity, including under reduced temperature or ethacrynic acid conditions.
