Previous studies have established that chlorella viruses encode K(+) channels with different structural and functional properties. In the current study, we exploit the different sensitivities of these channels to Cs(+) to determine if the membrane depolarization observed during virus infection is caused by the activities of these channels.

Infection of Chlorella NC64A cells by PBCV-1 produces a rapid depolarization of the host probably by incorporation of a viral-encoded K(+) channel (Kcv) into the host membrane. To examine the effect of an elevated conductance, we monitored the virus-stimulated efflux of K(+) from the chlorella cells. The results indicate that all 8 chlorella viruses tested(More)
