Ca(2+) current-deficient pawn mutants are promoted to queens during chronic depolarization of Paramecium tetraurelia.

The Journal of membrane biology - 1 Oct 1999

Preston R R, Hammond J A

Abstract excerpt

Chronic KCl-induced depolarization of Paramecium tetraurelia enhances Ca(2+)-dependent backward swimming behavior over a period of 8-24 hr. Here, we investigated the electrophysiological mechanisms underlying this adaptive phenomenon using voltage-clamp techniques. Cells that had been adapted to 20 mm KCl showed several significant changes in the properties of the Ca(2+) current that mediates ciliary reversal in...
