• Carrot (Daucus carota L.) cell suspensions were treated with a spirostanol saponin from Yucca. This saponin is an elicitor of callose synthesis. Irrespectively of the mode of action of spirostanol on the callose synthase activity itself, the spirostanol-induced callose synthesis in car-rot is not preceded by changes in membrane potential, cyiosolic free calcium or cyiosolic pH. The inability of modulators of cyiosolic free calcium content (verapamil, nifedipine and Br-A23187), EGTA and a proton pump inhibitor (vanadate) to inhibit or induce callose formation is consistent with a calcium- and pH-independent mechanism for callose deposition.
