Abstract

Synchronous secretion of all available mature mucocysts was induced in late log phase cultures of Tetrahymena thermophilia (B III) by the local anaesthetic dibucaine. No assembled fusion rosettes were seen within the plasma membrane after release until 2-3 hrs of regrowth, thus proving that the rosettes are not permanent sites within the plasma membrane but have to be reassembled each time for a new fusion event to occur. Concomitant with the reappearance of assembled fusion rosettes, the cell cytoplasm fills up with precursors of new mucocysts thus linking the two events together.
