Abstract

Summary: Rhodotorucine is a mating pheromone produced by mating type cells of which induces mating tube formation in mating type cells. Rhodotorucine induced conspicuous changes in Ca fluxes in the target cells which consisted of a very rapid, transient Ca influx immediately after pheromone addition and a gradual Ca accumulation during mating tube elongation. The magnitude of the pheromone-induced changes of Ca fluxes was correlated with the efficiency with which the pheromone elicits biological responses in mating type cells. Compared to vegetative growth, the response to the pheromone was highly sensitive to trifluoperazine, an inhibitor of calmodulin. Trifluoperazine inhibited exclusively the emergence and the elongation of mating tubes but not the signalling reaction.
