Courtship in S. cerevisiae: both cell types choose mating partners by responding to the strongest pheromone signal.

Abstract excerpt

We demonstrate that during the courtship stage of conjugation, S. cerevisiae a cells choose the alpha cell producing the highest level of pheromone from among potential mating partners. From this result and that for alpha cells we conclude that both a and alpha cells act as signaling cells during courtship, that both cell types respond by discriminating different levels of signal, and that the signals are the...
