FIG. 5.

Pheromone response after deletion of group I or group II genes. WT cells and the indicated mutant cells were transformed with the FUS1-lacZ reporter plasmid and treated with the indicated concentration of α-factor for 90 min. (A) Wild-type strain and group I control mutants sst2Δ and bar1Δ. (B) Wild-type strain and representative group I mutant asc1Δ. (C) Wild-type strain and the group II mutant cla4Δ. Data shown are typical of three independent experiments performed in triplicate. Error bars indicate SEM.
