FIG 7.
Fluconazole susceptibilities of the wild-type strain SC5314 and of mrr1Δ, tac1Δ, and upc2Δ mutants expressing the indicated hybrid transcription factors. *The MIC for one of the two independently constructed upc2Δ mutants expressing the MRR1DB-UPC2 fusion was slightly lower (4 μg/ml). In all other cases, the two independently generated strains behaved identically.
