Strains harboring a 4xCDRE-lacZ construct were cultured in the absence or presence of 64 μg/ml fluconazole, and with or without 10 μM geldanamycin, 1 μg/ml FK506 (in DMSO, A. G. Scientific), or 20 μg/ml beauvericin. Strains were grown in synthetic defined (SD) media at 25°C overnight and diluted the next day to OD600 0.01 ± inhibitors geldanamycin, FK506, or beauvericin. Cultures ± inhibitors were again incubated overnight in SD at 25°C and diluted the next day to OD600 0.3 ± inhibitors in the presence or absence of fluconazole for five hours. Strains harboring the HSP70-lacZ construct were treated with 10 μM geldanamycin or 10 μg/ml beauvericin. Strains were grown in YEPD at 30°C overnight and diluted the next day to OD600 0.01 ± inhibitors geldanamycin or beauvericin. Cultures ± inhibitors were again incubated overnight in YEPD at 30°C and diluted the next day to OD600 0.2 ± inhibitors for four hours. Post-treatment sample processing and analysis was conducted as previously described10 (link).
