FIGURE 4: Stress phenotypes of t⁶A-deficient strains differ from a mcm⁵s²U-deficient strain.

Cells were grown at 30°C for 48 hours on YPD with 2% glucose except when 6% ethanol or 3% glycerol was used as a sole carbon source or heat stress at 37°C. Drugs were added to YPD at the following levels: L-homoserine, 1 mg/mL; Rapamycin, 10 nM; Phleomycin, 8 µg/mL; caffeine, 10 mM; carmustine, 1 mM; NaCl₂, 1 M.
