Complementation with CgSTB5 abrogates the sensitivities to caffeine and cold in the Δyhr178w mutant. (A) Growth on YPD agar plates at 30°C. (B) Growth in the presence of 0.15% caffeine. (C) Growth on YPD agar plates at 20°C. For strains, see Table 1. Cells were diluted to 1 × 10⁵ cells per 5 μl, followed by four 1:10 dilutions, and 5 μl of diluted cell culture was spotted on YPD or YPD with 0.15% caffeine agar plates and incubated at 30°C or 20°C for 48 h.
