(A) WT and atg1Δ cells grown in YEPD medium were transferred to SD-N +50 mM MES-KOH (pH 6.2). After 120 hours, cultures were diluted 5.0×105 fold and plated onto YEPD agar. The plates were incubated at 30°C for four days. Insets indicate the plate overlaid with TTC agar to examine the respiratory competency of formed colonies.
