Fig. 5. Inhibition of anaerobic protein synthesis in detached rice coleoptile cells has destabilized mitochondrial fine structure. A, Under aerobic conditions (control). B, After 48 h anaerobic incubation without exogenous glucose. C, After 72 h anaerobic incubation in the presence of exogenous glucose (2 %). D, After anaerobic incubation in the presence of cycloheximide (10^–5 m) and glucose (2 %). m, Mitochondrion. Bars = 0·5 µm.
