Interaction of cycloheximide and light on chlorophyll content and chloroplast ultrastructure inBrassica campestris

Cycloheximide retarded the loss of chlorophyll from detached komatsuna (Brassica campestris cv. Komatsuna) leaves during incubation in the dark but promoted its loss in light. Cycloheximide-induced chlorophyll bleaching in light was prevented by some active oxygen scavengers. Chloroplast envelopes of cycloheximide-treated leaves incubated in both the dark and light were destroyed within 48 h. The grana of cycloheximide-treated leaves incubated in light were dilated.
