Short Communication


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.
