Light-induced Polysome Formation in Etiolated Leaves: Kinetics of Inhibition by Antibiotics 1

Klein, Attila O.

RESUMO

Red light-induced, far red light-reversible increase in etiolated bean (Phaseolus vulgaris, var. Asgrow Valentine) leaf polyribosomes was shown to be sensitive to actinomycin D, cycloheximide, and rifampicin inhibition. Actinomycin prevented response to red light if administered simultaneously with a 10-minute illumination, had no immediate effect if given 2 hours after illumination, but was again rapidly inhibitory at 4 and 6 hours. The effects of actinomycin and far red light were more than additive.
