Abstract
Using etiolated Alaska pea internode segments the following results were obtained. An auxin, 2,4-dichlorophenoxyacetic acid, 1 mg/liter, induced the elongation growth of the segment and stimulated the biosynthesis of RNA, particularly of messengar RNA, in 3 hr incubation. The similar stimulation of RNA synthesis and of elongation due to indole-3-acetic acid was found in 1 hr incubation. The stimulative effect of 2,4-dichlorophenoxyacetic acid on the elongation and on the synthesis of messenger RNA was inhibited by the addition of an antiauxin, transcinnamic acid. Significance of the auxin-induced synthesis of messenger RNA in producing protein responsible for the stress relaxation of cell wall is discussed.
