Abstract
Cell free prepara-tions of the stem apical tissues of Coleus blumei Benth. plants, dwarf pea (Pisum sativum L.) and sunflower (Helianthus annus L. var. ''Mammoth Russian'' ) seedlings metabolize tryptophan-1-Cl4 with the release of C14O2. Pretreatment of the plants with gibberellic acid (GA) enhances the decarboxylation of either tryptophan or an indole intermediate of the tryptophan-indoleacetate pathways. The enhanced conversion rate of tryptophan precedes GA-induced stem elongation.This publication has 11 references indexed in Scilit:
