Popis: The response of stems to GABA was biphasic in that lower concentrations of GABA (upto 500 µM) promoted stem elongation, but higher concentrations of GABA inhibited stem elongation. An optimal GABA concentration of 250 µM produced maximum stem elongation. The higher GABA concentrations also stimulated 1-aminocyclopropane-1-carboxylate (ACC) synthase (EC 4.4.1.14) mRNA accumulation and ethylene production. Results suggest that the inhibitory effect of higher GABA concentrations on stem elongation is partly mediated by ethylene.
