IAA-glucopyranoside stimulation of corn coleoptiles elongation

Abstract


It has been previously suggested that 1-O-IAGIuc growth stimulation occurs as the effect of its hydrolysis into a free IAA. In present experiments castanospermine, a known β-glucosidase inhibitor, was included. 1-O-IAGluc in the presence of castanospermine stimulated growth of corn coleoptiles segments even stronger then free IAA. So, it seems that 1-O-IAGluc itself, is responsible for the observed stimulation of corn coleoptile segments elongation.
