Galactose (10 mM) inhibited IAA-induced cell elongation of oat coleoptiles but not that of Vigna angularis stems. Galactose decreased the level of UDP-glucose in oat coleoptiles but not in V. angularis hypocotyls. Glucose-1-phosphate uridyltransferase activity, in a crude extract from oat coleoptiles, was competitively inhibited by galactose-1-phosphate, but the enzyme from V. angularis was not.
