Description	Reversible glucosylation of zeatin-type cytokinins is important for the homeostasis of active cytokinin forms at certain developmental stages. Using the zeatin-O-glucoside (ZOG)-specific beta-glucosidase Zm-p60.1, we have been able to disrupt the zeatin metabolic network during early tobacco seedling development. The phenotypes of the progeny of crosses with tobacco plants over-expressing the glucosyltransferase ZOG1 were studied. The molecular and physiological changes underlying the observed phenotypes were discussed.
