Cytokinin (CK) activity is regulated by the complex interplay of their metabolism, transport, stability and cellular/tissue localization. O-glucosides of zeatin-type CKs are postulated to be storage and/or transport forms. Active CM levels are determined in part by their differential distribution of CM metabolites across different subcellular compartments. We have previously shown that overexpressing chloroplast-localized Zm-p60.1, a maize beta-glucosidase capable of releasing active cytokinins from their O- and N3-glucosides, perturbs CM homeostasis in transgenic tobacco.
