Zeatin encourages lateral bud growth, resulting in bushier plants. It stimulates cell division when sprayed on meristems. Terpenoid backbone biosynthesis produces dimethylallyl diphosphate which, with different reactants, can result in different products with a byproduct of diphosphate. When reacted with tRNA adenine via tRNA dimethylallyltransferase, it results in the formation of tRNA containing 6-isopentenyl adenosine. When reacted via adenylate isopentenyltransferase 1, chloroplastic with either ATP, ADP, or AMP, it results in the formation of the corresponding isopentenyl, which in turn reacts with oxygen and reduced NADPH hemoprotein reductase via cytokinin hydroxylase, resulting in the formation of trans-zeatin riboside with the corresponding phosphates and byproducts of water and oxidized NADPH hemoprotein reductase.
