Description	Cytokinin metabolism in plants is very complex. More than 20 cytokinins bearing isoprenoid and aromatic side chains were identified by high performance liquid chromatography-mass spectrometry (HPLC-MS) in pea ( Pisum sativum L. cv. Gotik) leaves, indicating diverse metabolic conversions of primary products of cytokinin biosynthesis. To determine the potential involvement of two enzymes metabolizing cytokinins, cytokinin oxidase/dehydrogenase (CKX, EC 1.5.99.12) and zeatin reductase (ZRED, EC 1.3.1.69), in the control of endogenous cytokinin levels, their in vitro activities were investigated in relation to the uptake and metabolism of [2-H-3] trans- zeatin ([2-H-3] Z) in shoot explants of pea. Trans-zeatin 9-riboside, trans-zeatin 9-riboside-5'-monophosphate and cytokinin degradation products adenine and adenosine were detected as predominant [2-H-3] Z metabolites during 2, 5, 8, and 24 h incubation. Increasing formation of adenine and adenosine indicated extensive degradation of [2-H-3] Z by CKX Cytokinin metabolism in plants is very complex.
