Abstract excerpt
Cytokinins are of critical importance to numerous developmental processes in plants. Two cytokinin biosynthetic pathways have been described; each one uses a different type of isopentenyltransferases (IPTs) as the key enzyme. In the first pathway, adenylate-IPTs (EC 2.5.1.27) prenylate adenylic nucleotides to cytokinin nucleotides, thus catalysing the direct de novo biosynthesis of free cytokinins. In the second...
