Abstract excerpt

Cytokinins, which are central regulators of cell division and differentiation in plants, are adenine derivatives carrying an isopentenyl side chain that may be hydroxylated. Plants have two classes of isopentenyltransferases (IPTs) acting on the adenine moiety: ATP/ADP isopentenyltransferases (in Arabidopsis thaliana, AtIPT1, 3, 4-8) and tRNA IPTs (in Arabidopsis, AtIPT2 and 9). ATP/ADP IPTs are likely to be...
