Regulators of cell division in plant tissue. XXIII. The identity of an unusual metabolite of 6-benzylaminopurine.
When the cytokinin 6-benzylaminopurine was supplied to de-rooted radish seedings, the principal metabolites formed were the 7- and 9-glucosides. However the cytokinin activity of these glucosides was much less than that of a minor metabolite. This metabolite was purified (yield 550 mug from 40 600 seedings), identified as 6-benzylamino-3beta-D-glucopyranosylpurine and synthesized. It is the first compound with a glycosidic linkage at position 3 of a purine ring to be isolated from a plant tissue.
