Structural and Biological Links between Urea- and Purine-cytokinins

抄録

Structural and biological correlation between two classes of cytokinins, purine- and urea-cytokinins, were discussed. The biological response in the presence of competitive antagonists of cytokinins suggested that benzyladenine and N-(4-pyridyl)-N'-phenylurea have a common active site for the growth of tobacco callus.
