摘要：

Cell-free extracts of immature Zea kernels incubated with tritiated AMP and DMAPP produced the cytokinins Delta(2)-isopentenyladenosine and its monophosphate. The products were identified on the basis of extensive HPLC analysis of both the compounds themselves and derivatives. The results suggest that the primary reaction in cytokinin biosynthesis in higher plants is mechanistically similar to that of the Agrobacterium DMAPP:AMP transferases.
