Abstract

Benzyladenine, a synthetic cytokinin, stimulates DNA metabolism during maize germination; apparently such stimulation occurs in two phases, and during the first phase stimulations of DNA synthesis, of protein kinase activity (both α-amanitin repressible), of DNA polymerase and poly ADP-ribosyl polymerase activities are observed. Since the evidence suggested that the effects produced by BA were due, at least partially, to transcriptional activation, attempts were made to discover genes, by subtractive hybridization of a cDNA library or by differential display, whose expression depended on the presence of BA; however these were unsuccessful. BA modulated the expression of a limited number of genes only. The possible mechanism by which BA could be promoting DNA metabolism during maize germination is discussed.
