Abstract: | The dependence of protein kinase and RNA polymerase activities, and also of the synthesis of protein in nuclear chromatin, on the addition of benzylaminopurine and a cytokinin-binding protein to the incubation mixture has been investigated. It has been shown that all three processes are hormone-dependent. It has been found that the activity of protein kinase C is regulated by a cytokinin.A. S.
