Cytokinin metabolism: implications for regulation of plant growth and development

  • Břetislav Brzobohatý
  • Ian Moore
  • Klaus Palme


This review describes recent advances in the study of cytokinin metabolism. It highlights how plant development is influenced by cytokinin synthesis, conjugation and conjugate hydrolysis, and what has been learned of the enzymes that regulate these processes. Although cytokinin metabolism and physiology are complex issues, some of the key enzymatic players are now being identified. This holds out the prospect of rapid progress in the near future. Just as much of what we know about the control of animal cell proliferation was learned by studying the cellular counterparts of viral oncogenes, so important information about the control of plant development by phytohormones has come from studying the genes of bacterial pathogens that subvert host phytohormone metabolism to their own advantage. We will focus on what has been learned from the use of such genes, and describe progress in identifying their functional counterparts in plants.
