Abstract:
:Although cytokinin plays a central role in plant development, our knowledge of the biosynthesis, distribution, perception and signal transduction of cytokinin is limited. Recent molecular-genetic studies have, however, implicated involvement of a two-component system in cytokinin signal transduction. Furthermore, new mutants with altered cytokinin responses and genes involved in cytokinin signaling have been identified.
