  • To deepen the understanding of cytokinin's role in plant development.

Main Methods:

  • Utilizing molecular-genetic approaches.
  • Analyzing newly identified mutants with altered cytokinin responses.
  • Investigating genes associated with cytokinin signaling pathways.

Main Results:

  • Evidence implicating a two-component system in cytokinin signal transduction.
  • Identification of novel mutants affecting cytokinin responses.
  • Discovery of new genes involved in the cytokinin signaling cascade.

Conclusions:

  • Recent molecular-genetic studies have significantly advanced the understanding of cytokinin signaling.
  • The involvement of two-component systems is a key finding in cytokinin perception and response.
  • Further research on identified mutants and genes will continue to unravel cytokinin's complex roles in plants.
