Cytokinin receptors from structural, evolutionary, and functional perspectives: a review.

Cytokinin receptors' structural features are still poorly understood despite their key roles in plant growth and development.

• Why it matters: Understanding receptor architecture is crucial for elucidating how cytokinin signaling influences plant biology and for developing targeted agrochemicals.
• What they did: The review synthesizes current knowledge on cytokinin receptors, focusing on their evolution, distribution, localization, ligand-binding, and biological functions, including plant-microbe interactions.
• The result: Linking structural features to receptor function may enable the design of selective agonists and antagonists, advancing plant biology research and agricultural applications.
