Structural basis for cytokinin recognition by Arabidopsis thaliana histidine kinase 4
Cytokinins are classic plant hormones that orchestrate growth, development and the integrity of stem cell populations. Cytokinin receptors are eukaryotic sensor histidine kinases that are activated both by naturally occurring adenine-type cytokinins and by urea-based synthetic compounds. Crystal str...

| Sumario: | Cytokinins are classic plant hormones that orchestrate growth, development and the integrity of stem cell populations. Cytokinin receptors are eukaryotic sensor histidine kinases that are activated both by naturally occurring adenine-type cytokinins and by urea-based synthetic compounds. Crystal structures of the Arabidopsis histidine kinase 4 sensor domain in complex with different cytokinin ligands now rationalize the hormone-binding specificity of the receptor and may spur the design of novel cytokinin ligands. |
