Cytokinin action: two receptors better than one?
Cytokinins are ubiquitous plant hormones that have dramatic effects on growth and development, but almost nothing is known of their molecular mode of action. Recently, evidence has emerged that cytokinin action may involve a G-protein-coupled receptor and/or a two-component signaling pathway.
