Cytokinins are a class of plant hormones that play a crucial role in regulating various aspects of plant growth and development, including cell division, shoot and root development, and leaf ...

For multicellular organisms, long-distance communication is essential for coordination of organ growth and development. In higher plants, a dual root-to-shoot cytokinin signalling system plays a ...

Legumes regulate the number of nitrogen-fixing nodules on their roots through long-distance root–shoot communication. Here, Sasaki et al. identify shoot-derived cytokinins, produced downstream ...
