Root Development: Cytokinin Transport Matters, Too!

Daniele Muraro, Michael Wilson & Malcolm J Bennett

Unlike the plant hormone auxin, the mechanism and function of cytokinin transport is poorly characterised. Two new studies now demonstrate that cytokinins transported from shoot to roots via the phloem are critical for creating mutually exclusive auxin and cytokinin signalling domains that control root vascular patterning.
