Plant Signaling: HY5 Synchronizes Resource Supply.
A new report shows that the HY5 transcription factor moves from shoots to roots in plants, mediating light regulation of root growth and nitrate uptake. This finding offers not only a mechanistic insight into shoot-root communication, but also scope for increasing crop yields.
