Expression data from root segments of barley (Hordeum vulgare) during a transient water deficit repressing lateral root formation

In the lateral root repression system described by Bab et al. (2012), the first asymetric divisions of pericycle cells preceding lateral root formation are repressed during water deficit treatments. During an 8-hr long treatment, an 8-mm long root segment is formed where LR formation has been repressed.
