Grasses suppress shoot-borne roots to conserve water during drought. Setaria viridis

Setaria viridis, the wild ancestor of millet, exhibits strong repression of crown root growth in drought. We compare in gene expression in the S. viridis crown between drought vs watered treatments. Overall design: RNA from Lower region (crown) or Upper region (stem) of watered (W) or drought (D) treated Setaria plants were harvested at 6 or 9 days after sowing; there are 8 samples per biological repeat, 3 biological repeats.
