title: Regulatory networks of gene expression in maize (Zea mays) under drought stress and re-watering
design: For the drought treatment, seedlings at the 3-fully expanded leaf stage were transferred to nutrient solution containing 20% polyethylene glycol (PEG) 6000. Leaves were harvested at 60 and 96 h of the drought treatment and after 3 d of recovery (denoted as T60, T96 and TR3d, respectively)
