Expression patterns of ZmNAS genes under various environmental Zn, Cu and Mn status. The maize seedlings were hydroponically cultured to three-leaf stage, and then they were transferred to Hoagland solution with 200 μM ZnSO4 or without indicated metals. The shoots (S) and roots (R) were harvested after 0, 6, 12, 24, 48 and 96 hours of treatment. Relative genes expressions were normalized using maize Actin1. The error bars indicate standard deviations.
