FIGURE 1.

Transcript accumulation of ZmLEA3 in maize stems. The maize seedlings were incubated with Hoagland’s solution for 2 weeks; uniformly sized plants at similar growth stages were chosen for further study. The total RNA was isolated from the stems. Maize seedlings were treated with 4°C (A), 10 mM H₂O₂ (B), 100 μM abscisic acid (ABA) (C), 20% polyethylene glycol (PEG) 6000 (w/v) (D), or water (control) (E). Total RNA was isolated from the stems at the indicated times after the treatments. Each curve/column represents an average of three replicates, and error bars represent standard deviation. R represents removal of the treatment.
