FIGURE 7.

Seed priming regulated ZmNCED1 (A), ZmCYP707A2 (B), ZmSnRK2.1 (C), and ZmCPK11 (D) expression under chilling stress. Seed embryos were collected respectively at 0, 6, 24, 48 and 72 h after sowing, and six replications for each treatment at each sampling time were used. Different small letter(s) on the top of the bars indicated significant differences (p < 0.05, LSD) among treatments at same sown time. Error bars indicated ± SE of mean (n = 6).
