Figure 12.
Expression profiles of 12 selected OsHMPs in response to Cu2+(A), Cd2+(B), Zn2+(C), and Pb2+(D) stresses in 2-weeks old rice seedlings after treatment for 1, 3, 12, and 24 h. Data represent means (±SD) of three biological replicates. Vertical bars indicate standard deviations. Asterisks indicate corresponding genes significantly upregulated or downregulated between the treatment and control (n = 12, *p < 0.05; **p < 0.01; Student's t-test).
