Fig. 6

Expression of ten OsZIP genes in roots of OsLCT2 overexpression lines and the WT. Seedlings were exposed to 0 or 0.5 μM Cd for 24 h. Expression levels were determined by qRT-PCR. Expression levels relative to WT without Cd treatment are shown as means ± SD of three biological replicates. Different letters above the bars indicate significant differences at P < 0.05 (one-way ANOVA, Tukey’s test)
