Figure 5. Expression patterns of Cd-upregulated heavy metal ion transporters in various medium conditions by qRT-PCR analysis.

Figure 5

The expression of Cd-upregulated heavy metal ion transporters was investigated in various liquid media containing different kinds of metal ions by qRT-PCR analysis. The x-axis shows treatments and the y-axis shows relative expression. Transcript expression levels were normalized using an internal control (ubiquitin 1) and plotted relative to expression in water (control) at 24 h in roots (R) and shoots (S). The transcripts were classified into four groups based on their expression patterns.
