Genome-Wide Transcriptome Analysis of Cadmium Stress in Rice

Figure 4

Expression profiling of metal ion transporter genes in roots and shoots under Cd exposure at 1 d demonstrates Cd concentration-dependent differences. Heatmap analysis of metal ion transporters containing Pfam domains [PF01554 (MatE), PF08370 (PDR_assoc), PF01545 (Cation_efflux), PF02535 (Zip), PF00403 (HMA), and PF01566 (Nramp)]. The relative expression values under 0.2, 1, and 50 μM Cd (data from [4]) are presented. The color scale shows log2-transformed transcript levels for each gene.
