Genome-Wide Transcriptome Analysis of Cadmium Stress in Rice

Figure 2

Distribution of upregulated and downregulated transcripts in roots and shoots in response to Cd exposure. RPKM fold changes at 1, 4, and 10 d were calculated for Cd-treated samples compared with nontreated samples (0 d). The total numbers of upregulated (upper) and downregulated (lower) transcripts in roots and shoots identified by RNA-Seq were determined by -tests (FDR < 0.01) at each stress time point (1, 4, and 10 d) under 0.2 μM (left) and 1 μM (right) Cd exposure. The -axis shows the time course and the -axis shows the number of transcripts.
