Comparison of RPKM of each gene after salinity stress. RPKM values for 29,389 RAP2 representative transcripts in the presence or absence of salinity stress were compared in the shoot (left) and root (right). For each gene, the RPKM (log₂) value without salinity stress is plotted on the horizontal axis, and the corresponding RPKM (log₂) value with stress is plotted on the vertical axis. Distributions of the number of transcripts are given outside the plot. The number of highly differentially expressed genes was greater in the root than in the shoot. Pearson's correlation coefficient is given in the corner of each plot.
