Figure 7
Comparison of ratios of differential expression calculated by mRNA-Seq and microarray. For each gene from shoots (N = 14,575) and roots (N = 14,861), the ratio (log2) obtained from the array is plotted on the horizontal axis; the corresponding ratio obtained from RPKM (log2) is plotted on the vertical axis. The distributions of the number of transcripts are given outside the plot. Red line indicates where X = Y. Pearson's correlation coefficient is given in the corner of each plot.
