Figure 4

Examples. Each of the three rows presents an example of cross-hybridization. Each time, the first of the plots (A-D-G) shows the summarized expression values of probe set X (in blue) and probe set Y (in orange) in 14 different plant tissues. The plots in the second column (B-E-H) present the background corrected, normalized expression patterns of X's reporters. The signal profile of the reporter is plotted in a color that corresponds to its alignment score to Y and is explained in the legend of plot B. In the third column (C-F-I) for each of X's reporters, ${\rho }_{X_{i}Y}$, calculated between its signal profile to that of Y, is plotted against its alignment score, $a_{X_{i}Y}$. Colors correspond to those used in the plot in the second column.
