Co-expression of <i>A</i>. <i>thaliana</i> pathway genes under stress.

<p><b>(A)</b> Boxplots of expression correlations (Pearson’s Correlation Coefficient, PCC) between pairs of genes in each <i>A</i>. <i>thaliana</i> metabolic pathway (left sub-figure) and random gene pairs (right sub-figure). The pathways are sorted based on median PCC. Light blue boxes: Interquartile range. Blue line: median PCCs. Red dashed line: the 95^th percentile PCC value (PCC95 = 0.41) of the random gene pair PCC distribution. Black dashed line: the median PCC of the random gene pair PCC distribution. <b>(B)</b> Bar plot indicating ECs for <i>A</i>. <i>thaliana</i> pathways (left sub-figure) and random gene pairs (right sub-figure). The pathways are in the same order as in (A). The insert graph shows the number of pathways that have significantly higher ECs than randomly expected (black) and those that are not significant (white). Different percentile thresholds on the x-axis are based on the random EC distribution (right sub-figure). The red dashed line designates the 95^th percentile of the random EC distribution.
