Pairwise gene co-expression statistic. Association of pairwise phylogenetic profile similarity, d_PP, and co-expression of Arabidopsis gene pairs as judged by their pairwise Pearson correlation coefficient, r_GE. Raw pairwise data are plotted as open circles, the red line indicates the linear regression line (r = 0.022, p = 2.9^*10⁻¹¹), the green line corresponds to a logistic fit virtually coinciding with the linear regression line, blue circles indicate median values of binned data (bin width = 0.1 d_PP units) connected by straight lines for visual guidance.
