Norm of reaction of expression ratios (ER) for 6 genes from 73 hybridized microarrays of which the 35 presented in the cluster analysis (Fig. 3) are labeled with numbers. Distribution of log-transformed mean expression ratios of 4 genes of known function [proteinase inhibitor (PI), xyloglucan endo-transglycosylase (XTH), NtWRKY2 (WRKY) and allene oxide synthase (AOS)] and 2 of unknown function (540 and 434); dotted areas represent the arbitrary ER thresholds of 1.24 and 0.81 (corresponding to ± 0.3 for log2 transformed values). Genes are organized according to the relative spread of their expression ratios A > B > C. Insert in XTH panel shows error structure (mean ± SE) on a non-log scale calculated from 8 replicate spots from each array.
