Variable Gene-Network Expression Responses in Pairwise Comparisons of Six Accessions with Col-0.

To investigate relationships between gene networks that showed variation in the pairwise ANOVAs, we used the LCF multidimensional gene-network relationship shown in Supplemental Figure 4D online as a framework for comparison of Col-0 to the other six accessions. We included only those networks that were induced by SA. For each pair of accessions, the gene networks with statistically significant variation are indicated as black, gray, or hatched nodes. Black and gray nodes indicate gene networks with differential expression between the two accessions after SA or control treatments, respectively. Hatched black/gray nodes indicate those networks with differential expression between the two accessions under both treatment conditions. Black lines connect nodes showing variable expression. Nodes for gene networks that were not significantly different are in white and connected by gray lines. The statistical identification of pairwise network differences is shown in Supplemental Figure 5 online.
