Figure 3

Representation of the cis-element enrichment and the expression kinetics in the different clusters. The left panel shows clusters sharing cis-elements. The cluster number and the number of genes of each cluster (in brackets) are shown on the left. The right panel represents the kinetic behaviour of the clusters as predicted by the comparison with publicly available data on ‘late’ flg22-regulated genes. Class F genes are induced after 1 h flg22 treatment and return to basal level after 3 h. Class G genes are induced after 1 h flg22 treatment and induced to a lesser extent at 3 h after treatment. Class H genes are induced after 1 h flg22 treatment and to a same extent at 3 h. Class I genes are induced after 1 h flg22 treatment and show further induction at 3 h. Class J genes are not induced at 1 h but show upregulation 3 h after flg22 treatment. Class A, B, C, D, E show the same tendencies but with flg22-induced downregulation. No cis-element enrichment was found for clusters 1, 2, 3, 5, 9, 17, 21. Clusters 1, 4 and 7 do not show significant enrichment in ‘late’ flg22-regulated genes.
