Clustering of genes in the Arabidopsis transcriptome. Out of 22,746 genes, 10,671 genes exhibited significant membership values in 180 clusters. The 17 most populated clusters include 7,039 genes (66% of total). Rows represent individual genes; columns (from left to right, as listed below) represent treatment conditions. A total of 180 clusters emerged. Outlined is cluster 12 (216 genes) including genes that responded to all stress treatment conditions (see Additional data files). (a) Time course experiments include cold (12 time points), osmotic (12), salt (12), drought (12), oxidative (12), and wounding (14) treatments. (b) Hormone treatments include ABA (3), ACC (3) and MeJA (3). (c) Biotic stress treatments include bacteria-derived elicitors (12), Pseudomonas syringae pt. tomato (Pst) DC300 (3), Pst avrRPM1 (3), Pst DC3000hrcC- (3), P. syringae pv. phaseolicola (3), Erysyphe oromoti (7), Phytophtera infestans (3), P. syringae ES4325 avrRPT2 (5), and P. syingae ES4325 (5). (d) Different light conditions (14). (e) Chemical treatments included t-zeatin, tri-iodobenzoic acid, AgNO3, and cycloheximide.
