Hierarchical clustering of stress array expression data by treatment, including results of insect feeding and pathogen infection experiments. Eleven clusters were evident: 1, response to brassinosteroid; 2, Freeze/heat stress responses; 3, Cold/Cytokinin stress responses; 4, responses to three insect treatments/jasmonate signaling; 5, Drought stress responses; 6, NaCl stress response; 7, responses to oxidative stresses/wounding; 8, late responses to P. syringae and responses to Rpm24, DC30 bacteria; 9, salicylate-mediated responses to microbes; 10, responses to aphids and early response to P. syringae; 11, suite of responses to 4 hormones. Key to treatments: BR, brassinosteroid; Frez, freezing; heat, heat; cold, cold; BA, 50 μM 6-benzyladenine (synthetic cytokinin); JA, 50 μM jasmonic acid; spod, Spodoptera exigua; drt, drought; ABA, 50 μM abscisic acid; Mann, 300 mM mannitol; NaCl, 300 mM NaCl; PQ, paraquat; Wou, wound; 3AT, 4 mM 3-amino-1,2,4-triazole; GGO, glucose-glucose oxidase; XXO, 2 mMxanthine-xanthine oxidase; Psyringae, Pseudomonas syringae pv. tomato; RPM, Pseudomonas syringae pv. tomato DC3000 (avrRpm1); DC30, P. syringae pv. tomato DC3000; Alt, Alternaria brassicola; Sen, senescence; TCV_72, turnip crinkle virus; SA, 2 mM salicylic acid; Brev, Brevicoryne brassicae; Myzus, Myzus persicae; 24D, 50 μM 2,4-dichlorophenoxyacetic acid (synthetic auxin); IAA, 50 μM indoleacetic acid; ACC, 50 μM 1-aminosyclopropane-1-carboxylic acid (ethylene precursor); GA, 50 μM gibberellic acid. Details of the experimental treatments are found in Mahalingam et al. (2003).
