Metagene 1,3 and 5 Activity in Biological Processes. This heat map shows the biological process NES score for metagenes 1, 3 and 5. Bright red cells indicate high enrichment within an ontology. Metagene 3 is highly enriched with respect to different responses related to chemical and mechanical stimulus. Metagene 5 is enriched with respect to defense responses such as light and bacterial infection. Metagene 1 is also enriched in catabolic processes related to toxin removal, which one would expect for a metagene active under the stress series of experiments.
