highly significantp = 2.24 e-11
Functional enrichment analysis of this set of 46 genes using FatiGO ( http://babelomics.bioinfo.cipf.es ) revealed a highly significant enrichment (Fisher exact test, two-tailed, p = 2.24 e-11 ) for genes annotated with gene ontology (GO) term GO:0006952 (defense response), with 39.1% (18/46) of the upregulated genes associated with this term, compared to 2.61% in the whole Arabidopsis genome.
