a Data recovered from Genevestigator [19]. The data from experiment 106 are from the Nürnberger laboratory and experiments 146 and 147 are from the Ausubel laboratory. b Affymetrix probe set identifier for the ATH1 GeneChip. c Ratio of the average signal value for the given numerator treatment over the average signal value for the given denominator treatment. d ns, no signal. Less than 3 replicates with well measured values (i.e., p-value </= 0.06) available for the numerator, the denominator or both. e Expression levels from inoculated and uninoculated plants were significantly different (Student's t-test, p = 0.01).
