  1. Wild-type and exo plants were grown in soil in three independent experiments and gene expression profiling was carried out by means of Affymetrix ATH1 microarrays. Log2 fold changes (log2 FC) were determined from Col-0/exo signal ratios. A log2 FC ratio of one indicates a FC of two. FDR-adjusted P-values were calculated using the approach of Benjamini & Hochberg. Filtering criteria: average log2 FC ≥ 1 or log2 FC ≤ -1 and adjusted P-value ≤ 0.10.
