Gene ontology (GO) enrichment analysis demonstrating the impact of silicon treatment and brown spot infection on primary metabolic processes in rice (LIMMA; false discovery rate < 0.01). For each GO term, the total number of genes represented on the microarray are shown, whereas the coloured bars indicate the relative number of genes showing a significant difference in expression across the different treatment comparisons (green bars, up‐regulation, log₂ fold change > 2; red bars, down‐regulation, log₂ fold change < −2). GO terms were derived from the MapMan database (Usadel et al., 2009). Si, silicon; Ctrl, control; I, inoculated; m, mock‐inoculated.
