Up-regulated genes are especially enriched for regulators of DNA-dependent transcription. GO term analysis particularly highlighted the biological processes ‘regulation of transcription’, ‘chitin catabolic process’, ‘oxidation-reduction process’, ‘protein ubiquitination’ and ‘cytokinin metabolic process’, indicated by bold font. The color of the circles shows the significance level of each GO term (from yellow = P < 0.05 to red = P < 10–7), their size indicates the number of comprised differentially expressed genes
