Number of sets with <100, 100–500, 500–1000, 1000–2000 and >2000 regulated genes (>2-fold up- and >2-fold-down-regulated, p-value ≤ 0.05) with respect to their categorization (see section Re-evaluation and categorization of microarray experiments for further information). Categories: (1) WT condition A vs. WT condition B. (2) Plasmid-based gene overexpression in parental strain vs. parental strain with empty vector control. (3) Deletion mutant vs. parental strain. (4) Gene silencing strain vs. parental strain. (5) Promoter exchange strain vs. parental strain. (6) Producer strain vs. WT or other producer strain.
