Comparison of the transcriptional response of the ∆blu7 and WT strains under constant white light. a Boxplot of differential light regulated genes with |log2FC| > 1 for the ∆blu7 and WT strains. b Overall plot of log2FC of the light regulated genes in WT vs ∆blu7. Hierarchical clustering results in 8 clusters (I, II, III, IV and V up-regulated and VI, VII and VIII for down-regulated). Horizontal lines of ±1 contain the genes differentially expressed only in the WT strain; vertical lines of ±1 contain the genes differentially expressed only in the ∆blu7 mutant. c BLAST2GO annotation of the light regulated genes in WT or ∆blu7 by biological process (PB), molecular function (MF) or cellular component (CC). d Venn diagram showing the overlap in up-regulated (left) and down-regulated (right) genes that respond in the WT and ∆blu7 mutant strain
