Gene expression differences between Synechocystis sp. PCC 6803 and B12 in high-light. A Heatmap of the top 50 differentially expressed genes in Synechocystis transcriptome. The intensity of the orange/purple colours represents the normalised expression level. The rows have been sorted according to the gene clustering tree following Pearson correlation. The left-hand bar is colour-coded according to the functions of the genes. B Heatmaps representing gene expression differences between strains in normal N conditions for a set of significantly (p < 0.05) variable (LFC > 1) genes. In this comparison, B12 expression values are reported using PCC 6803 as reference. Red shadows indicate upregulated genes while blue is used for downregulated genes, with the scale bar showing LFCs. * indicates p < 0.05, ** p < 0.01 and *** p < 0.001
