Heatmap, scatter, and volcano plot of DEGs of Planomicrobium-AX6 transcriptome data, exposed to hydrogen peroxide for 4 h under H₂O₂ (1.5 mM). A Scatter plot. The horizontal and vertical coordinates have logarithmic values, indicate the expression levels (FPKM value) of genes in the AX6 and CK. B Volcano plot. Each colored point in the volcano plot represents a single gene. Plotted along the x-axis is the log2 fold change of each gene. The y-axis represents the negative logarithm of the corresponding P-value of that gene. C Heatmap. The scale bar shows the z-score for a differentially expressed gene. The color represents the amount of gene expression in the group of samples (log.¹⁰ FPKM), referring to the color key at the upper left. D Line plot. The sub-cluster of the heatmap represents a gene, and the blue line represents the average expression of all genes in the sub-cluster. CK designate RNA sample replicates obtained from Planomicrobium-AX6 without H₂O₂ (1.5 mM) for 4 h, whereas AX6 is RNA sample replicates obtained from Planomicrobium-AX6 with H₂O₂ (1.5 mM) for 4 h.
