Fig. 2: Gene expression in B. salamandrivorans.

a Co-expression Venn diagram presents the number of genes that are uniquely expressed within each group per sample, with the overlapping regions showing the number of genes that are co-expressed in two or more groups per samples. b Volcano plots of differentially expressed genes identified between the galactose, glucose, or mannose group and control group. The green dots denote downregulated gene expression, the red dots denote up-regulated gene expression, and the blue dots denote the gene expression without marked differences. c FPKM cluster analysis, clustered using the log₁₀ (FPKM + 1) value. Blue denotes genes with high expression levels, and red denotes genes with low expression levels. The colour ranging from blue to red indicates log₁₀ (FPKM + 1) value from large to small. Trees indicate hierarchical clustering between data sets (above) and genes (left of heatmap). Gal = galactose; Glc = glucose; Man = mannose. Source data are provided as a Source Data file.
