Fig. 2From: Long-term soil metal exposure impaired temporal variation in microbial metatranscriptomes and enriched active phagesMetatranscriptomic pairwise ratio comparison of gene expression in the three plots. The figure shows the log10 up and downregulation ratios of functions within metabolic categories in Cu-plots relative to the control (panels a and b, downregulated = higher in the control; upregulated = higher in the copper plots), and between copper plots (panel c, downregulated = higher in the semi-contaminated; upregulated = higher in the hotspot). Absolute mRNA counts of functions significantly altered by Cu were extracted (nbGLM, LRT, FDR-corrected p < 0.05), summed per metabolic category, and respectively divided by either control plot values (panels a and b) or from the semi-contaminated plot (panel c) in order to define relative up and downregulation ratios. The displayed functional categories used are very large and encopass many subcategories and genes. Therefore, within a same category, some genes might be significantly upregulated while others might be downregulatedBack to article page
