Fig. 3From: Trees, fungi and bacteria: tripartite metatranscriptomics of a root microbiome responding to soil contaminationSalix purpurea differential expression (DE) transcript distribution and abundance (transcripts per million, tpm) weighted fold change (log2). Top: fold change (FC log2) distribution of DE genes contaminated (black) and non-contaminated (gold). Bottom: mean transcript counts (tpm) difference between conditions against fold change per DE contig. The highly abundant transcripts discussed within the text are labelled. A full DE transcript list including expression data, functional description (if available), gene ontology terms (if available) and secondary annotation (if available) is provided in Additional file 5.
