Transcription of cellulolytic genes disaggregated by genome. Transcription of cellulolytic genes disaggregated by genome. The top 3 genomes transcribing each gene class of interest at each IL concentration were pooled into a list of 28 genomes as shown on the right side of the heat maps. The phyla of the genomes are colored on the left side of the heatmaps for easier identification and are explained in the legend at the top of the figure. Transcription is shown for (A) endoglucanases and (B) xylanases. Yu-Wei Wu et al. mSystems 2016; doi:10.1128/mSystems.00120-16
