Differentially expressed CAZymes during cultivation on xylan and wheat bran. a Fold change of gene expression during cultivation on xylan and wheat bran, compared to glucose. Upregulated genes (i.e. transcripts more abundant on xylan and/or wheat bran) are shaded green, downregulated genes (i.e. transcripts more abundant on glucose) are shaded red. b Fold change of transcripts more abundant during growth on xylan than on wheat bran (blue shading). c Fold change of transcripts more abundant during growth on wheat bran than on xylan (yellow shading). Shading is stronger for higher fold changes for all cases. Transcripts were considered significantly differentially expressed when fold change was at least two (p ≤ 0.05). Sec., genes encoding putatively secreted proteins. The prediction was done with two algorithms, SignalP 4.1 (black circles signify proteins with recognised signal peptide), and WoLF PSORT (blue circles signify proteins predicted to be secreted)
