Fig. 3From: Expression of Aspergillus niger CAZymes is determined by compositional changes in wheat straw generated by hydrothermal or ionic liquid pretreatmentsHeatmap of hierarchical clustering of CAZy transcript patterns by condition. The conditions were clustered using the log-transformed and quartile-normalised mean FPKM values of CAZy genes, excluding genes whose expression was not ≥1 FPKM in any of the time points on any media. The clusters 1–5 are referred to in the main text. A heatmap of the clustering of the conditions using the signal peptide annotated gene FPKM values can be found in Additional file 2: Table S1Back to article page
