Fig. 1
Principal component analysis (PCA) of normalized transcription levels of GH families. Normalized FPKM values of GH families under different growth conditions were used as input. Stars represent growth substrates and arrows represent GH families. Growth substrates with similar transcriptional profiles are closer together in the ordination plot than substrates with different transcriptional profiles. The direction of arrows in the biplot is indicative of the respective maximal transcription, while the length of the arrows is indicative of the differential transcription
