Different expression profiles of ligninolytic enzyme genes. a Venn diagram showing differentially expressed genes by comparing LC3d versus Glu3d (Blue) and LC6d versus LC3d (Red). The numbers of gene with transcript levels changing ≥ 2-fold were shown. LC3d: lignocellulose, day 3; LC6d: lignocellulose, day 6; Glu3d: glucose, day 3; Glu6d: glucose, day 6. b Phylogenetic analysis of the class II peroxidases and DyPs identified from the genome of I. lacteus CD2. The five MnP genes up-regulated in lignocellulose culture (day 3) were highlighted in green. c Gene expression profiles for the ligninolytic enzymes associated with lignin modification under the four culturing conditions
