Bioinformatic analysis of FfCEL6B. a Schematic diagram of fCBD domain of FfCEL6B. b fCBD protein sequence alignment. fCBD homologous proteins are from Pleurotus cornucopiae, Coprinopsis cinerea, Pleurotus eryngii, Flammulina velutipes, Armillaria ostoyae, Armillaria solidipes, P. ostreatus, Flammula alnicola, Pleurotus pulmonarius, Armillaria gallica, Agrocybe aegerita, and Lentinula edodes. Asterisks represent conserved amino acids. c Phylogenetic relationships between FfCEL6B and sequence alignment species. The triangle denotes FfCEL6B in F. filiformis. d Schematic representation of major cis-acting elements in the FfCEL6B promoter. “ + ” denotes the sense sequence and “−” represents the antisense strand
