Abstract :

Species of the Basidiomycota, class Agaricomycetes, order Polyporales, belonging to the diverse phlebioid clade, are among the most efficient saprotrophic fungal degraders of compact wood and wood lignocelluloses. The phlebioid clade includes species like Phanerochaete chrysosporium and Phlebia radiata, which are white rot fungi being able to attack and degrade even the recalcitrant lignin components in plant biomasses, and convert lignin-like xenobiotic molecules. With genomes of the phlebioid species available (P. chrysosporium, P. carnosa, Phlebia brevispora, P. radiata, Phlebiopsis gigantea, Bjerkandera adusta, we performed a comparative phylogenomic study on this clade with special emphasis on CAZy (Carbohydrate Active Enzymes), oxidoreductases (laccases, hemeincluding peroxidases, lytic polysaccharide monooxygenases) and hydrogen peroxide producing enzymes (GMC oxidoreductases, Cu radical oxidases). Transcriptomes and proteomic evidence of the species on lignocellulose substrates are compared, taking into account enzyme activity profiles and evolutionary diversification of the species to three distinct subclades within the phlebioid clade. Our aim is to find the enzymatic, genetic and genomic elucidation of the species diversification in this important fungal clade to different life-styles and growth patterns on wood and plant biomass, and find novel candidate genes for oxidative attack on lignocelluloses.
