Journal ArticleDOI

The paleozoic origin of enzymatic lignin decomposition reconstructed from 31 fungal genomes

Dimitrios Floudas, +70 more
- 29 Jun 2012 - 
TL;DR: Comparative analyses of 31 fungal genomes suggest that lignin-degrading peroxidases expanded in the lineage leading to the ancestor of the Agaricomycetes, which is reconstructed as a white rot species, and then contracted in parallel lineages leading to brown rot and mycorrhizal species.
Journal ArticleDOI

Genome sequencing and analysis of the biomass-degrading fungus Trichoderma reesei (syn. Hypocrea jecorina).

TL;DR: This work assembled 89 scaffolds to generate 34 Mbp of nearly contiguous T. reesei genome sequence comprising 9,129 predicted gene models, providing a roadmap for constructing enhanced T.Reesei strains for industrial applications such as biofuel production.
Journal ArticleDOI

Genome, transcriptome, and secretome analysis of wood decay fungus Postia placenta supports unique mechanisms of lignocellulose conversion

TL;DR: Comparisons with the closely relatedwhite-rot fungus Phanerochaete chrysosporium support an evolutionary shift from white-rot to brown-rot during which the capacity for efficient depolymerization of lignin was lost.
Journal ArticleDOI

The Plant Cell Wall–Decomposing Machinery Underlies the Functional Diversity of Forest Fungi

TL;DR: Fungal nutritional mode diversification suggests that the boreal forest biome originated via genetic coevolution of above- and below-ground biota through convergent evolution and divergence among fungal decomposers.
Journal ArticleDOI

Role of fungal peroxidases in biological ligninolysis

TL;DR: Progress in the dissolution and NMR spectroscopy of plant cell walls may allow new inferences about the nature of the oxidants involved, and increasing knowledge about the genomes of ligninolytic fungi may help decide whether any of the peroxidases has an essential role.
