A Multiomic Approach to Understand How Pleurotus eryngii Transforms Non-Woody Lignocellulosic Material.

ABSTRACT: Pleurotus eryngii is a grassland-inhabiting fungus of biotechnological interest due to its ability to colonize non-woody lignocellulosic material. Genomic, transcriptomic, exoproteomic, and metabolomic analyses were combined to explain the enzymatic aspects underlaying wheat-straw transformation. Up-regulated and constitutive glycoside-hydrolases, polysaccharide-lyases, and carbohydrate-esterases active on polysaccharides, laccases active on lignin, and a surprisingly high amount of constitutive/inducible aryl-alcohol oxidases (AAOs) constituted the suite of extracellular enzymes at early fungal growth. Higher enzyme diversity and abundance characterized the longer-term growth, with an array of oxidoreductases involved in depolymerization of both cellulose and lignin, which were oft
