This genome was sequenced as part of the JGI CSP “Survey of the lignocellulolytic capabilities over the order Polyporales” project. Within Agaricomycotina, the order Polyporales is the major group of wood decayers in temperate and tropical forests. As such, Polyporales have a pivotal role in the global carbon cycle. Polyporales include a large number of white-rot filamentous fungi able to totally degrade lignin from wood through the production of extracellular lignin-degrading enzymes including laccases, lignin peroxidases and manganese peroxidases. Lignocellulose is a high potential renewable resource for the production of biofuels and chemicals, including high-value chemicals, from biomass. As a consequence, white-rot filamentous fungi have a high potential for biotechnological processes, particularly for lignocellulosic feedstock biorefinery applications.

Abortiporus biennis (Bull.: Fr.) Singer, is a white-rot fungus from the taxonomic family of Podoscyphaceae (Justo et al., Fungal Biology, 2017) that grows on buried wood.

A. biennis has been particularly studied for its ability to produce laccases or for bioremediation of recalcitrant pesticides, heavy metals and effluent decoulorization. The genome sequencing for A. biennis will allow exploration for novel biocatalysts and deepen our understanding on the functional diversity among Polyporales.
