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.

Trametes polyzona (Pers.) Justo, previously named Coriolopsis polyzona, was first described as Basionym Polyporus polyzonus (Justo & Hibbett, Taxon, 2011). It is a coriaceous and corky pantropical polypore. The pileus is reniform to flabelliform. Specimens are broadly attached on dead harwood of any sort. The pilear surface is yellowish to ocraceous and tomentous to hairy in numerous concentric zones. Pores surface is white to cream. This tropical white-rot fungus has been identified as a producer of laccase, manganese peroxidase and lignin peroxidase. Several potential biotechnological applications have been investigated using this fungus, such as the decolorization of olive oil mill wastewater and synthetic dyes or the elimination of endocrine disrupting chemicals.

The genome sequencing for T. polyzona will allow the exploration of novel biocatalysts and deepen our understanding of the functional diversity among Polyporales, i.e. enzymatic capabilities linked to plant cell wall modifications.
