This genome was sequenced as a part of the large-scale multi-genome JGI CSP Saprotrophic Agaricomycotina Project (SAP), which focuses on the diversity and evolution of decay mechanisms, organismal phylogenetic relationships, and developmental evolution. A large collaborative effort led by PI of this project, David Hibbett (Clark University) aims for master publication(s) of the SAP data analysis. Researchers who wish to publish analyses using data from unpublished SAP genomes are respectfully required to contact the PI and JGI to avoid potential conflicts on data use and coordinate other publications with the SAP master paper(s).

Trametes versicolor (L.) Lloyd is a widely distributed Basidiomycetes species, commonly collected on standing dead or fallen hardwood trees. Along with other species Trametes versicolor is a prime wood decomposer, causing strong white rot in the colonized wood. The white rot type biochemistry of T. versicolor along with its wide distribution makes it a good candidate for studies of the complicated ligninocellulolytic system. Several studies have demonstrated the secretion of different types of wood degrading enzymes such as lignin peroxidases, manganese peroxidases and laccases in liquid and solid fermentation cultures of the species. T. versicolor has also been used successfully in several ex situ and in situ bioremediation studies for the biodegradation of recalcitrant organic pollutants. The sequencing of the genome of T. versicolor will shed more light into the evolution of wood degradation mechanisms of the Polyporoid clade and will provide us with a good broad comparison with the genomes of other important wood-rotting species such as Phanerochaete chrysosporium, Postia placenta and Serpula lacrymans. Furthermore, it will provide the tools for broader studies of the wood degradation chemistry and the related bioremediation processes.
