This genome was sequenced as part of the 1000 Fungal Genomes Project - Deep Sequencing of Ecologically-relevant Dikarya, and more specifically as part of the Endophyte Genome Sequencing project, which seeks to sequence members of diverse lineages of endophytic species found in Arabidopsis, Populus and other plants to examine the functional diversity of fungi with a shared evolutionary history.

The Auriculariales (Basidiomycete phylum) are an order of fungi in the class Agaricomycetes. Most of the species within the Auriculariales produce gelatinous basidiocarps (fruit bodies) on dead wood, and are often referred to as "jelly fungi".  More than 200 species that belong to 6 families have been described, all believed to be saprophytic. The taxonomic assignment of the sequenced Oliveonia pauxilla MPI-PUGE-AT-0066 isolate is uncertain and its placement in the order Auriculariales needs to be clarified. The fungus has been isolated from healthy Arabidopsis thaliana plants grown in natural soil after surface sterilization of plant roots. The sequencing of this fungal isolate is part of a larger project aiming at sequencing the genomes of numerous phylogenetically diverse root-associated fungi from Arabidopsis, Populus, and other plant hosts for further comparative genome analysis. Unravelling the genomic signatures reflecting the adaptation of these microbes to the host cell environment represent a promising way to better understand how the endophytic lifestyle evolved in phylogenetically unrelated fungal species. Comparative genome analysis between different plant hosts, and between saprotrophic, mycorrhizal, and pathogenic fungi will provide new insights into the specific adaptations but also the conserved signatures associated with these different lifestyles.
