This genome was sequenced as part of the 1000 Fungal Genomes Project - Deep Sequencing of Ecologically-relevant Dikarya. Within the framework of this project, we are sequencing keystone lineages of saprophytic, mycorrhizal, and endophytic fungi that are of special ecological importance. Dozens of sequenced species were harvested from Long Term Observatories to serve as the foundation for a reference database for metagenomics of fungi and for a comprehensive survey of the soil fungal metatranscriptome.

In Brazil, the Pantanal and Cerrado biomes are known for their distinctive climatic conditions, which have fostered rich biodiversity. For instance, the Pantanal experiences seasonal flooding, with nearly 80% of the region submerged temporarily. Conversely, the neighboring Cerrado biome faces extended periods of drought, often followed by wildfires that profoundly influence local ecology. Despite their unique characteristics, both biomes have seen a worrying decline in biodiversity in recent decades, largely due to human activities. Within these Brazilian biomes, two medicinal plants, Vochysia divergens from the Pantanal and Stryphonodendron adstringens from the Cerrado, have gained attention for their potential as sources of bioactive chemical compounds. These plants host a diverse array of endophytic fungi capable of producing compounds with demonstrated efficacy against clinical and agricultural pathogens. Consequently, research aimed at gaining a deeper understanding of the bioactive molecules generated by organisms in these biomes will contribute significantly to the valorization of their native biodiversity.
