In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya” project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems. In addition, comparative genome analysis with saprotrophic, mycorrhizal and pathogenic fungi will provide new insights into the specific and conserved adaptations associated with each fungal lifestyle.

The Ochre Brittlegill (Russula ochroleuca Pers.)

Russula ochroleuca is a very common taxon in acidic soils of coniferous forests as well as in acidic hardwood forests of beech and oak. It was found to be very common in acidic soils with high N contant such as in the coniferous stands of lowland plantations of Central Europe (Žifčáková et al. 2016) and coniferous mountain spruce forests affected by acidic deposition that are N-saturated (Kohout et al. 2018). In both cases, Russula ochroleuca was the most abundant ectomycorrhizal fungus. Furthermore, with lower frequency, the fungus also occurs in N-rich acidic beech and oak sites of central Europe (Bahnmann et al. 2018). The fungus is strictly acidophilic as demonstrated by its disappearance after liming of the forest soils (Rineau et al. 2010). The fact that Russula ochroleuca prefers N-rich soils makes it a suitable model of the functioning of the tree-fungus symbiosis in the system where the trees are not dependent on mycorrhizal N-supply. The fungus forms fruitbodies from August till November. The sporocarps for this genome were collected by Petr Baldrian et al. on August 15, 2013 in a mountainous coniferous forest in the Bohemian Forest, Central Europe with dominant Picea abies.

The 1KFG project is a large collaborative effort aiming for master publication(s). Please do contact the PI associated with unpublished 1KFG genomes for permission prior to the use of any data in publications.
