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.

The sequencing of Cadophora sp. is part of a study aiming at sequencing the genomes of numerous phylogenetically diverse endophytic fungi 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.

Cadophora sp., a fungus from Antarctica
The ecosystems of Antarctica are characterized by extreme temperatures, with microorganisms being the most adapted to proliferate in the substrates of this continent. Microorganisms that develop in Antarctic ecosystems are capable of producing cold-adapted enzymes. The genus Cadophora is a group of ascomycetes belonging to the order Helotiales. Species belonging to the genus Cadophora are frequent, common and widespread members of DSE communities. This genus is also frequently isolated from Antarctic soils, suggesting that they are important organisms in the dynamics and nutrient cycling of polar regions.
The order Helotiales (Ascomycota), commonly found in bryophytes from Antarctica, can also be found frequently on the roots and leaves of Antarctic Hairgrass (Deschampsia antarctica). The isolate UNIPAMPA014 of Cadophora sp. was isolated from healthy leaves of the Antarctic Hairgrass, one of two flowering plants native to Antarctica and the southernmost flowering plant.
