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 Helotiales sp. UNIPAMPA011 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.

Helotiales sp. UNIPAMPA011 , a fungus from Antarctica
Taxa belonging to the order Helotiales were cited in different regions of Antarctica, including psychrotolerant species, associated with the Antarctic soil of King George Island. The order Helotiales (Ascomycota), commonly found in bryophytes from Antarctica, can also be found frequently on the roots of Antarctic Hairgrass (Deschampsia antarctica). Some fungal taxa belonging to the order Helotiales, isolated from Antarctica, are characterized by their competitive capacity, gene expression, stress tolerance and enzyme production. The isolate UNIPAMPA011 of Helotiales sp. has been isolated from healthy leaves of the Antarctic Hairgrass, one of two flowering plants native to Antarctica and the southernmost flowering plant.
