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 Arthrinium esporlense 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.
Arthrinium esporlense, a fungus
from Antarctica
Arthrinium species have a worldwide distribution and have
been reported from different habitats on variety of hosts, these
species can be pathogens, saprobes, as well as endophytes. Many
species of Arthrinium were found in temperate, cold or
alpine regions, mainly growing on Cyperaceae, Juncaceae and Poaceae
hosts. The isolate UNIPAMPA010 of Arthrinium esporlense is
an ascomycete (Sordariomycetes, Xylariales), has been isolated from
healthy leaves of the Antarctic Hairgrass (Deschampsia
antarctica), one of two flowering plants native to Antarctica
and the southernmost flowering plant. This genus can also be found
in Antarctic lakes.
