Whole-genome sequencing of the endemic Antarctic fungus Antarctomyces pellizariae reveals an ice-binding protein, a scarce set of secondary metabolites gene clusters and provides insights on Thelebolales phylogeny.

The snow-covered surfaces of Antarctica comprise an extreme environment that favors the development of life forms with adaptations to adverse low-temperature habitats. The ability to survive and such temperatures might involve the production of antifreeze proteins and ice-binding proteins that attenuate the effects of intense cold temperatures. He, we sequenced and reconstructed the nuclear and mitochondrial genomes of the endemic Antarctic fungus Antarctomyces pellizariae UFMGCB 12416. We then have identified a putative ice-binding protein-coding gene, mapped the presence of secondary metabolite gene clusters, and reconstructed the phylogenetic relationships of a A. pellizariae with others Leotiomycetes from the alignment of hundreds of orthologous single-copy proteins. Our results will deepen the understanding of microbial ice-binding proteins and the genomic aspects of psychrophilic fungi.
