Title: | Pre-Cambrian roots of novel Antarctic cryptoendolithic bacterial lineages | Authors: | Albanese, Davide Coleine, Claudia Rota-Stabelli, Omar Onofri, Silvano Tringe, Susannah G Stajich, Jason E Selbmann, Laura Donati, Claudio |
Journal: | MICROBIOME | Issue Date: | 2021 | Abstract: | Cryptoendolithic communities are microbial ecosystems dwelling inside porous rocks that are able to persist at the edge of the biological potential for life in the ice-free areas of the Antarctic desert. These regions include the McMurdo Dry Valleys, often accounted as the closest terrestrial counterpart of the Martian environment and thought to be devoid of life until the discovery of these cryptic life-forms. Despite their interest as a model for the early colonization by living organisms of terrestrial ecosystems and for adaptation to extreme conditions of stress, little is known about the evolution, diversity, and genetic makeup of bacterial species that reside in these environments. Using the Illumina Novaseq platform, we generated the first metagenomes from rocks collected in Continental Antarctica over a distance of about 350 km along an altitudinal transect from 834 up to 3100 m above sea level (a.s.l.). |
