Financement | Sequencing was supported by funds through United States Department of Agriculture—National Institute of Food and Agriculture Hatch project CA-R-PPA-5062-H. Data analyses were performed on the High-Performance Computing Cluster at the University of California-Riverside in the Institute of Integrative Genome Biology supported by NSF DBI-1429826 and NIH S10-OD016290. Additional support was given through a Royal Thai government fellowship. |

Méthodes d'échantillonnage
Rock samples were excised aseptically, transported, and stored at −20 °C at the Tuscia University (Viterbo, Italy) until processing.
Etendue de l'étude | Sandstone rock samples were collected in triplicate in Victoria Land (Continental Antarctica), along a latitudinal transect from 74°10′10.5′′ S 162°25′38.0′′ E (Timber Peak, Northern Victoria Land) to 77°54′43.6′′ S 161°34′39.3′′ E (Finger Mt., Southern Victoria Land) ranging from 834 m a.s.l. (Battleship Promontory, Southern Victoria Land) to 3100 m a.s.l. (Mt. New Zealand, Northern Victoria Land). In addition, rocks with different sun exposures were collected from four visited sites (Battleship Promontory, Siegfried Peak, Finger Mt. and University Valley). All sites were visited during the XXXII Italian Antarctic Expedition (2015–2016). |

Description des étapes de la méthode:
- Rocks were crushed using a Grinder MM 400 RETSCH (Verder Scientific, Bologna, Italy) in sterile conditions to avoid contamination.
- Metagenomic DNA was extracted from 0.3 g of rocks using MOBIO Power Soil DNA Extraction kit (MOBIO Laboratories, Carlsbad, CA, USA), according to the manufacturer’s instructions. ITS1F (CTTGGTCATTTAGAGGAAGTAA) and ITS2 (GCTGCGTTCTTCATCGATGC) primers were used to amplify the internal transcribed spacer 1 region (ITS1). PCR reactions were performed in a total volume of 25 μL, containing 1 μL of each primer, 12.5 μL of Taq DNA Polymerase (Thermo Fischer Scientific Inc., Waltham, MA, USA), 9.5 μL of nuclease-free water (Sigma-Aldrich, St. Louis, MO, USA) and 5 ng of DNA, following Coleine et al. PCR conditions were initial denaturation at 93 °C for 3 min, 35 cycles of denaturation at 95 °C for 45 s, annealing at 50 °C for 1 min, extension at 72°C for 90 s, followed by a final extension at 72 °C for 10 min in an automated thermal cycler (BioRad, Hercules, CA, USA). Amplicons, purified with Qiagen PCR CleanUp kit (Macherey-Nagel, Hoerdt, France) and quantified using the Qubit dsDNA HS Assay Kit (Life Technologies, Carlsbad, CA, USA), were tagged with unique barcodes to enable identification of each sample, and then pooled for run sequencing.
- Sequencing (paired-end reads, 2 × 300 bp) of the pooled libraries was performed on a single Illumina MiSeq flowcell at the Institute for Integrative Genome Biology, University of California, Riverside.
