Métodos de Muestreo

Soil was collected under populations of Colobanthus quitensis (Kunth) Bartl. and Deschampsia antarctica Desv., the only two native vascular plant species that occur in Antarctica. On each island, 50 mL sterile centrifuge tubes (Corning Inc, Corning, NY, USA) were used to collect samples by hammering them directly into the vertical walls of three soil pits at three depths (2, 4 and 8 cm). Soil was stored at −80 °C within 5 h of collection and was later freeze‐dried to preserve fungal nucleotides.

Área de Estudio Between October and November 2011, soil samples were collected from Bird Island (54.0089° S, 38.0662° W), Signy Island (60.7107° S, 45.5849° W) and Léonie Island (67.5984° S, 68.3561° W) in the sub‐Antarctic, low maritime and high maritime Antarctic respectively.

Descripción de la metodología paso a paso:

  1. Total DNA was extracted from five individual 50 mg soil samples, using the RNA PowerSoil Total RNA Isolation and DNA Elution Accessory kits (MoBio Laboratories, Carlsbad, CA, USA). The extracted DNA was amplified in triplicate PCR reactions using ITS1F and ITS4 primers. The ITS4 primer was modified with the 454 A adaptor and a 10-bp barcode specific to each sample, allowing the identification of different samples once pooled, and the ITS1F primer was modified with the 454 B adaptor. This primer design allowed reverse sequencing across the ITS2 region. Triplicate PCR reactions were performed using Phusion HF 2X Master Mix (New England Biolabs, Beverly, MA, USA) using the following amounts per 50 μl reaction: 19 μl H20; 25 μl 2X HF mix; 2.5 μl of each primer; 1 μl template, and the following PCR cycle: initial denaturation of 98°C for 45 s, then for 33 cycles: denaturation: 98°C for 10 s, annealing: 53°C for 30 s, extension: 72°C for 30 s, final extension: 72°C for 7 min. The triplicate PCR products were pooled and subsequently purified using AMPure XP bead purification (Beckman Coulter, Inc, Brea, CA, USA) and quantified using Qubit dsDNA HS Assay (Life Technologies, Carlsbad, CA, USA) before normalization to equal concentrations. The purified and normalized PCR products were run on one plate on the 454 Roche Titanium FLX platform at the Liverpool Centre for Genomic Research.
