Additional file 1: of A reservoir of ‘historical’ antibiotic resistance genes in remote pristine Antarctic soils

Table S1. Environmental factors of the 17 sampled sites. Table S2. The selected ARGs chosen from noradab, including the names, gene and ARG description, and ARG families. Figure S1. The number of unique ARGs and number of unique AR hosts per site. Linear model indicated in red and lowess in blue (Pearson’s correlation r = 0.89, P = 1.62e-06). Figure S2. ARG host frequencies across sampled sites. The number of different ARG hosts is indicated in green with the number of unique ARG hosts displayed in red, axis on the left. The black line represents the relative abundance, axis on the right. Figure S3. ARG redundancy analysis. The only environmental factor to display a significant impact was percentage N (P =0.024).
