The results of two-tailed t tests are reported for the contribution of the secondary T-RFs, indicative of a ribotype from the candidate phylum TM7, to the air-treated (Ga2) and H2-treated (Gh2) soil cores from the second GES soil experiment. The abbreviations used are the same as those in Table 1 and Fig. 3.
