↵a C0, Cosnino interspace; C1, Cosnino rhizosphere; S0, Sunset Crater interspace; S1, Sunset Crater rhizosphere.

↵b Phylotype richness,

*S*, was calculated as the total number of distinct TRF sizes (between 94 and 827 bp) in a profile.↵c Shannon-Weiner diversity index (19) was calculated as follows: H = −Σ(

*p*)(log_{i}_{2}*p*), where_{i}*p*is the proportion of an individual peak height relative to the sum of all peak heights.↵d Boldface type indicates the lowest value in each series.
