FIG 2 .

16S gene copy number corrected relative abundances of microbial phylogenetic groups summarized at the phylum level across the successional gradient prewetting (D, dry) and postwetting (WE, wetting early time point at 18 h after wetting; WL, wetting late time point at 25.5 h after wetting), based on 16S rRNA gene (a) and 16S rRNA (b). For each bar plot, the stacking order of phyla is fixed and as shown in the legend. A bloom of Firmicutes (red) after wetting is apparent within each subpanel.
