FIGURE 1

Copy numbers of bacterial (A) and archaeal (B) 16S rRNA genes in rhizosphere (open bars) and bulk soil (filled bars) at different sampling times (days 34, 52, 62, 90); the average of the four sampling times is also shown. Asterisks indicate when the abundance in rhizosphere and bulk soil was different (ANOVA, P < 0.05). Error bars correspond to standard errors of means from replicate soil samples (n = 5).
