Figure 1. Quantification of nifH genes and transcripts in bulk soil and rhizosphere of Poaceae genotypes by real-time PCR and RT-PCR, respectively.

Figure 1

Gene copy numbers are shown in (A,C,E) and transcript numbers in (B,D,F). Statistical analyses were performed independently at 21 days in cropped soil, at 21 days in meadow soil and at 42 days in cropped soil, using ANOVA and Fisher LSD tests (P < 0.05; results shown with letters a to (D). For FV4, W85, tomato and bulk soil, two-way ANOVA and Fisher LSD tests (P < 0.05) were also performed to compare treatments according to past soil management or sampling time, and differences with the same genotype at 21 days in cropped soil are indicated by symbols *and #respectively.
