Comparison of mean <i>amoA</i> genes concentrations for AOA and AOB assemblages in the olive trees rhizosphere.

aMean copies of amoA gene per gram of soil rhizosphere Significant differences within each assemblage along the different agronomic factors were tested (p< 0.05, different letter a, b or c). Significant differences (p<0.05) in the mean concentrations between AOA and AOB assemblages were marked with an asterisk beside the corresponding class. For Soil Management Systems (SMS) code see Table 1. Comparison of mean amoA genes concentrations for AOA and AOB assemblages in the olive trees rhizosphere.
