Figure 1.
Normalized signal intensity of gyrB genes derived from different phylogenetic groups in the rhizosphere and bulk soil.
All data are presented as means ± standard errors (n = 3). *p<0.05, and **p<0.01.
Table 1.
Soil carbon and nitrogen content (%) and microbial diversity indices based on 454-pyrosequencing and GeoChip data in the rhizosphere and bulk soils.
Figure 2.
Normalized signal intensity of genes involved in (a) carbon fixation, (b) carbon degradation pathways in the rhizosphere and bulk soil.
All data are presented as means ± standard errors (n = 3). *p<0.05, and **p<0.01.
Figure 3.
Differences in the abundance of N cycling genes in the rhizosphere and bulk soil.
The numbers in brackets indicate the percentage difference of a functional gene signal intensity between rhizosphere and bulk soil samples relative to the normalized signal intensity in the bulk soil sample. The gray-colored genes were not detected by GeoChip 3.0. *p<0.05, and **p<0.01.
Figure 4.
Normalized signal intensity of genes involved in (a) phosphorus utilization, (b) sulfur cycling in the rhizosphere and bulk soil.
All data are presented as means ± standard errors (n = 3). *p<0.05, and **p<0.01.
Figure 5.
Normalized signal intensity of antibiotic resistance genes in the rhizosphere and bulk soil.
All data are presented as means ± standard errors (n = 3). *p<0.05, and **p<0.01.
