Principal component analysis of Bacillus (a) and Pseudomonas (b) spp. communities in cucumber rhizosphere soils based on PCR-DGGE analysis. W represents cucumber rhizosphere soils treated with water. 0.02, 0.05, 0.1 and 0.2 represent cucumber rhizosphere soils treated with vanillic acid at 0.02, 0.05, 0.1, 0.2 μmol g−1 soil concentrations, respectively.
