Response of Bacterial Community Structure in the Bulk Soil and Rice Straw Residues under Different Crop Rotation Systems

Figure 1

Bacterial 16S rRNA gene Denaturing Gradient Gel Electrophoresis (DGGE) profiles obtained from bulk soils in the different microcosm setups at 0 and after 30 days of (a) incubation, (b) corresponding UPGMA, and (c) PCA results. SR—rice soil; SB—baby corn soil; SR-AN, SR-AE, SB-AN, and SB-AN are treatments with: rice soil under anaerobic conditions, rice soil under aerobic conditions, baby corn soil under anaerobic conditions, and baby corn soil under aerobic conditions, respectively. In the PCA and UPGMA plots, the symbols used to correspond with particular treatments as follows: (solid triangle) SR-AN; (solid diamond) SR-AE; (solid circle) SB-AN; (solid square) SB-AE; (open triangle) soil SR at day 0; (open square) soil SB at day 0.
