Comparison of DGGE patterns for bulk and rhizosphere soil communities in a grassland field. Samples were taken in two different plots at the same location. (A) DGGE patterns for bulk soil from plot 47 (lane 1), rhizosphere soil from plot 47 (lane 2), bulk soil from plot 31 (lane 3), and rhizosphere soil from plot 31 (lane 4). Lane M contained Burkholderia markers (from top to bottom, B. andropogonis LMG6872, B. multivorans LMG13010, B. cepacia ATCC 25416, and B. cepacia LMG18941). (B) Clustering by the unweighted pair group method with mathematical averages, showing the levels of similarity of the microbial communities obtained by using the Burkholderia-specific PCR-DGGE system.
