Figure 5. DGGE fingerprint generated from the reamplified PCR products from rhizosphere soil sample of C. polygonoides from sites 2 (a) and 3 (b), with there corresponding controls, showing the effect of change in template concentration at PCR level. The template concentrations of 100, 500 and 1000 ng are shown which have been generated from rhizosphere soil samples (lane 1-3; a and b) and their corresponding bulk soil samples (lane 4-6; a and b).
