DGGE profiles of the bacterial community in the rhizosphere. Bands indicated by numbers 1–7 were excised, re-amplified, and subjected to sequencing. CK2 was only inoculated with R. solani Q1; OF had applications of R. solani Q1 and the organic fertilizer; N was inoculated with R. solani Q1 and N43; and BIO was inoculated with R. solani Q1 and the BIO product.
