Figure 4. DGGE fingerprints of 16S rRNA gene fragments PCR-amplified from TC DNA extracted from soil and rhizosphere samples, and corresponding UPGMA dendrogram.

(A) DGGE profiles of dominant bacterial populations in Haplic Chernozem (HC) soil and in the maize rhizosphere of KWS13, KWS14, KWS15 and MON88017 grown in the same soil type in presence (L+) or absence (L−) of WCR larvae. Independent replicates are labeled 1 to 4. M: Bacterial marker [34]. Arrows indicate WCR larval effects on the rhizosphere bacterial communities.
