Figure 5. QsdB-mediated quorum-quenching in P. carotovorum.

Figure 5

In A, relative abundance of NAHLs (OC8HSL as the main QS-signal) in wild-type P. carotovorum CFBP6276 (Pca6276), and P.carotovorum harboring the empty vector pME6000 and the pMTXhoI plasmid expressing QsdB. In B, symptoms on potato tubers (n = 14) inoculated with Pca6276, Pca6276 (pME6000), Pca6276 (pMTXhoI) or NaCl 0.8% as a negative control were classified according to their importance (see material and methods) and compared using Kruskal-Wallis test (P<0.05). Different letters indicate statistical differences between the compared plant pathogens.
