Thin-layer chromatogram of the AHLs produced by R. grahamii CCGE502 and derivatives. 1) R. grahamii CCGE502 wild type strain; 2) R. grahamii CCGE502aΔtraI; 3) A. tumefaciens GMI9023 (pRgrCCGE502a: GFP); 4) A. tumefaciens GMI9023 (pRgrCCGE502aΔtraI) and 5) A. tumefaciens GMI9023 (negative control). Equal amounts of sample were loaded in each lane, except at lane 3 where the sample was ten-fold concentrated.
