“…While the siderophore-mediated disease suppression correlates well with the elevated chemical stability and affinity for iron (K f Х 10 32 ) of pseudobactins (1,5), the possibility exists that secondary iron-binding compounds from the same bacterium, namely, multiple pseudobactin forms (1,40), ferribactins (21,29), and salicylate-based siderophores (31,43), may contribute to scavenge the limited iron pool in the rhizosphere.…”

“…Given the amino acid composition of the molecule, this mass is in total accordance with the predicted value calculated for a pyoverdin that would contain a cyclized peptide chain and a succinamide residue. In addition, the detection of the RDA fragment ion of m/z 819 (loss of 302 mass units) in the FAB analyses is diagnostic of a pyoverdin containing a succinamide residue (1,11,16,22). Finally, the spectral characteristics of the unchelated molecule, and the color and spectral characteristics of the Fe(III)-chelated molecule near pH 3.0 (Fig.…”

“…tomato LMG 5093 with a Finnigan MAT TSQ 700 mass spectrometer, using thioglycerol as a matrix, in order to detect a fragment ion resulting from the RDA decomposition of the pyoverdin chromophore (29,41). This RDA fragment results from the loss of the quinoline part of the chromophore, together with the acid side chain; it is diagnostic of the pyoverdin chromophore and of its acid side chain (1,11,16,22,29,41).…”
