Figure 3. Identification of toxin factor pyoverdine from P. taiwanensis.

Figure 3

(a) Time course of P. taiwanensis cultured for MALDI-IMS to detect m/z 1044 signal after incubation on the iron-limited agar plates for 4, 8, 12, 16, 20, and 24 hours. Scale bar, 10 mm. (b) Structure of pyoverdine and characteristic ions in the ESI-Orbitrap. (c) Comparison of the pyoverdine loci of P. taiwanensis and P. aeroginsa POA1. Genes in the pyoverdine loci of P. taiwanensis were annotated based on the sequences in the Pseudomonas genome database. The genes are classified into colors according to their functions. The arrangement of genes of the pyoverdine loci in P. aeroginsa POA1 according to Ravel and Cornelis43 was confirmed by the Pseudomonas Genome database. The orthologous genes in P. taiwanensis were assigned a number and are shown in Supplemental Table S2.
