Siderophore-mediated cell signalling in Pseudomonas aeruginosa: divergent pathways regulate virulence factor production and siderophore receptor synthesis.
-
FpvR negatively regulates FpvI, which is required for FpvA synthesis; ferri-pyoverdine increases FpvI activity.
"FpvR negatively regulates the activity of a second ECF sigma factor, FpvI, which is required for the synthesis of FpvA"
Pyoverdine-mediated regulation of FpvA synthesis in Pseudomonas aeruginosa: involvement of a probable extracytoplasmic-function sigma factor, FpvI.
-
Deletion of fpvI abolishes pyoverdine-dependent fpvA expression; cloned fpvI stimulates it.
"Deletion of this gene, dubbed fpvI, compromised pyoverdine-dependent FpvA ferric pyoverdine receptor production and fpvA gene expression, while the cloned gene stimulated fpvA expression"

Review grouping the P. aeruginosa ECF sigma factors by function.
"the iron starvation σ (PvdS, FpvI, HasI, FecI, FecI2 and others), the cell wall stress ECFσ AlgU, SigX and SbrI, and the unorthodox σVreI involved in the expression of virulence"
