Quorum-sensing and siderophore biosynthesis in Pseudomonas aeruginosa: lasR/lasI mutants exhibit reduced pyoverdine biosynthesis.

FEMS microbiology letters - 15 Sept 1998

Stintzi A, Evans K, Meyer J M, Poole K

Abstract excerpt

Cell density-dependent gene expression in Pseudomonas aeruginosa is controlled, in part, by the quorum-sensing regulator LasR. lasR null mutants exhibited a reproducible 2-fold decrease in production of the catecholate-hydroxamate siderophore pyoverdine during grown under iron-limiting conditions. Similarly, lasI mutants defective in the biosynthesis of the autoinducer PAI-1 also exhibited a 2-fold decrease in...
