Pyoverdine-deficient mutant Pseudomonas umsongensis CR14ΔpvdA enhances cadmium immobilization by regulating genes and metabolites related to cell wall/membrane biosynthesis and transcription factors.

Abstract excerpt

Cadmium (Cd) pollution poses a significant global environmental threat. This study elucidates the molecular mechanisms by which the pyoverdine-producing pvdA gene deletion mutant Pseudomonas umsongensis CR14ΔpvdA (ΔpvdAM) enhances Cd immobilization in a Cd-containing solution. Transcriptomic analysis revealed that, compared to the wild-type CR14, the ΔpvdAM significantly upregulated genes related to...
