Phenazines in plant‐beneficial Pseudomonas spp.: biosynthesis, regulation, function and genomics

Summary Plant‐beneficial phenazine‐producing Pseudomonas spp. are proficient biocontrol agents of soil‐dwelling plant pathogens. Phenazines are redox‐active molecules that display broad‐spectrum antibiotic activity toward many fungal, bacterial and oomycete plant pathogens. Phenazine compounds also...

Summary:Summary Plant‐beneficial phenazine‐producing Pseudomonas spp. are proficient biocontrol agents of soil‐dwelling plant pathogens. Phenazines are redox‐active molecules that display broad‐spectrum antibiotic activity toward many fungal, bacterial and oomycete plant pathogens. Phenazine compounds also play a role in the persistence and survival of Pseudomonas spp. in the rhizosphere. This mini‐review focuses on plant‐beneficial phenazine‐producing Pseudomonas spp. from the P. fluorescens species complex, which includes numerous well‐known phenazine‐producing strains of biocontrol interest. In this review the current knowledge on phenazine biosynthesis and regulation, the role played by phenazines in biocontrol and rhizosphere colonization, as well as exciting new advances in the genomics of plant‐beneficial phenazine‐producing Pseudomonas spp. will be discussed.
