Polymorphism of the polyketide synthase gene phID in biocontrol fluorescent pseudomonads producing 2,4-diacetylphloroglucinol and comparison of PhID with plant polyketide synthases.

Many biocontrol fluorescent pseudomonads can protect plants from soilborne fungal pathogens through production of the antifungal secondary metabolite 2,4-diacetylphloroglucinol (Phl). One of the phl biosynthetic genes, phlD, encodes a polyketide synthase similar to plant chalcone synthases. Here, re... View More
