Distribution of 2,4-Diacetylphloroglucinol Biosynthetic Genes among the Pseudomonas spp. Reveals Unexpected Polyphyletism.

ABSTRACT: Fluorescent pseudomonads protecting plant roots from phytopathogens by producing 2,4-diacetylphloroglucinol (DAPG) are considered to form a monophyletic lineage comprised of DAPG⁺Pseudomonas strains in the "P. corrugata" and "P. protegens" subgroups of the "Pseudomonas fluorescens" group. However, DAPG production ability has not been investigated for many species of these two subgroups, and whether or not the DAPG⁺Pseudomonas are truly monophyletic remained to be verified. Thus, the distribution of the DAPG biosynthetic operon (phlACBD genes) in the Pseudomonas spp. was investigated in sequenced genomes and type strains. Results showed that the DAPG⁺Pseudomonas include species of the "P. fluorescens
