population structure and diversity of phenazine-1-carboxylic acid producing fluorescent pseudomonas spp. from dryland cereal fields of central washington state (usa). | certain strains of the rhizosphere bacterium pseudomonas fluorescens contain the phenazine biosynthesis operon (phzabcdefg) and produce redox-active phenazine antibiotics that suppress a wide variety of soilborne plant pathogens. in 2007 and 2008, we isolated 412 phenazine-producing (phz(+)) fluorescent pseudomonas strains from roots of dryland wheat and barley grown in the low-precipitation region (<350 mm annual precipitation) of central washington state. based on results of box-pcr genomic fi ... | 2012 | 22383119 |
