Genomics of Pseudomonas fluorescens Pf-5

Pseudomonas spp. are ubiquitous inhabitants of soil, water, and plant surfaces, where they represent an important component of microbial assemblages. Members of the species P. fluorescens typically exist as saprophytes or in a commensal relationship with plant or animal hosts. These bacteria are known for their capacity to utilize a striking variety of organic compounds as energy sources and to produce a wide variety of metabolites. Certain plant-associated strains produce phytohormones or metabolites that alter plant hormone levels, and these influence the growth and development of their plant associates. Other strains produce proteins that alter the plant's capacity to avoid frost injury.
