Technical Abstract: The vast majority of plant-associated bacteria live in a commensal relationship with plants, utilizing nutrients exuded from plant surfaces and surviving environmental stress by occupying protected sites provided by the plant's architecture. Prominent among the commensal bacteria are the Pseudomonas spp.,a diverse genus known for its ubiquity in natural habitats. The root-inhabiting bacterium. P.fluorescens Pf-5 was selected for genomic sequencing because of its importance as a biological control organism, the spectrum of secondary metabolites that it produces, and its status as model strain for studies of gene regulation. Diverse genes known to contribute to biological control and rhizosphere competence of Pseudomonas spp. are present in the 7.1 MB genome of Pf-5. Implications of genomics for advancing knowledge of biological control and the commensal life style of bacteria will be discussed.
