Abstract: A locus specifying polyphosphate kinase (ppk) and a nonpredicted antisense RNA (iiv8) in Pseudomonas fluorescens Pf0-1 is required for optimal competitive fitness in LB broth culture and sterile loam soil. The results have shown a new role for polyphosphate in competitive fitness of Pseudomonas fluorescens in laboratory and soil environments.
