Interpretive Summary: The complete genome of the biological control organism Pseudomonas fluorescens Pf-5 was sequenced. Pf-5 is a well-known biological control agent that lives on seeds and roots, produces numerous antibiotics that are toxic to soilborne plant pathogens, and suppresses soilborne plant diseases. The genome of Pf-5 contains 10 genetic regions specifying for the production of secondary metabolites, some of which are already known to suppress the growth of soilborne plant pathogens. Other factors contributing to biological control of plant disease include a large number of genes allowing Pf-5 to use many different substrates for its growth. These genes confer a broad capacity for utilization of sugars and amino acids that are commonly secreted by roots and seeds, and undoubtedly contribute to the growth of Pf-5 on root and seed surfaces. Genomic sequencing of Pf-5 was done at The Institute of Genomics Research, under the direction of Dr. Ian Paulsen.
