概要

Pseudomonas putida KF715 exhibits unique properties in both catabolic activity and genome plasticity. Our previous studies revealed that the DNA region containing biphenyl and salycilate metabolism gene clusters (termed the bph-sal element) was frequently deleted and transferred by conjugation to closely related P. putida strains. In this study, we first determined the complete nucleotide sequence of the KF715 genome. Next, to determine the underlying cause of genome plasticity in KF715, we compared the KF715 genome with the genomes of one KF715 defective mutant, two transconjugants, and several P. putida strains available from public databases. The gapless KF715 genome sequence revealed five replicons: one circular chromosome, and four plasmids. Southern blot analysis indicated that most of the KF715 cell population carries the bph-sal element on the chromosome whereas a small number carry it on a huge plasmid, pKF715A. Moreover, the bph-sal element is present stably on the plasmid and did not integrate into the chromosome of its transconjugants. Comparative genome analysis and experiments showed that a number of diverse putative genetic elements are present in KF715 and are likely involved in genome rearrangement. These data provide insights into the genetic plasticity and adaptability of microorganisms for survival in various ecological niches.
