    Notes: Summary A methyl methane sulfonate sensitive mutant of P. putida strain PpG1 is also extremely sensitive to UV-rays, compared to parent wild type cells. This mutant behaves typically as recombination less (recA) mutants of Escherichia coli and Pseudomonas aeruginosa, since as a recipient, it exhibits extremely low frequency of recombination following conjugational, transductional, and transformational gene transfer. Sex factor plasmids such as K-XYL or TOL can mobilize chromosomal genes equally well both from recA + and recA801 donor cells, suggesting that host recombination functions are not necessary for mobilization of chromosomal genes by such plasmids.

    Notes: Summary Transfer of the non-conjugative xylene-degradative plasmid, XYL, mediated by the sex factor plasmid K, from Pseudomonas Pxy to P. putida strain PpGl results in the formation of XYL+ K+ PpGl exconjugants. Isolation of plasmid DNA from exconjugants, transductants and transformants and their electron microscopic characterization suggest that they occur predominantly as plasmid co-integrates with a varying number of copies of XYL on K. Free forms of XYL and K also occur at low frequency. Growth of cells harboring such recombinant XYL-K plasmids with xylene (or intermediates such as meta-toluate) ensures the retention of K. A membrane filter mating technique has been developed, using PpGl cells harboring XYL-K plasmids as donors and K- auxotrophs as recipients. The time of entry of a number of individual chromosomal markers has been precisely determined, and a tentative map of the P. putida chromosome has been constructed.
