Dissociation and interaction of individual components of a degradative plasmid aggregate in Pseudomonas.
The transfer of the OCT plasmid from Pseudomonas oleovorans to Pseudomonas putida strain PpGl results in the acquisition of three independent replicons: OCT, factor K, and the MER plasmid. OCT is a nontransmissible plasmid harboring genes that code for the enzymes responsible for the degradation of n-octane. Factor K is a transfer plasmid capable of mobilizing OCT as well as chromosomal genes b...
متن کاملEffects of carbazole-degradative plasmid pCAR1 on biofilm morphology in Pseudomonas putida KT2440.
Bacteria typically form biofilms under natural conditions. To elucidate the effect of the carriage of carbazole-degradative plasmid pCAR1 on biofilm formation by host bacteria, we compared the biofilm morphology, using confocal laser scanning microscopy, of three pCAR1-free and pCAR1-carrying Pseudomonas hosts: P. putida KT2440, P. aeruginosa PAO1 and P. fluorescens Pf0-1. Although pCAR1 did no...
متن کاملpA506, a conjugative plasmid of the plant epiphyte Pseudomonas fluorescens A506.
Conjugative plasmids are known to facilitate the acquisition and dispersal of genes contributing to the fitness of Pseudomonas spp. Here, we report the characterization of pA506, the 57-kb conjugative plasmid of Pseudomonas fluorescens A506, a plant epiphyte used in the United States for the biological control of fire blight disease of pear and apple. Twenty-nine of the 67 open reading frames (...
متن کاملConjugative plasmid transfer in gram-positive bacteria.
Conjugative transfer of bacterial plasmids is the most efficient way of horizontal gene spread, and it is therefore considered one of the major reasons for the increase in the number of bacteria exhibiting multiple-antibiotic resistance. Thus, conjugation and spread of antibiotic resistance represents a severe problem in antibiotic treatment, especially of immunosuppressed patients and in inten...
متن کاملPlasmid capture by the Bacillus thuringiensis conjugative plasmid pXO16.
Conjugation, mobilization, and retromobilization are three related mechanisms of horizontal gene transfer in bacteria. They have been extensively studied in gram-negative species, where retromobilization, the capture of DNA from a recipient by a donor cell, was shown to result from two successive steps: the transfer of the conjugative plasmid from the donor to the recipient followed by the retr...
