چکیده

RSF1010 plasmid DNA was introduced into Pseudomonas putida and P. aeruginosa cells and maintained stably, suggesting the potential usefulness of this plasmid as a vector in Pseudomonas species. The number of copies of RSF1010 was 43 per chromosome equivalent in P. putida cells.

Promoters of the broad host range plasmid RK2: analysis of transcription (initiation) in five species of gram-negative bacteria.

A broad host range cloning vector was constructed, suitable for monitoring promoter activity in diverse Gram-negative bacteria. This vector, derived from plasmid RSF1010, utilized the firefly luciferase gene as the reporter, since the assay for its bioluminescent product is sensitive, and measurements can be made without background from the host. Twelve DNA fragments with promoter activity were...

Ecological and genetic analysis of copper and streptomycin resistance in Pseudomonas syringae pv. syringae.

Strains of Pseudomonas syringae pv. syringae resistant to copper, streptomycin, or both compounds were recovered from symptomless and diseased tissue of four woody hosts in three nurseries in Oklahoma. In strains resistant to copper and streptomycin (Cur Smr), resistance to both compounds was cotransferred with a single plasmid which was either 68, 190, or 220 kilobase pairs (kb). All Cus Smr s...

Use of immunogenic moiety of Pseudomonas aeruginosa exotoxin A as a DNA vaccine in experimentally contaminated mice

Background: DNA immunization is an appropriate method to produce an immunological response. Pseudomonas aeruginosa produces exotoxin A which is highly cytotoxic for eukaryotic cells. Since domains II (translocation domain) and 1b of the toxin have antigenic qualities, so they could be  useful candidates to protect against pseudomonas infections. Objectives: To evaluate if recombinant plasmid co...

Deletion plasmids from transformants of Pseudomonas aeruginosa trp cells with the RSF1010-trp hybrid plasmid and high levels of enzyme activity from the gene on the plasmid.

A RSF1010-trp hybrid plasmid which contained the tryptophan operon of Escherichia coli was introduced into Pseudomonas aeruginosa trp cells by transformation. From the Trp+ transformants several deletion plasmids were obtained, and their physical maps with restriction endonucleases were constructed. P. aeruginosa trp cells with these plasmids showed at first more than 100 times higher levels of...

Novel assay to measure the plasmid mobilizing potential of mixed microbial communities

Mobilizable plasmids lack necessary genes for complete conjugation and are therefore non-self-transmissible. Instead, they rely on the conjugation system of conjugal plasmids to be horizontally transferred to new recipients. While community permissiveness, the fraction of a mixed microbial community that can receive self-transmissible conjugal plasmids, has been studied, the intrinsic ability o...
