Construction of a broad host range cosmid cloning vector and its use in the genetic analysis of Rhizobium mutants.
We have constructed a cosmid derivative of the low copy-number broad host-range cloning vector pRK290 (Ditta et al., 1980) by inserting a 1.6-kb Bg/II fragment containing lambda cos into the unique Bg/II site in pRK290. The new vector, pLAFR1, is 21.6 kb long, confers tetracycline resistance, contains a unique EcoRI site, and can be mobilized into and stably replicates within many Gram-negative...
متن کاملBroad-host-range vector system for synthetic biology and biotechnology in cyanobacteria
Inspired by the developments of synthetic biology and the need for improved genetic tools to exploit cyanobacteria for the production of renewable bioproducts, we developed a versatile platform for the construction of broad-host-range vector systems. This platform includes the following features: (i) an efficient assembly strategy in which modules released from 3 to 4 donor plasmids or produced...
متن کاملBroad-Host-Range Plasmid by Electroporation
Methylotrophic bacteria able to grow on one-carbon compounds, such as methanol and monomethylamine, as sole carbon sources have received considerable attention because of their potential commercial applications, including the production of single-cell protein, amino acids, pyrroloquinoline quinone, and poly-3-hydroxybutyrate. The utility of methylotrophs should be increased by the use of recomb...
متن کاملAdaptive plasmid evolution results in host-range expansion of a broad-host-range plasmid.
Little is known about the range of hosts in which broad-host-range (BHR) plasmids can persist in the absence of selection for plasmid-encoded traits, and whether this "long-term host range" can evolve over time. Previously, the BHR multidrug resistance plasmid pB10 was shown to be highly unstable in Stenotrophomonas maltophilia P21 and Pseudomonas putida H2. To investigate whether this plasmid ...
متن کاملDirect selection of IS903 transposon insertions by use of a broad-host-range vector: isolation of catalase-deficient mutants of Actinobacillus actinomycetemcomitans.
Transposon mutagenesis in bacteria generally requires efficient delivery of a transposon suicide vector to allow the selection of relatively infrequent transposition events. We have developed an IS903-based transposon mutagenesis system for diverse gram-negative bacteria that is not limited by transfer efficiency. The transposon, IS903phikan, carries a cryptic kan gene, which can be expressed o...
