The efficiency of conjugal transfer of plasmids from Escherichia coli to the cyanobacterium Anabaena sp. strain PCC 7120 was quantitated as a function of the number of restriction sites for the restriction enzymes carried by the recipient. In addition to the previously recognized isoschizomers of AvaI and AvaII, PCC 7120 was found to possess an isoschizomer of AvaIII. Plasmids modified in E. coli with methylases that protect in vitro against restriction by the three enzymes were transferred… Expand
High efficiency intergeneric conjugal transfer of plasmid DNA from Escherichia coli to methyl DNA-restricting streptomycetes.
TLDR
The conjugation procedure is efficient enough to obtain exconjugants with 'suicide' delivery plasmids and therefore provides a simple route for conducting gene disruptions in methyl DNA-restricting streptomycetes, and possibly other bacteria. Expand
Inability of Some Aeromonas hydrophila Strains to Act as Recipients of Plasmid pRAS1 in Conjugal Transfer Experiments
TLDR
It is found that none of these factors could explain the refractivity of non-receptive A. hydrophila strains to yield transconjugants, and it is speculated that these isolates lack a product necessary to replicate or stabilize plasmid pRAS1, or could contain a product that impedes plasmids establishment.

The EcoKI Type I Restriction-Modification System in Escherichia coli Affects but Is Not an Absolute Barrier for Conjugation
TLDR
It is shown that inactivation of the R.EcoKI restriction enzyme in strain Escherichia coli K-12 strain MG1655 increases the conjugational transfer of plasmid pOLA52, which carriers two EcoKI recognition sites, leading to the conclusion that EcoKI restriction-modification affects the uptake of DNA by conjugation but is not a major barrier to plasmids transfer.

Premethylation of Foreign DNA Improves Integrative Transformation Efficiency in Synechocystis sp. Strain PCC 6803
TLDR
Effective expression of methyltransferase C, which could be achieved by optimizing the 5′ untranslated region, was critical to efficient premethylation of the donor DNA and thus high transformation efficiency in Synechocystis 6803. Expand
Plasmid Conjugation from Proteobacteria as Evidence for the Origin of Xenologous Genes in Cyanobacteria
TLDR
The results suggest the existence of potentially ample channels of gene flow between proteob bacteria and cyanobacteria and point to MPFT-based interphylum conjugation as a potential mechanism to explain the proteobacterial origin of a majority of S. elongatus xenologous genes. Expand
Conjugative transfer of clostridial shuttle vectors from Escherichia coli to Clostridium difficile through circumvention of the restriction barrier
Progress towards understanding the molecular basis of virulence in Clostridium difficile has been hindered by the lack of effective gene transfer systems. We have now, for the first time, developedExpand
Site-Specific Recombination in the Cyanobacterium Anabaena sp. Strain PCC 7120 Catalyzed by the Integrase of Coliphage HK022
ABSTRACT The integrase (Int) of the λ-like coliphage HK022 catalyzes the site-specific integration and excision of the phage DNA into and from the chromosome of its host, Escherichia coli. IntExpand
PifC and Osa, Plasmid Weapons against Rival Conjugative Coupling Proteins
TLDR
In silico analysis of FI proteins suggests that they represent recent acquisitions of conjugative plasmids, i.e., are not shared by members of the same plasmid species, which implies that FI are rapidly-moving accessory genes, possibly acting on evolutionary fights betweenplasmids for the colonization of specific hosts.

Electrotransformation of Haemophilus parasuis with in vitro modified DNA based on a novel shuttle vector.
TLDR
The established electrotransformation method and the novel shuttle vector pSHK4 constitute useful tools for the genetic manipulation of H. parasuis to gain a better understanding of the pathogen. Expand

Isolation and complementation of mutants of Anabaena sp. strain PCC 7120 unable to grow aerobically on dinitrogen
TLDR
A cosmid vector, pRL25C, containing replicons functional in Escherichia coli and in Anabaena species was constructed and a library of 1,054 cosmid clones was generated in E. coli DH1 bearing helper plasmid pDS4101, which was replicated to lawns of mutant AnabaENA strains with defects in the polysaccharide layer of the envelopes of the heterocysts.

Cloning and characterization of a DNA region encoding a stress-sensitive restriction system from Corynebacterium glutamicum ATCC 13032 and analysis of its role in intergeneric conjugation with Escherichia coli
TLDR
A rapid test procedure based on intergeneric conjugal plasmid transfer that permitted the distinction between restriction-negative and restriction-positive C. glutamicum clones was developed and proved that orf1 is essential for complementation, but inactivation of orf2 resulted in a small but significant increase in fertility.

It may be significant that ardA+ plasmids are authentic enterobacterial plasmsids and that type I restriction systems are associated historically with members of the Enterobacteriaceae. Expand
