Role of natural transformation in the evolution of small cryptic plasmids in Synechocystis sp. PCC 6803
(2023)
Small cryptic plasmids have no clear effect on the host fitness and theirfunctional repertoire remains obscure. The naturally competent cyanobacte-riumSynechocystissp. PCC 6803 harbours several small cryptic plasmids;whether ...
Plasmids in Salmonella typhi in Lima, Peru, 1987-1988: epidemiology and lack of association with severity of illness or clinical complications
(American Society of Tropical Medicine and Hygiene, 1992)
A prospective study was conducted to better characterize the epidemiology of plasmid-bearing strains of Salmonella typhi in an endemic area of Lima, Peru, and to determine if plasmids were associated with specific ...
Conjugal transfer of a Sinorhizobium meliloti cryptic plasmid evaluated during a field release and in soil microcosms
(Elsevier France-editions Scientifiques Medicales Elsevier, 2013-03)
Horizontal gene transfer (HGT) is a central evolutionary mechanism that mediates the diversification and adaptation of bacteria in general and of rhizobia in particular. The few quantitative data on the conjugal transfer ...
Sequence analysis of pLBB1, a cryptic plasmid from Lactobacillus delbrueckii subsp. bulgaricus
(National Research Council Canada-NRC Research Press, 2002-02-21)
The first report of the complete nucleotide sequence of a cryptic plasmid from Lactobacillus delbrueckii subsp. bulgaricus (Lactobacillus bulgaricus) is presented. The plasmid pLBB1 consists of 6127 bp with a GC content ...
Endophytic population of Pantoea agglomerans in citrus plants and development of a cloning vector for endophytes
(WILEY-V C H VERLAG GMBH, 2008)
Harmless bacteria inhabiting inner plant tissues are termed endophytes. Population fluctuations in the endophytic bacterium Pantoea agglomerans associated with two species of field cultured citrus plants were monitored ...
Characterization of a small cryptic plasmid from endophytic Pantoea agglomerans and its use in the construction of an expression vector
(Sociedade Brasileira de Genética, 2011)
A circular cryptic plasmid named pPAGA (2,734 bp) was isolated from Pantoea agglomerans strain EGE6 (an endophytic bacterial isolate from eucalyptus). Sequence analysis revealed that the plasmid has a G+C content of 51% ...
Complete sequence of three plasmids from Bacillus thuringiensis INTA-FR7-4 environmental isolate and comparison with related plasmids from the Bacillus cereus group
(Academic Press Inc Elsevier Science, 2009-11)
Bacillus thuringiensis is an insect pathogen used worldwide as a bioinsecticide. It belongs tothe Bacillus cereus sensu lato group as well as Bacillus anthracis and B. cereus. Plasmids fromthis group of organisms have been ...
A CsrA/RsmA translational regulator gene encoded in the replication region of a Sinorhizobium meliloti cryptic plasmid complements Pseudomonas fluorescens rsmA/E mutants
(Society for General Microbiology, 2012-11)
Members of the CsrA/RsmA family are global regulatory proteins that bind to mRNAs, usually at the ribosome-binding site, to control mRNA translation and stability. Their activity is counteracted by small non-coding RNAs ...
