The transcipients were obtained in intrageneric matings of E.coli donor harbouring the plasmid PR4::Mu cts 62 with Bac. cereus GP7 recipient cells with the frequency 10(-9). The transcipient clone Bac. cereus 682 was selected having stably inherited and expressed the hybrid plasmid PR4::Mu cts 62 genes for antibiotic resistance and temperature sensitivity. Production of the bacteriophage Mu cts 62 particles was not registered in the bacillary transcipient cells. The plasmid RP4::Mu cts 62 genes were localized in the chromosome of Bac. cereus 682 transcipient by the blot-hybridization technique with 32P-labelled DNA of the bacteriophage Mu cts 62 and the plasmid PR4. The transcipient of Bac. cereus 682 has the donor properties and transfers the RP4::Mu cts 62 genes to recipient cells of Bac. cereus DSM 318 with the frequency of 10(-6)-10(-7). The expression and transfer of the gram-negative plasmid genes in gram-positive bacterial cells are discussed.

UI MeSH Term Description Entries
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
D010957 Plasmids Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS. Episomes,Episome,Plasmid
D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli

D001409 Bacillus cereus A species of rod-shaped bacteria that is a common soil saprophyte. Its spores are widespread and multiplication has been observed chiefly in foods. Contamination may lead to food poisoning.
D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species. Species Specificities,Specificities, Species,Specificity, Species
D014169 Transformation, Bacterial The heritable modification of the properties of a competent bacterium by naked DNA from another source. The uptake of naked DNA is a naturally occuring phenomenon in some bacteria. It is often used as a GENE TRANSFER TECHNIQUE. Bacterial Transformation
D015964 Gene Expression Regulation, Bacterial Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in bacteria. Bacterial Gene Expression Regulation,Regulation of Gene Expression, Bacterial,Regulation, Gene Expression, Bacterial
