Cre recombinase-mediated site-specific recombination between plant chromosomes.
We report the use of the bacteriophage P1 Cre-lox system for generating conservative site-specific recombination between tobacco chromosomes. Two constructs, one containing a promoterless hygromycin-resistance gene preceded by a lox site (lox-hpt) and the other containing a cauliflower mosaic virus 35S promoter linked to a lox sequence and the cre coding region (35S-lox-cre), were introduced se...
متن کاملFLP Recombinase-Mediated Site-Specific Recombination in Silkworm, Bombyx mori
A comprehensive understanding of gene function and the production of site-specific genetically modified mutants are two major goals of genetic engineering in the post-genomic era. Although site-specific recombination systems have been powerful tools for genome manipulation of many organisms, they have not yet been established for use in the manipulation of the silkworm Bombyx mori genome. In th...
متن کاملIntermediates in serine recombinase-mediated site-specific recombination.
Site-specific recombinases are enzymes that promote precise rearrangements of DNA sequences. They do this by cutting and rejoining the DNA strands at specific positions within a pair of target sites recognized and bound by the recombinase. One group of these enzymes, the serine recombinases, initiates strand exchange by making double-strand breaks in the DNA of the two sites, in an intermediate...
متن کاملCre-mediated somatic site-specific recombination in mice.
Conditional mutant mice equipped with heterologous recombination systems (Cre/lox or Flp/frt) are promising for studying tissue-specific gene function and for designing better models of human diseases. The utility of these mice depends on the cell target specificity, on the efficiency and on the control over timing of gene (in)activation. We have explored the utility of adenoviral vectors and t...
متن کاملMicroinjection of cre recombinase RNA induces site-specific recombination of a transgene in mouse oocytes.
We have developed a strategy for producing single copy transgenic mouse lines using Cre-loxP site specific recombination. The method is based on transient expression of the recombinase after injection of in vitro transcribed mRNA into the cytoplasm of fertilised eggs containing multiple copies of the transgene. The success rate of the recombination event is 100% (15 out of 15).
