Site-specific integration of transgenes in soybean via recombinase-mediated DNA cassette exchange.
A targeting method to insert genes at a previously characterized genetic locus to make plant transformation and transgene expression predictable is highly desirable for plant biotechnology. We report the successful targeting of transgenes to predefined soybean (Glycine max) genome sites using the yeast FLP-FRT recombination system. First, a target DNA containing a pair of incompatible FRT sites...
متن کاملReproducible doxycycline-inducible transgene expression at specific loci generated by Cre-recombinase mediated cassette exchange
Comparative analysis of mutants using transfection is complicated by clones exhibiting variable levels of gene expression due to copy number differences and genomic position effects. Recombinase-mediated cassette exchange (RMCE) can overcome these problems by introducing the target gene into pre-determined chromosomal loci, but recombination between the available recombinase targeting sites can...
متن کاملCre/lox-Recombinase-Mediated Cassette Exchange for Reversible Site-Specific Genomic Targeting of the Disease Vector, Aedes aegypti
Site-specific genome modification (SSM) is an important tool for mosquito functional genomics and comparative gene expression studies, which contribute to a better understanding of mosquito biology and are thus a key to finding new strategies to eliminate vector-borne diseases. Moreover, it allows for the creation of advanced transgenic strains for vector control programs. SSM circumvents the d...
متن کاملCre 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 کاملSite-directed integration of the cre gene mediated by Cre recombinase using a combination of mutant lox sites.
The Cre-lox system is an important tool for genetic manipulation. To promote integrative reactions, two strategies using mutant lox sites have been developed. One is the left element/right element (LE/RE)-mutant strategy and the other is the cassette exchange strategy using heterospecific lox sites such as lox511 or lox2272. We compared the recombination efficiencies using these mutant lox site...
