Precise Genome Modification via Sequence-Specific Nucleases-Mediated Gene Targeting for Crop Improvement
Genome editing technologies enable precise modifications of DNA sequences in vivo and offer a great promise for harnessing plant genes in crop improvement. The precise manipulation of plant genomes relies on the induction of DNA double-strand breaks by sequence-specific nucleases (SSNs) to initiate DNA repair reactions that are based on either non-homologous end joining (NHEJ) or homology-direc...
متن کاملSingle-strand-specific nucleases.
Single-strand-specific nucleases, which act on single-stranded nucleic acids and single-stranded regions in double-stranded nucleic acids, are multifunctional enzymes and are ubiquitous in distribution. They find wide application as analytical tools in molecular biology research, although enzymes such as P1 nuclease are also used for production of flavor enhancers such as 5' IMP and 5' GMP. Bec...
متن کاملTALE nucleases and next generation GM crops.
Site-specific and adaptable DNA binding domains are essential modules to develop genome engineering technologies for crop improvement. Transcription activator-like effectors (TALEs) proteins are used to provide a highly specific and adaptable DNA binding modules. TALE chimeric nucleases (TALENs) were used to generate site-specific double strand breaks (DSBs) in vitro and in yeast, Caenorhabditi...
متن کاملDevelopment of sequence-specific antimicrobials based on programmable CRISPR-Cas nucleases
Antibiotics target conserved bacterial cellular pathways or growth functions and therefore cannot selectively kill specific members of a complex microbial population. Here, we develop programmable, sequence-specific antimicrobials using the RNA-guided nuclease Cas91, 2 delivered by a bacteriophage. We show that Cas9 re-programmed to target virulence genes kills virulent, but not avirulent, Stap...
متن کاملDesign of artificial sequence-specific DNA bending ligands.
Proteins that bend DNA are important regulators of biological processes. Sequence-specific DNA bending ligands have been designed that bind two noncontiguous sites in the major groove and induce a bend in the DNA. An oligonucleotide containing pyrimidine segments separated by a central variable linker domain simultaneously binds by triple helix formation two 15-bp purine tracts separated by 10 ...
