Double strand break-induced recombination in Chlamydomonas reinhardtii chloroplasts.
The mechanisms of chloroplast recombination are largely unknown. Using the chloroplast-encoded homing endonuclease I-CreI from Chlamydomonas reinhardtii, an experimental system is described that allows the study of double strand break (DSB)-induced recombination in chloroplasts. The I-CreI endonuclease is encoded by the chloroplast ribosomal group I intron of C.reinhardtii and cleaves specifica...
متن کاملDouble-strand-break-induced homologous recombination in mammalian cells.
In mammalian cells, the repair of DNA double-strand breaks (DSBs) occurs by both homologous and non-homologous mechanisms. Indirect evidence, including that from gene targeting and random integration experiments, had suggested that non-homologous mechanisms were significantly more frequent than homologous ones. However, more recent experiments indicate that homologous recombination is also a pr...
متن کاملDouble-strand break repair and homologous recombination in Schizosaccharomyces pombe.
The study of double-strand break repair and homologous recombination in Saccharomyces cerevisiae meiosis has provided important information about the mechanisms involved. However, it has become clear that the resulting recombination models are only partially applicable to repair in mitotic cells, where crossover formation is suppressed. In recent years our understanding of double-strand break r...
متن کاملSnapShot: Homologous Recombination in DNA Double-Strand Break Repair
Homologous recombination (HR) provides an important mechanism to repair both accidental and programmed DNA double-strand breaks (DSBs) during mitosis and meiosis. Defects in HR are associated with mutagenesis and predispose to cancer, highlighting the importance of this pathway for preserving genome integrity (Moynahan and Jasin, 2010). HR is active in the S and G2 phases of the cell cycle wher...
متن کاملDouble-strand break-induced mitotic intrachromosomal recombination in the fission yeast Schizosaccharomyces pombe.
The Saccharomyces cerevisiae HO gene and MATa cutting site were used to introduce site-specific double-strand breaks (DSBs) within intrachromosomal recombination substrates in Schizosaccharomyces pombe. The recombination substrates consisted of nontandem direct repeats of ade6 heteroalleles. DSB induction stimulated the frequency of recombinants 2000-fold. The spectrum of DSB-induced recombinan...
