Towards targeted mutagenesis and gene replacement in plants.

Abstract : Advances in the development of biotechnological tools for plant gene disruption and repair have lagged behind the rapid progress made in whole-genome sequencing of many model and crop plant species. Plant DNA-repair machinery predominantly uses non-homologous end-joining (NHEJ), making the homologous recombination (HR)-based methods, which have proved fruitful for gene targeting in non-plant systems, unsuitable for use in plant systems. Two recent reports describe successful targeted mutagenesis and gene targeting in Arabidopsis by either harnessing the plant NHEJ machinery using site-specific induction of double-strand breaks (DSBs), or by activation of a HR pathway through overexpression of a yeast DNA recombination gene in transgenic plants. These reports provide a foundation from which new technologies for site-specific genome alterations in plant species can be developed.
