The need for an easy-to-use and reliable nuclease is especially high in plant research, as precise genome In this report, we have shown that the use of CRISPR‐Cas9 allows efficient targeted mutagenesis and significantly improves GT efficiency and precision in P. patens, expanding the range of available tools for gene function analysis in this model organism and facilitating the production of moss‐made pharmaceutical, a very promising new area of biotechnology (Reski et al., 2015). Although CRISPR/Cas systems can have on-target cleavage rates close to the transfection rates, they may also have relatively high off-target cleavage at similar genomic sites that contain one or more base pair mismatches, and insertions or deletions relative to the guide strand. technique allowing for site-directed mutation in the plant genome is the CRISPR Cas9 method. Before explaining how the CRISPR Cas9 method can be used for prokaryote genome editing, the inheritable prokaryotic immune system has to be outlined as the CRISPR technique is based upon this natural phenomena (Jinek et al., 2012).

Martin1,2* Abstract CRISPR assisted homology directed repair enables the introduction of virtually any modification to the Saccharomyces cerevisiae genome. 2020-01-01 · Before the advent of CRISPR or other technologies based on the activity of site-specific endonucleases—e.g., zinc finger nuclease, ZFN (Urnov et al., 2010) and transcription activator-like effector nuclease, TALEN —the only possible strategy to perform targeted mutagenesis in model organisms was based on homologous recombination in ES cells, a transgenesis method only available for mammals CRISPR/Cas9-based site-directed mutagenesis in vivo was achieved using either the Cauliflower mosaic virus 35S or M. polymorpha EF1α promoter to express Cas9. Isolated mutant individuals showing an auxin-resistant phenotype were not chimeric. Moreover, stable mutants were produced by asexual reproduction of T 1 plants.
