    摘要: Compositions and methods are provided for modifying a nucleotide sequence in the genome of a plant cell, without the use of a selectable marker. The methods and compositions employ a guide polynucleotide/Cas endonuclease system to make a double strand break in a target site located in a nucleotide sequence and plant cells are obtained without the use of a selectable marker, and to provide an effective system for modifying target sites within the genome of a plant, plant cell or seed. Compositions and methods are also provided for producing a plant cell, callus tissue or plant having a modified nucleotide sequence in its genome, without the use of a selectable marker.

    摘要: The present invention provides gene editing systems comprising gene editing dimerization switches comprising a first and second gene editing switch domain that allow for the regulation of a gene editing function by the introduction, e.g., administration, of a gene editing dimerization molecule having the ability to bring together a first gene editing switch domain and a second gene editing switch domain. A regulated gene editing function provides, e.g., less off-target side effects, and increases the therapeutic window. The present invention also provides improved FKBP/FRB-based dimerization switches wherein the FRB switch domain or the FKBP switch domain, or both the FRB and FKBP switch domains, comprise one or more mutations that optimize performance, e.g., that alter, e.g., enhance the formation of a complex between the first switch domain, the second switch domain, and the dimerization molecule, rapamycin, or a rapalog, e.g., RAD001.

    摘要: A composition is disclosed that comprises at least one protein component of an RNA-guided endonuclease (RGEN) and at least one cell-penetrating peptide (CPP), wherein the RGEN protein component and CPP are covalently or non-covalently linked to each other in an RGEN protein-CPP complex. The RGEN protein-CPP complex can traverse (i) a cell membrane, or (ii) a cell wall and cell membrane, of a cell. The RGEN protein component of an RGEN protein-CPP complex in certain embodiments can be associated with a suitable RNA component to provide an RGEN capable of specific DNA targeting. Further disclosed are compositions comprising at least one protein component of a guide polynucleotide/Cas endonuclease complex and at least one CPP, as well as methods of delivering RGEN proteins into microbial cells, as well as methods of targeting DNA with RGENs.
