Journal ArticleDOI
Rapid "open-source" engineering of customized zinc-finger nucleases for highly efficient gene modification.
Morgan L. Maeder,Stacey Thibodeau-Beganny,Anna Osiak,David A. Wright,Reshma M. Anthony,Magdalena Eichtinger,Tao Jiang,Jonathan E. Foley,Ronnie J. Winfrey,Jeffrey A. Townsend,Erica Unger-Wallace,Jeffry D. Sander,Felix Müller-Lerch,Fengli Fu,Joseph Pearlberg,Carl Göbel,Justin P. Dassie,Shondra M. Pruett-Miller,Matthew H. Porteus,Dennis C. Sgroi,A. John Iafrate,Drena Dobbs,Paul B. McCray,Toni Cathomen,Daniel F. Voytas,J. Keith Joung +25 more
TL;DR: OP (Oligomerized Pool ENgineering), a rapid, publicly available strategy for constructing multifinger arrays, which is more effective than the previously published modular assembly method and provides an "open-source" method for rapidly engineering highly active zinc-finger arrays.
Journal ArticleDOI
High-frequency modification of plant genes using engineered zinc-finger nucleases
Jeffrey A. Townsend,David A. Wright,Ronnie J. Winfrey,Fengli Fu,Morgan L. Maeder,J. Keith Joung,Daniel F. Voytas +6 more
TL;DR: High-frequency ZFN-stimulated gene targeting at endogenous plant genes, namely the tobacco acetolactate synthase genes (ALS SuRA and SuRB), for which specific mutations are known to confer resistance to imidazolinone and sulphonylurea herbicides are demonstrated.
Journal ArticleDOI
Unexpected failure rates for modular assembly of engineered zinc fingers
Cherie L. Ramirez,Jonathan E. Foley,David A. Wright,Felix Müller-Lerch,Shamim H. Rahman,Tatjana I. Cornu,Ronnie J. Winfrey,Jeffry D. Sander,Fengli Fu,Jeffrey A. Townsend,Toni Cathomen,Daniel F. Voytas,J. Keith Joung +12 more
TL;DR: In the version of this correspondence initially published, the two previously published datasets analyzed were labeled with incorrect references in Figure 1b.
Journal ArticleDOI
High‐frequency homologous recombination in plants mediated by zinc‐finger nucleases
David A. Wright,Jeffrey A. Townsend,Ronnie J. Winfrey,Phillip A. Irwin,Jyothi Rajagopal,Patricia M. Lonosky,Bradford D. Hall,Michael D. Jondle,Daniel F. Voytas +8 more
TL;DR: It is demonstrated that chromosome breaks created by zinc-finger nucleases greatly enhance the frequency of localized recombination in tobacco test system, suggesting that plant genome engineering through homologous recombination can now be reliably accomplished using zinc- finger nucleases.
Journal ArticleDOI
Standardized reagents and protocols for engineering zinc finger nucleases by modular assembly.
David A. Wright,Stacey Thibodeau-Beganny,Jeffry D. Sander,Ronnie J. Winfrey,Andrew S. Hirsh,Magdalena Eichtinger,Fengli Fu,Matthew H. Porteus,Drena Dobbs,Daniel F. Voytas,J. Keith Joung +10 more
TL;DR: A comprehensive, publicly available archive of plasmids encoding more than 140 well-characterized zinc finger modules together with complementary web-based software for identifying potential zinc finger target sites in a gene of interest is described.
