Abstract:
Recombinant DNA constructs, for use in plants and plant cells, have site-specific recombination sites that allow assessing phenotypes and modes of action by over expression or suppression of endogenous genes. In an aspect, a single DNA construct can be switched between over expression and suppression by the action of a recombinase such as the Cre recombinase on constructs having lox recombination sites. Other useful recombination systems include the Flp/frt system, the R/Rs system, the Dre/rox system, and the GIN/gix system.
Abstract:
The present invention is directed to controlling pest infestation by inhibiting one or more biological functions in an invertebrate pest. The invention discloses methods and compositions for use in controlling pest infestation by feeding one or more different recombinant double stranded RNA molecules to the pest in order to achieve a reduction in pest infestation through suppression of gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules, and to particular combinations of transgenic pesticidal agents for use in protecting plants from pest infestation.
Abstract:
Methods of, and compositions for, assembling one or more transcription units in a genome without a linked selectable marker or other unwanted transcription unit are provided. Also provided methods of, and compositions for, assembling one or more transcription units in a genome with a reduced frequency of vector backbone.
Abstract:
The invention provides novel uses of sequence-specific or sequence-directed endonucleases for molecular plant breeding. The invention also provides novel plant transformation vectors and expression cassettes, which include novel combinations of an endonuclease with plant expression and transformation elements. Plants and derivatives thereof produced by such methods are also provided.
Abstract:
The present invention relates to methods and compositions for improving the efficiency of Agrobacterium- and Rhizobium-mediated plant cell transformation by use of additional transformation enhancer sequences, such as overdrive or TSS sequences, operably linked to a T-DNA border sequence on a recombinant construct that comprises T-DNA.
Abstract:
This invention provides a method to autoregulate expression of a transgene susceptible to sRNA silencing by concomitantly transcribing RNA from DNA of a transgene and RNA from DNA from at least one sRNA silencing pathway gene. An aspect of the invention provides use of a recombinant DNA construct that includes DNA of a transgene and DNA of an sRNA silencing regulator. Also disclosed are transgenic cells and organisms having in their genome a recombinant DNA construct that includes DNA of a transgene and DNA of an sRNA silencing regulator.

Abstract:
Pesticidal proteins are provided that combine two or more modes of action into a single molecule. These pesticidal proteins therefor exhibit greater efficacy and/or durability of resistance, for the purposes of pest control, and can be utilized for pest control by provision in the diet of a pest organism, or by topical application to crop plants and/or pests. Methods and compositions for producing and using such proteins are also provided.
