摘要: This invention relates to methods of controlling gene expression or gene suppression in eukaryotic cells. One aspect of this invention includes modifying the degree of silencing of a target gene by use of a modified suppression element. Another aspect includes providing a eukaryotic cell having a desired phenotype resulting from transcription in the eukaryotic cell of a modified suppression element. Also provided are transgenic eukaryotic cells, transgenic plant cells, plants, and seeds containing modified suppression elements, and useful derivatives of such transgenic plant cells, plants, or seeds, such as food or feed products.

摘要: 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.
