20090070898 | Plant microRNAs and methods of use thereof - This invention discloses novel microRNAs and their precursors, and recombinant DNA constructs including such novel miRNAs, miRNA precursors, miRNA promoters, and miRNA recognition sites corresponding to the miRNAs. Included are novel miRNA and miRNA precursors that exhibit nutrient-responsive expression. Also disclosed are miRNA decoy sequences. Further provided are non-natural transgenic plant cells, plants, and seeds containing in their genome a recombinant DNA construct of this invention and methods of controlling gene expression using recombinant DNA constructs of this invention. | 03-12-2009 |
20110296555 | Recombinant DNA Constructs and Methods for Modulating Expression of a Target Gene - This invention provides recombinant DNA constructs and methods for manipulating expression of a target gene that is regulated by a small RNA, by interfering with the binding of the small RNA to its target gene. More specifically, this invention discloses recombinant DNA constructs encoding cleavage blockers, 5-modified cleavage blockers, and translational inhibitors useful for modulating expression of a target gene and methods for their use. Further disclosed are miRNA targets useful for designing recombinant DNA constructs including miRNA-unresponsive transgenes, miRNA decoys, cleavage blockers, 5-modified cleavage blockers, and translational inhibitors, as well as methods for their use, and transgenic eukaryotic cells and organisms containing such constructs. | 12-01-2011 |
20130232644 | PHASED SMALL RNAS - This invention discloses recombinant DNA constructs encoding phased small RNAs useful in regulating expression of one or more genes of interest. Also disclosed by this invention are transgenic plant cells, plants, and seeds containing a recombinant DNA construct of this invention | 09-05-2013 |
