    摘要: The present invention provides molecular constructs and methods for use thereof, including constructs including heterologous miRNA recognition sites, constructs for gene suppression including a gene suppression element embedded within an intron flanked on one or on both sides by non-protein-coding sequence, constructs containing engineered miRNA or miRNA precursors, and constructs for suppression of production of mature microRNA in a cell. Also provided are transgenic plant cells, plants, and seeds containing such constructs, and methods for their use. The invention further provides transgenic plant cells, plants, and seeds containing recombinant DNA for the ligand-controlled expression of a target sequence, which may be endogenous or exogenous. Also disclosed are novel miRNAs and miRNA precursors from crop plants including maize and soy.

    摘要: 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.
