    Abstract: The compositions and methods are provided that enhance the selection of transgenic plants having two T-DNA molecules integrated into a plant genome at different physical and genetic loci. The compositions are DNA constructs that comprise novel arrangements of T-DNA molecules containing genes of interest, positive selectable marker genes, and conditional lethal genes. The methods disclosed herein comprises transforming a plant cell to comprise the DNA constructs of the present invention, regenerating the plant cell into a plant and identifying independent transgene loci, where the selectable marker genes or transgenic elements can be segregated in the progeny.

    Abstract: The present invention provides gene targets, constructs and methods for the genetic control of plant disease caused by multiple plant viruses. The present invention relates to achieving a plant protective effect through the identification of target coding sequences and the use of recombinant DNA technologies for post-transcriptionally repressing or inhibiting expression of the target coding sequences of plant-parasitic viruses. Protein-expression based approaches may also be utilized to augment phenotype resistance. Thus, transcription of a single transgenic event comprising one or more plant expression cassettes can allow for broad spectrum resistance of a plant to multiple plant viral strains and species among the geminiviruses, tospoviruses, and potexviruses.

    Abstract: 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.
