Abstract: The isolation of and methods of using a sub-genomic transcript (Sgt) promoter from Mirabilis mosaic virus (MMV) are described. A 333 bp MMV Sgt promoter fragment (sequence?306 to +27 from the transcription start site, TSS) was found to be sufficient for strongest promoter activity. This MMV Sgt promoter fragment shows comparable promoter activity to the MMV FLt promoter both in transgenic plants and in protoplasts. The MMV Sgt promoter also demonstrates much greater activity compared to Cauliflower mosaic virus (CaMV) 19S promoter and 35S promoter. The MMV Sgt promoter fragment and any chimeric gene to which it may be linked are usefull for plant geneic engineering to obtain transgenic plants, plant cells and seeds.

Abstract: The invention encompasses Drosophila Recombination Associated Protein (DRAP) isolated from D. melanogaster and a nucleic acid sequence encoding DRAP. The Drosophila Recombination Associated Protein, its homologues from other organisms or active peptides derived therefrom, as well as DNA encoding such protein are useful for homology-dependent pairing of three DNA strands. The combination of strand-transfer and topoisomerase activities associated with DRAP permits directed pairing and cleavage at defined site(s) within DNA. This in turn makes possible the isolation and/or removal of a defined segment of DNA. DRAP is also useful in cloning, genomic cloning and gene mapping, in promoting gene disruptions or “knockout” mutations, in carrying out targeted mutagenesis of specific genes and in generating transgenic animals.
