    • The invention relates to genetic manipulations of eukaryotic organisms, with recombinant DNA comprising RNA virus derived sequences for protecting such organisms against RNA viruses or enabling inducible or tissue-specific production of foreign proteins/peptides or RNAs. One embodiment of the recombinant DNA according to the invention comprises recombinant DNA, comprising two, 12-1250 base pair long, inverted repeat nucleotide sequences with therebetween at least one nucleotide sequence which is derived from RNA virus which for its replication is dependent upon a viral RNA/RNA polymerase, said RNA virus derived sequence comprising at least cis elements for replication but no gene that codes for viral RNA/RNA polymerase and no gene that codes for viral coat protein. The invention also relates to eukaryotic or prokaryotic cells or organisms which incorporate the recombinant DNA according to the invention. Further the invention relates to a method of protecting such cells or organisms by genetically incorporating recombinant DNA according to the invention.
    • 本发明涉及真核生物的遗传操作,其中重组DNA包含RNA病毒衍生的序列,用于保护这些生物体免受RNA病毒的侵袭或使得诱导或组织特异性产生外源蛋白/肽或RNA。 根据本发明的重组DNA的一个实施方案包含重组DNA,其包含两个12-1250碱基对长的反向重复核苷酸序列,其间具有至少一个核苷酸序列,其衍生自RNA病毒,其复制依赖于病毒 RNA / RNA聚合酶,所述RNA病毒衍生序列至少包含用于复制的顺式元件,但没有编码病毒RNA / RNA聚合酶的基因,并且没有编码病毒外壳蛋白的基因。 本发明还涉及掺入根据本发明的重组DNA的真核或原核细胞或生物体。 此外,本发明涉及通过遗传掺入根据本发明的重组DNA来保护此类细胞或生物体的方法。
