Abstract
This invention discloses transgenic plants, such as transgenic tobacco and potato, having resistance to multiple viral taxonomic groups using parts of the 2,5A oligoadenylate pathway. In particular, said plants are genetically engineered to contain a DNA sequence encoding at least one polypeptide having a 2,5A synthetase activity. By this means a step in the 2,5A oligoadenylate pathway heretofore believed to be missing in all plants is provided so that viral infection in the transgenic plants is inhibited via a 2,5A dependent endonuclease. Moreover, this invention relates to a process for the production of said transgenic plants by transfection with a genetically engineered DNA sequence encoding at least one polypeptide having a 2,5A synthetase activity.
