A viroid-derived system to produce large amounts of recombinant RNA in Escherichia coli.

ABSTRACT: Viruses have been engineered into useful biotechnological tools for gene therapy or to induce the synthesis of products of interest, such as therapeutic proteins and vaccines, in animal and fungal cells, bacteria or plants. Viroids are a particular class of infectious agents of higher plants that exclusively consist of a small non-protein-coding circular RNA molecule. In the same way as viruses have been transformed into useful biotechnological devices, can viroids be converted into beneficial tools? We show herein that, by expressing Eggplant latent viroid (ELVd) derived RNAs in Escherichia coli together with the eggplant tRNA ligase, this being the enzyme involved in viroid circularization in the infected plant, RNAs of interest like aptamers, extended hairpins, or other structured RNAs
