RIBOZYME COUPLED TO AN ANTISENSE RNA SEQUENCE, GENE ENCODING IT AND USE AS ANTIVIRAL AGENT IN PLANTS

摘要

Host cells can be transformed so that they express ribozyme RNA and antisense RNA which are connected together via a spacer. The RNA molecules can be complementary, for example, to a particular viral RNA. Plants which are transformed with genes coding for such RNA display a significantly improved defence against viruses.
