Abstract
A process for the maintenance and proliferation of defective, non-infectious viruses or virus genomes, comprising mutations, i.e. deletions, substitutions, insertions and new rearrangements of the viral genes or combinations of the virus DNA with heterologous genetic material in proliferating plant material and for the regeneration of whole plants containing stably integrated into their genome said defective, non-infectious virus DNA.
