This invention describes novel DNA sequences that function as promoters of transcription of associated nucleotide sequences. More specifically, this invention describes DNA sequences conferring constitutive expression to an associated nucleotide sequence. The invention also describes recombinant sequences containing such promoter sequences. The said recombinant DNA sequences may be used to create transgenic plants, but especially plants expressing a nucleotide sequence of interest at all times and in most tissues and organs.

Cestrum yellow leaf curling virus promoters

A novel process for the direct transfer of foreign genes to plant genomes is described. The novel process comprises placing a gene under the control of plant expression signals and transferring it, by contact with protoplasts without the aid of natural systems for infecting plants, direct to plant cells from which genetically transformed plants can subsequently be derived.

Transformation of hereditary material of plants

The present invention relates to a novel method of inserting viral DNA, which optionally may contain cargo-DNA, into plants or viable parts thereof, but preferably into plants of the monocotyledon class, and most preferably into plants of the family Gramineae, using suitable transfer microorganisms. Further comprised by the invention are recombinant DNA, plasmid and vector molecules suitably adapted to the specific conditions of the process according to the invention and the transgenic plant products obtainable in accordance with the said process.

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.
