Abstract
The present invention describes a method for the induction of resistance in a plant host to a RNA or DNA virus pathogenic to the plant which comprises isolating a fragment of viral RNA or DNA associated with the replicase portion of the virus genome, specifically a portion that does not involve a read-through portion of the gene, and integrating a DNA copy of the isolated fragment or a portion thereof into the genome of a recipient plant in such a manner that the plant becomes transformed with the inserted fragment.
Claims22
A DNA molecule comprising:
- a promoter region;
- a structural gene encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion, wherein said structural gene is operably linked to said promoter region;
- and
- a 3' non-translated region which is operably linked to said structural gene and functions in plant cells to cause the termination of transcription.
An expression vector containing a DNA molecule encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion.
A transgenic plant cell transformed to express a DNA molecule encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion.
A transgenic plant seed transformed to express a DNA molecule encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion.
A transgenic plant transformed to express a DNA molecule encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion.
A method of imparting disease resistance to plants comprising:
- forming a transgenic plant cell transformed to express a DNA molecule encoding a replicase protein or polypeptide for a plant pathogenic virus which does not have a replicase read through portion.
