Abstract
Transgenic plants with increased resistance to geminivirus infection, and nucleic acid constructs useful in producing such plants, are described. The transgenic plants express a mutant AL3/C3 geminivirus protein, which increases resistance to infection by at least one geminivirus, compared to a non-transformed control plant.
Claims19
An isolated nucleic acid construct comprising an expression cassette, which construct comprise , in the 5′ to 3′ direction,
- (a) a promoter operable in plant cell,
- (b) a nucleic acid sequence encoding a mutant AL3/C3 protein, said nucleic acid sequence located downstream from said promoter and operatively associated therewith, and
- (c) a termination sequence positioned downstream from said nucleic acid sequence and operatively associated therewith;
- wherein said nucleic acid sequence encoding a mutant AL3/C3 protein comprises a nucleotide sequence encoding a protein having a sequence selected from the group consisting of:
- SEQ ID NO:
- 19 and
- SEQ ID NO:
- 26.
