Abstract
In accordance with the present invention, there are provided transgenic plants comprising a plurality of plant-defense-associated proteins that are expressed to produce such proteins in an amount sufficient to increase the plants resistance to plant pathogens, relative to non-transgenic plants of the same species. The transgenic plants are useful to study patterns of development, and to provide increased resistance to plant pathogens when grown in crops as a food source, and the like. Nucleic acid constructs are also provided that are useful in methods for producing the invention transgenic plants.
Claims10
A transgenic plant comprising:
- a first exogenous transgene encoding an overexpressed and biologically active rice chitinase protein;
- and
- a second exogenous transgene encoding an overexpressed and biologically active alfalfa glucanase protein,
- wherein:
- said transgenes are constitutively expressed, and
- said plant has increased resistance to fungal pathogens relative to plants that do not constitutively express both of said transgenes.
A nucleic acid construct comprising:
- a first transgene encoding a biologically active rice chitinase protein;
- and
- a second transgene encoding a biologically active alfalfa glucanase protein, and
- wherein each of said transgenes are operatively linked to a plant-functional promoter.
A method to increase fungal disease resistance of a transgenic plant containing a transgene encoding a biologically active rice chitinase protein, said method comprising:
- introducing a transgene encoding a biologically active alfalfa glucanase protein into the genome of said plant, wherein at least one transgene is heterologous to said plant.
A method to increase fungal disease resistance of a transgenic plant containing a transgene encoding a biologically active alfalfa glucanase protein, said method comprising:
- introducing a transgene encoding a biologically active rice chitinase protein into the genome of said plant, wherein at least one transgene is heterologous to said plant.
