Abstract
Compositions and methods for enhancing disease resistance in plants are provided. The method involves transforming a plant with an avirulence gene or alternatively with an avirulence gene and the complementing resistance gene. A pathogen inducible promoter or alternatively a weak constitutive promoter is used to control the desired level of disease control in the plant. Transformed plants, plant cells, tissues, and seed are also provided having enhanced disease resistance.
Claims10
A method for creating or enhancing disease resistance in a monocotyledonous plant to Fusarium, said method comprising transforming said plant with an expression cassette comprising the coding sequence of the AvrRxv avirulence gene operably linked to a promoter, wherein said promoter is selected from the group consisting of the core promoter of the Rsyn7 promoter and the core promoter of the 35S CaMV promoter, and regenerating stably transformed plants with enhanced disease resistance to Fusarium.
A monocot plant stably transformed with a DNA construct comprising the coding sequence of the AvrRxv avirulence gene operably linked to a promoter, wherein said promoter is selected from the group consisting of the core promoter of the Rsyn7 promoter and the core promoter of the 35S CaMV promoter.
A monocot plant cell comprising in its genome a DNA construct comprising the coding sequence of the AvrRxv avirulence gene operably linked to a promoter, wherein said promoter is selected from the group consisting of the core promoter of the Rsyn7 promoter and the core promoter of the 35S CaMV promoter.
