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.

US Classification:

536 241, 4353201, 435419, 435468

Abstract:

The present invention provides promoters from plants capable of driving gene expression in plant cells. The promoters vary in strength and in tissue specificity, and can be used to facilitate the development of transgenic plants in which tissue preferred expression, constitutive expression, and the strength of transgene expression is either more or less critical.
