NOVEL NUCLEIC ACID SEQUENCES AND THEIR USE IN METHODS FOR ACHIEVING PATHOGEN RESISTANCE IN PLANTS

摘要

The invention relates to novel RacB cDNA sequences from barley and to expression cassettes and vectors comprising said promoter sequences. The invention also relates to transgenic plants transformed with said expression cassettes or vectors, cultures derived therefrom, fragments or transgenic propagating material and to the use thereof in the production of foodstuffs, animal food, seeds, pharmaceuticals or fine chemicals. The invention further relates to the production or enhancement of pathogen resistance in plants by reducing the expression of an RacB protein or a functional equivalent.
