  • Promoter inductible in plants, sequence incorporating same and resulting product
    Patent number: 6677505
    Abstract: The invention concerns a set of plant promoters inductible by biotic or abiotic stresses, in particular by pathogens, their use, expression vectors comprising said promoters and a gene of interest, cells and/or plants transformed by said vectors. The invention also concerns methods for obtaining said cells and plants, said transformed plants with improved resistance to said pathogens.
