Fuente: WIPO "biotechnology" The invention describes novel nucleotide sequences from genes which are produced upon induction with salicylic acid in tobacco plants. The genes can be used to confer resistance to pathogens in susceptible plants. Another part of the invention is formed by the promoters regulating expression of these genes. These promoters are switched on early in the response to pathogen attack and can be used as pathogen-inducible promoters.
