This invention describes pathogen-inducible promoters which normally drive expression of plant hexose oxidases, especially those which can be isolated from Helianthus annuus and Lactuca sativa, more specifically those promoters which naturally are the regulatory regions driving expression of the hexose oxidase MS59 and WL64, respectively. Also claimed are chimeric constructs where these pathogen-inducible promoters drive expression of antipathogenic proteins or of proteins which can elicit a hypersensitive response.

L'invention concerne des promoteurs inductibles par les pathogènes, qui normalement contrôlent l'expression des hexose oxydases végétales, notamment les promoteurs qui peuvent être isolés à partir de Helianthus annuus et de Lactuca sativa, et plus particulièrement les promoteurs qui, naturellement, sont les régions régulatrices, dénommées MS59 et WL64, contrôlant l'expression des hexose oxydases. L'invention concerne également des constructions chimères dans lesquelles ces promoteurs inductibles par les pathogènes contrôlent l'expression de protéines antigéniques ou de protéines pouvant provoquer une réponse d'hypersensibilité.
