CA 2298768

The novel constructs and methods of this invention improve tolerance in plants to environmental stresses and senescence. Nucleic acids encoding a plant farnesyl transferase are described, as are transgenic plants and seeds incorporating these nucleic acids and proteins. Also provided are inhibitors of naturally-occurring farnesyl transferase which, when expressed, will enhance drought tolerance in the plants, improve resistance to senescence and modify growth habit.

L'invention concerne des produits de synthèse et des procédés nouveaux qui permettent d'améliorer la résistance des plantes à différents types de stress environnemental et au vieillissement. On décrit des acides nucléiques codant une farnésyle-transférase de plante, ainsi que des semences et des plantes transgéniques incorporant les acides nucléiques et les protéines considérés. L'invention concerne également des inhibiteurs de farnésyle-transférase naturelle qui, une fois exprimés, améliorent la résistance des plantes à la sécheresse et leur résistance au vieillissement, et modifient par ailleurs leur type de développement.
