CA 2751920

The present invention relates to the use of trehalase to obtain drought and/or salt resistance in plants. More specifi-cally, it relates to genetically modified constructs, transformed into plants and resulting in overexpression of trehalase, whereby the transformed plants show a significantly better drought resistance during the drought period, and a better recovery when water is supplied after the drought period.

La présente invention concerne l'utilisation de tréhalase en vue d'obtenir une résistance à la sécheresse et/ou au sel dans des végétaux. Plus spécifiquement, l'invention porte sur des constructions génétiquement modifiées, transformées en végétaux et entraînant la surexpression de la tréhalase. Lesdits végétaux transformés présentent une résistance à la sécheresse nettement améliorée durant la période de sécheresse, et une meilleure récupération lorsque de l'eau est fournie après ladite période de sécheresse.
