Patent
CA 2725927
The invention provides an isolated polynucleotide comprising the sequence of SEQ ID NO: 1 or a variant thereof, wherein the variant encodes a polypeptide capable of modulating in a plant tolerance to at least one environmental stress selected from drought, cold, freezing, heat and salinity. The invention also provides construct, vectors, host cells, plant cells and plants genetically modified to comprise the polynucleotide. The invention also provides methods for producing and selecting plants that are tolerant to at least one environmental stress selected from drought, cold, freezing, heat and salinity, making use of the polynucleotides of the invention.
La présente invention concerne un polynucléotide isolé comprenant la séquence SEQ ID NO : 1 ou un variant de celle-ci, ledit variant codant pour un polypeptide capable de moduler chez une plante la tolérance à au moins un stress environnemental choisi parmi la sécheresse, le froid, le gel, la chaleur et la salinité. L'invention concerne également des constructions génétiques, des vecteurs, des cellules hôtes, des cellules végétales et des plantes génétiquement modifiées afin d'intégrer ledit polynucléotide. L'invention concerne encore des procédés de production et de sélection de plantes tolérantes à au moins un stress environnemental choisi parmi la sécheresse, le froid, le gel, la chaleur et la salinité, en faisant appel aux polynucléotides selon l'invention.
