CA 2702592
Methods and compositions for modulating plant development are provided. Polynucleotide sequences encoding ZmSNAC polypeptides are provided, as are the amino acid sequences of the encoded polypeptides. The sequences can be used in a variety of methods including modulating root development, modulating floral development, modulating leaf and/or shoot develop-ment, modulating senescence, modulating seed size and/or weight, and modulating tolerance of plants to abiotic stress. Transformed plants, plant cells, tissues, and seed are also provided. A stress-inducible ZmSNAC1 promoter is also provided.
L'invention concerne des procédés et des compositions pour moduler le développement des plantes. Elle concerne des séquences polynucléotidiques codant des polypeptides de ZmSNAC, ainsi que les séquences d'acides aminés des polypeptides codés. Les séquences peuvent être utilisées dans divers procédés incluant la modulation du développement racinaire, la modulation du développement floral, la modulation du développement des feuilles et/ou des pousses, la modulation de la sénescence, la modulation de la taille et/ou du poids des graines, et la modulation de la tolérance des plantes au stress abiotique. L'invention concerne également des plantes, des cellules végétales, des tissus et des graines transformés. Elle concerne également un promoteur de ZmSNAC1 inductible par le stress.
