The present invention relates to Constitutive Triple Response-like (CTR1-like) nucleic acid sequences and the sugar and lipid metabolism regulator proteins encoded by the said nucleic acid sequences. Further, the present invention relates to the use of the aforementioned nucleic acid sequences and proteins in transgenic plants. In particular, the invention is directed to methods for manipulating sugar-related compounds and for increasing oil level and altering the fatty acid composition in plants and seeds. The invention further relates to methods of using these novel plant polypeptides to stimulate plant growth and/or to increase yield and/or composition of seed storage compounds. L'invention concerne des séquences d'acides nucléiques de type triple réponse constitutive (de type CTR1) et les protéines régulatrices du métabolisme du sucre et des lipides codées par lesdites séquences. De plus, l'invention concerne l'utilisation des séquences d'acides nucléiques et des protéines susmentionnées dans des végétaux transgéniques. Plus précisément, l'invention concerne des procédés permettant de manipuler des composés relatifs au sucre et permettant d'augmenter le taux d'huile et de modifier la composition d'acides gras dans des végétaux et des semences. L'invention concerne également des procédés d'utilisation de ces polypeptides végétaux aux fins de stimulation de la croissance des végétaux et/ou d'augmentation de la production et/ou la composition de composés de stockage de semences.
