d'une protéine ayant une fonction de senseur général de glucose codée par le gène GGS1 ou un gène similaire ; d'une protéine transporteur membranaire (perméase) du glucose à faible affinité; d'un sucre kinase. Yeast strains transformed or modified so as to have better resistance to stress and / or a different sugar metabolism are described. Compared to an unprocessed strain, they have a modification of at least one of their general glucose sensor systems composed of at least: a protein having a general glucose sensor function encoded by the GGS1 gene or a similar gene; a membrane affinity protein (permease) of low affinity glucose; a sugar kinase. n n n The modification of at least one of the GGS1 genes or of its alleles or of genes having, at least partially, the same function as this GGS1 gene, and / or of their promoter, and / or of their 3'-flanking sequence, confers to the transformed strain new properties for its production and / or its use as yeast for industrial use. |
