| Popis: | We constructed a self-cloning diploid baker's yeast strain that overexpressed the transcription activator Msn2. It showed higher tolerance to freeze-thaw stress and higher intracellular trehalose level than observed in the wild-type strain. Overexpression of Msn2 also enhanced the fermentation ability of baker's yeast cells in frozen dough. Hence, Msn2-overexpressing baker's yeast should be useful in frozen-dough baking. |
