Fig. 3From: Effect of overexpression of SNF1 on the transcriptional and metabolic landscape of baker’s yeast under freezing stressAnalysis of freezing tolerance. The cells were cultivated in the LSMLD medium at − 20 °C for 7 days. ABY3: the parental strain; ABY+YP: the strain carrying the vector Yep-PK used as a blank control to demonstrate any possible effect of the empty vector; ABY+S: the transformant carrying SNF1 overexpression. Significant differences among the three strains (ABY3, ABY+YP, and ABY+S) were confirmed at *p < 0.05Back to article page
