Abstract excerpt
Sake yeast Kyokai no. 11 (K11) is an ethanol-tolerant mutant of Kyokai no. 7 (K7) and produces a higher ethanol concentration in the sake mash than K7. A previous study revealed that stress-induced genes under the control of STRE elements were upregulated in K11. To elucidate the causal mutation responsible for ethanol tolerance, we compared the genome sequences of the ethanol-tolerant mutants (K11 and K7AT2, a...
