A: Production of nerolidol by two hemizygote strains carrying only the 59A or the S288C - PDR8 allele. Dark gray: S288C, Light Gray: 59A. Differences are highly significant (p value<0.001). For each experiment, three fermentations were performed as described for experiment B. B: Production of nerolidol by the different segregants, relative to that measured for the parental strains indicated as 59A and S288C. (Data from experiment A). Segregants carrying 59A allele of PDR8 are indicated as Seg 59A, and segregants carrying S288C allele of PDR8 are indicated as Seg S288C.
