Production of nerolidol by mutant strains deleted for PDR8 targets, reported relative to the production by the wild-type strain By4741. The Dunnett test was used to compare the production by each deletant strain to that by the corresponding wild type strain (p-value <0.05). Each experiment was repeated at least twice. For By4742 ΔERG20/wt and BY4742 ΔERG8/wt the wild-type control strain is By4743. Bars in gray indicate that the production was not significantly different to that by the wt. White bars indicate that the production of nerolidol was significantly different from that by wt.
