The expression of aromatic compound synthesis genes is highly variable. Highly variable genes were identified at several fermentation stages, with particular incidence for genes required for the production of fusel alcohols and other aromatic compounds. Examples of this were ARO9 and ARO10 genes whose products are part of the Ehrlich pathway, CYS3 and several MET genes involved in the production of sulphur containing volatile compounds and EXG2, which is required for the production of volatile glycosides. Their relative transcript levels and those of other highly variable genes is shown.
