Variability in gene expression is enhanced at the beginning of fermentation and during early stationary phase. Variability in gene expression was compared from T1 to T6 fermentation time points, considering the average deviation from the mean expression value as a measure of amplitude of gene expression. Panel A shows the distribution of the average deviation values for all strains and Panel B represents the same distribution for the environmental (06L3FF02, 06L6FF20) and commercial (AEB Fermol Rouge, Lalvin ICV D254 and Lalvin EC-1118) strains only. Inserts in Panels A and B expand the scale to highlight the frequency of highly variable genes.
