Fig. 4

Scatter plot of mean expression values of clustered and non-clustered genes in different functional groups during growth on a d-glucose (filled circles) and lactose (open circles) and b glycerol. Dotted lines indicate linear trend lines. Mean expression values were calculated from the log hybridization intensity (for d-glucose and lactose) or RPKM (kilobase of exon per million mapped sequence reads) for glycerol. Standard deviations for the mean values were all <28 %
