  1. *1The relative levels of free mRNA and polysome-bound mRNA of selected genes were quantified by qRT-PCR in exponential phase ("exp") and stationary phase ("stat") cultures. The results for the 14 genes were normalized to the average values of six genes (upper part, OE2010R – OE4674R) which were presumed to be not translationally regulated based on the DNA microarray results. For comparison, the DNA microarray results are also listed. ORF numbers were taken from the genome website HaloLex [62]. The columns ∅, SD and n list average value, standard deviation and number of repetitions.
