Results of the RT-qPCR assay of highly duplicated transposase ORFs. All values indicate relative fold increase of transcription between samples standardized against glnA transcript levels. Panel A - fold changes of transcripts between five day and three day time points of cultures grown on N2 (black bars) or NH4 (gray bars). Panel B: fold changes of 5dN2 vs 3dNH4. Panel C: fold changes of 3dN2 vs 5dNH4 transposase ORFs respectively. The table (inset) indicates the copy number of duplicated transposase ORFs within each IS group as well as the locus tag of one of the representative members of that group. Error bars indicate standard error of triplicate reactions over each histogram.
