Highly abundant <i>cis</i>-regulatory elements.

<p>Nucleotide conservation of the five (A-E) highly abundant <i>cis</i>-regulatory motifs is displayed as sequence logos. The location of the motif in relation to the TLS is indicated by bar charts (bin size 50 nt). The frequency of the motif per bin was weighted according to the underlying length distribution of the upstream regions.
