Evaluation of the predictions of LexA-binding sites in the 26 cyanobacterial genomes. The green curves represent the probability $p(S_{I_U}>s)$ and the blue curves $p(S_{C_U}>s)$. The cyan curves are the number of iner-TU regions containing a putative binding site with a score > s, $N(S_{I_U}>s)$. The red curves are the log-odds ratio (LOR), defined as $LOR(s)=\ln (p(S_{I_U}>s)/p(S_{C_U}>s))$, (see Methods). Refer to Abbreviation for the full name of each genome.
