Bluish color - the gene is in regulated operon. Different regulated operons are shown in different shades of blue.
Red color - the gene is in non-regulated operon.
Gray color - the orthologous gene is absent.
The star symbol - the TFBS is located in upstream region of this gene.
The number - the numeber of homologs (shown only if it is greater than one).
