The <i>crtS</i> is conserved among Vibrionaceae.

<p>(<b>A</b>) Sequence alignment of <i>crtS</i> sites of 13 species within the Vibrionaceae, including <i>Vibrio</i>, <i>Aliivibrio</i> and <i>Photobacterium</i>. The alignment was done with Clustal Omega [<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1007251#pgen.1007251.ref067" target="_blank">67</a>] and MView [<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1007251#pgen.1007251.ref068" target="_blank">68</a>]. Blue highlights indicate sequence similarities, while orange rectangles the parts belonging to coding sequences of genes, black arrows start and end of the <i>crtS</i> as described [<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1007251#pgen.1007251.ref025" target="_blank">25</a>]. Green and purple arrows are for orientation in comparing subfigure A and B. (<b>B</b>) WebLogo of <i>crtS</i> from 114 species of Vibrionaceae published on NCBI. The heights of letters corresponds to their conservation within the group of sequences [<a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1007251#pgen.1007251.ref069" target="_blank">69</a>].
