Dotplot of the genomes of M. fermentans strains M64 versus JER (A) and PG18 (B).

<p>The graphs were generated with the <i>Gepard</i> 1.21 with word length of 20 and window size of 0 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0032940#pone.0032940-Krumsiek1" target="_blank">[78]</a>. The long repetitive sequences are indicated by horizontal arrows: ICEF-I and -II (unfilled arrows), ICEF-III (black arrows), and ΦMFV1 (gray arrows). The locations of the IS elements of the ISMf<i>1</i>, IS<i>1550</i> and IS<i>1630</i> families are indicated by small black and gray (elements interrupted by ICEFs) triangles. The two types of non-IS small duplications are indicated by small filled (16–23S rRNA operon) and open triangles (uncharacterized repetitive sequence containing a hypothetical protein-coding gene).
