Genome synteny alignments of <i>Ca</i>. N. evergladensis, (A) <i>Ca</i>. N. gargensis and (B) <i>N. maritimus</i>.

<p>Axes X and Y represent topology of coding sequences in the comparing genomes. Entire genomes were compared by MUMmer 3.0 package using Promer tool <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0101648#pone.0101648-Kurtz1" target="_blank">[114]</a>. Each dot represents a match of at least six amino acids from compared genomes. Forward matching amino acid sequences are plotted as red lines/dots while reverse are plotted as blue lines/dots. A line of dots with slope = 1 represents an undisturbed segment of conservation between the two sequences, while a line of slope = −1 represents an inverted segment of conservation between the two sequences.
