Figure 3. Multiple genome alignment performed using Mauve software (http://asap.ahabs.wisc.edu/mauve/) and the chromosomes of related phages.

Similarity is represented by the height of the bars, which correspond to the average level of conservation in that region of the genome sequence. Completely white regions represent fragments that were not aligned or contained sequence elements specific to a particular genome. Boxes with identical colours represent local collinear blocks (LCB), indicating homologous DNA regions shared by two or more chromosomes without sequence rearrangements. LCBs indicated below the horizontal black line represent the reverse complements of the reference LCB.
