The figure below was created by taking the gene tracks
from Bio::Graphics and marking them up
with a paint program. Only the 80 Kb region where
StaphK parallels phageD is shown. The confinement of this pattern
to just part of phageD indicates some large scale modular reassortment
between these two phages. Within the region, there is obviously a
substantially similarly organized common ancestor as of 0.5 Bya.
However, there are smaller scale indels (insertions or deletions) in evidence
at many places. Some of the apparent mosaicism is false as discussed
in the next section.
Black marks indicate relationships obvious in a general
Blast search, and red marks generally indicate where something more had
to be done to find or clarifiy the relationship.
PhageD is on top; Staph. phage K is on the bottom.
