Manuscript in preparation.
The object of this manuscript is to make timetrees relating the
phiGT1 core structural proteins to a series of common ancestors
with other podoviral families over a time span leading back to the
origin of podoviruses, estimated to be > 3.2 Gya. This
generally required making alignments of the relevant protein
families covering a greater extent of divergence than is typically
attempted.
Although phiGT1 does not contain an RNA polymerase gene, the manuscript provided a control involving the T7-like RNA polymerase evolution
