Schematic of isomeric forms of the LHV-4 genome and location of the DNA probes used in hybridization. UL and US indicates the long and short unique regions, respectively. The solid arrow represents the RL, the open arrow represents the RS. The “a” sequence is the boundary between RL and RS. Locations of DNA probes are shown in striped boxes (UL1, UL56, ICP0, ICP4, and US1) above the maps and are drawn in an approximate scale with respect to their genome locations. A and B) Two possible EcoR I sites near the end of the genome containing RL and RS. The EcoRIa and b sites are near UL1 and UL56, respectively. C and D) Two possible BamHI sites near the end of RL. The BamHI a and b sites are near UL1and UL56, respectively.
