FIG. 2.

Genome structure of SalHV-1. One of the two genome isomers is shown and is defined as the prototype. BamHI sites are marked, and fragment nomenclature is shown below in two ranks (A to Z and a to v). The inverted repeat (R_S) is shown in a wider format than nonreiterated regions (U_L and U_S). The locations of five cosmids are shown as rectangles below the fragment nomenclature, and BamHI sites are indicated. cos17 arose from a genome molecule in which U_S was inverted and thus appears to proceed from the right end of U_L, through R_S and into the right end of U_S, as indicated by the open ends of the rectangles.
