Abstract

After cell infection with the equine herpesvirus 1 (EHV-1), the termini of the linear double-stranded DNA genome fuse to form circular forms. To investigate the mechanisms in the generation and cleavage of such replicative-form DNAs, the genomic termini, the fusion of termini from replicative-form molecules, and the junction between the short and long genome segments have been analyzed by restriction mapping, blot hybridizations, cloning, and sequencing. The data suggest that the genome ends are not redundant and that the genomic termini are fused in replicative intermediates via 3' single-base extensions at the termini of the unique long segment (UL) and terminal repeat (TR). Adjacent to the EHV-1 termini are AT and gamma sequence elements highly conserved among different herpesviruses. We propose that both of these sequence elements are important for the cleavage of EHV-1 replicative forms.
