Three mutants of herpes simplex virus type 2: one lacking the genes US10, US11 and US12 and two in which Rs has been extended by 6 kb to 0.91 map units with loss of Us sequences between 0.94 and the Us/TRs junction.
In the process of generating restriction endonuclease site deletion mutants, we have isolated and characterized three mutants of herpes simplex virus type 2 (HSV-2), strain HG52, with large genomic deletions in Us and TRs. The deleted sequences (7.5 kb) extend from 0.94 map coordinates (m.c.) to 0.99 m.c. and are presumed to contain the HSV-2 gene… (More)
