Gallid herpesvirus 1 (infectious laryngotracheitis virus): cloning and physical maps of the SA-2 strain

Abstract
Clones representing 90% of the genome of Gallid herpesvirus 1 (infectious laryngotracheitis virus; ILTV) were obtained and used in hybridization experiments to constructEcoRI,KpnI amdSmaI physical maps. The genome was 155 kilobase pairs (kbp) and comprised of a long unique sequence (120 kbp) and a short unique sequence (17 kbp) bounded by repeat sequences each of 9 kbp. An unrelated second pair of repeat sequences was located at 0.67 and 0.88 map untis. A terminal repeat of the unique long region (UL) was also detected, but no isomerization of UL was detected.
