Abstract
Studies on the Marek's disease virus (MDV) serotype 2 (MDV2) genome may be important for understanding the naturally nononcogenic nature of the virus. To determine the complete DNA sequence of MDV2 unique short (U(s)) region, genomic BamHI fragments F, M1 and R were sequenced. The MDV2 U(s) region is 12 109 bp long and contains 12 potential open reading frames (ORFs) likely to encode for proteins. Seven of them exhibit homologies to herpes simplex virus type 1 (HSV-1) US1 (ICP22), US2, US3 (protein kinase), US6 (gD), US7 (gI), US8 (gE) and US10 genes. These ORFs are conserved in a similar arrangement with those of HSV-1, except for US10 which is transposed in the U(s) regions of all three MDV serotypes. The predicted amino acid sequence of MDV2 ORF6 is homologous to SORF3 of the other serotypes of MDV serotype 1 (MDV1) and herpesvirus of turkeys (HVT) and to infectious laryngotracheitis virus SR1. In addition, four ORFs, which have been identified around the U(s) and inverted repeat junction regions, have no apparent relation to any other known herpesvirus genes. The identified ORFs in the MDV2 U(s) region were more colinear with their previously reported locations of MDV1 than with those of HVT and other alphaherpesviruses. Ten of the 12 ORFs in the MDV2 U(s) region were expressed and transcribed with 3'-coterminal transcripts and/or a unique transcript in the virus-infected cells. Compared to other MDV serotypes, the MDV2 U(s)-encoded proteins showed 46-70% and 33-59% identities with equivalent of MDV1 and HVT at the amino acid level, respectively. Our present data will be useful to understand the different pathogenicity among serotypes of MDV and to allow precise manipulation of the genes for a possible use in genetically engineered vaccines.
