Glycoprotein D (gD) and glycoprotein I (gI) genes of bovine herpes virus 1 (BHV1) are contiguous genes with 141 bp region between the two open reading frames (ORFs). Expression of gD and gI from a bicistronic construct containing complete gD and gI gene has been reported either through internal ribosome entry site (IRES)-like element or through the scanning and leakage model (Mukhopadhyay 2000). We here show by computational and experimental means that gD is expressed solely as bicistronic transcript comprising gD and gI coding region in BHV1-infected cells. gI ORF was also shown to express separately. An IRES-like element was also predicted by IRES predicting software in the middle of the gD coding region; within that region a putative promoter was also identified by promoterscan. The intergenic region between the two ORF showed extensive secondary structure which brings the stop codon of gD very close to start codon of gI gene. gD gene transcript in BHV1-infected cells was solely bicistronic. gI transcript was also present in the BHV1-infected cells but in low copy number. The results indicate that gI is probably transcribed from its own transcript in BHV1-infected cells.
