Duck enteritis virus (DEV) UL49.5 encoding glycoprotein N was a conserved gene. The transcription dynamic process of UL49.5 homologous genes in herpesviruses was reported. However, the transcription dynamic process of DEV UL49.5 gene has not yet been established. In this study, a real-time quantitative reverse transcription PCR (real-time qRT-PCR) assay was established to test the transcription dynamic process of DEV UL49.5 gene, and the recombinant plasmid pUCm-T/UL49.5 was constructed as the standard DNA. The samples prepared from DEV-infected (at different time points) and uninfected cell were detected and calculated. The results demonstrated that the real-time qRT-PCR assay was successfully established. The transcription product of DEV UL49.5 gene was first detected at 0.5 h post infection (p.i.), increased at 8 h p.i. and reached a peak at 60 h p.i. Our results illustrated that DEV UL49.5 gene could be regarded as a late gene. The transcription dynamic process of DEV UL49.5 gene may provide a significant clue for further studies of DEV UL49.5 gene.
