Transcriptional enhancement by VLF-1 requires a burst sequence. (A) Transcription from the polyhedrin promoter in the presence and absence of a burst sequence. Transcripts were produced from in vitro transcription reaction mixtures containing pPolh/CFS and pPolhΔburst/CFS. Transcripts were quantified by using ImageQuant software and calculated as the ratio of pPolh/CFS to pPolhΔburst/CFS transcript. (B) Transcription from the chimeric p39kLburst/CFS template is stimulated by VLF-1. Reactions contained equimolar amounts of p39kL/CFS and pp39kLburst/CFS. Transcripts were quantified by using ImageQuant software.
