Résumé
Promoters are key elements for the regulation of gene expression. Recently, we investigated the activity of promoters derived from marine diatom-infecting viruses (DIVs) in marine diatoms. Previously, we focused on potential promoter regions of the replication-associated protein gene and the capsid protein gene of the DIVs. In addition to these genes, two genes of unknown function (VP1 and VP4 genes) have been found in the DIV genomes. In this study, the promoter regions of the VP1 gene and VP4 gene derived from a Chaetoceros lorenzianus-infecting DNA virus (named ClP3 and ClP4, respectively) were newly isolated. ClP4 was found to be a constitutive promoter and displayed the highest activity. In particular, the 3' region of ClP4 (ClP4 3' region) showed a higher promoter activity than full-length ClP4. The ClP4 3' region might involve high-level promoter activity of ClP4. In addition, the ClP4 3' region may be useful for substance production and metabolic engineering of diatoms.
