USE OF A VIRUS DNA AS PROMOTER

摘要

The invention relates to the characterization and use of powerful viral promoters for expressing genes in bacteria and fungi, especially yeasts. The invention is based on a surprising discovery, namely that CFDV-DNA (DNA of the coconut foliar decay virus) and fragments of CFDV-DNA contain a region active as promoter even in bacteria and fungi, especially yeasts, although they originate from a virus which infects monocotyledonous plants. The activity of these promoters in E. coli is markedly greater than that of the CaMV 35S promoter which is also active in bacteria.
