NEW MATERIAL:DNA corresponding to 290-90 of 35S promoter or DNA containing plural number of the said DNA arranged putting a spacer between them or without putting the spacer. USE:For example, formation of high-activity manifesting vector. PREPARATION:A desired 35-S promoter region is cut out from a plasmid containing Cauliflower mosaic virus (CaMV) 35S promoter using a suitable restriction enzyme in a fragment state. The resultant promoter region fragment is then recombined in a host vector system for control of the plasmid, thus obtaining the objective gene control sequence region. |
