A synthetic plant core promoter

摘要

A synthetic DNA plant promoter sequence comprising a TATA motif; a transcription start site and a region between the TATA motif and the start site that is at least 64% GC-rich is claimed. Also claimed is an expression cassette comprising a synthetic promoter comprising a TATA motif; a transcription start site and a region between the TATA motif and the start site that is at least 64% GC-rich; a structural gene operatively linked to the promoter and a transcription end site polyadenylation signal. A vector comprising the promoter described above and a transgenic plant transformed by the vector are also claimed.
