Synthetic hybrid tomato E4/E8 plant promoter

摘要

The present invention is directed to a synthetic hybrid promoter composed of polynucleotide segments derived from the E8 and E4 gene promoters. The hybrid promoter is capable of providing high-level expression of heterologous genes, particularly in transformed fruit. DNA constructs containing the E8-E4 hybrid promoter operably linked to an exemplary heterologous SAMase gene are effective in conferring a delayed ripening phenotype to transformed fruit.
