Use of tomato e8-derived promoters to express heterologous genes, e.g. s-adenosylmethionine hydrolase, in ripening fruit

摘要

The use of AdoMetase to reduce ethylene biosynthesis in plants is facilitated by the exploitation of the tissue and stage specific properties of the E8 promoter from tomato. Expression of AdoMetase is shown to be limited to the ripening tomato fruit. The functional properties of several regions of the E8 promoter are also described. The E8 promoter, and variants described herein, provides a useful regulatable promoter for the expression of other genes as well as the AdoMetase gene.
