A minimal peach type II chlorophyll a/b-binding protein promoter retains tissue-specificity and light regulation in tomato

摘要

BackgroundPromoters with tissue-specificity are desirable to drive expression of transgenes in crops to avoid accumulation of foreign proteins in edible tissues/organs. Several photosynthetic promoters have been shown to be strong regulators of expression of transgenes in light-responsive tissues and would be good candidates for leaf and immature fruit tissue-specificity, if expression in the mature fruit were minimized.
