Abstract: The Benihoppe strawberry was treated with different concentrations of nordihydroguaiaretic acid (NDGA), which can depress the synthesis of abscisic acid (ABA) to investigate its influence on physiological indexes and related gene expression. The results showed that NDGA could significantly inhibit biosynthesis of soluble sugar and pelargonidin 3-O-glucoside chloride, and the inhibition became more obvious with the increasing concentration. In addition, FaNCED was inhibited and FaCYP707A, FaBG1 and FaCHLH were accelerated with a certain concentration of NDGA. Our study may provide helpful information for further study on molecular mechanism of NDGA on inhibiting the biosynthesis of ABA.
