Effects of Exogenous Calcium on Activity of Fructokinase and Gene Expression in Tomato Fruits

摘要：

Sugar contents, related enzymes activities of sucrose metabolism, activity and gene expression of fructokinase(FRK) were studied during tomato fruit development by calcium treatment. The results showed that the gene expression of fructokinase ascended firstly then descended, and fell to the lowest at mature period of fruit during fruit development. And the FRK1 gene expression was higher than FRK2. After exogenous calcium treatment, the FRK1 gene expression was accelerated at the early stage of fruit development, activity of fructokinase was decreased during the middle stage, but the activity of acid invertase was increased during mature period of fruit, and the contents of fructose and glucose were increased during mature period of fruit.
