Comparison of Expression Activity of Key Genes in Strawberry Fruit Development

Abstract

Key genes in strawberry fruit development play an important role in the development and maturation of strawberry fruit, and are also important in molecular breeding and genetic improvement. UPL probes was used to quantitatively analyze the expression of strawberry genes FaNCED1 , FaPG , FaEXP5 and FaDFR at different stages of fruit development and in different organs. The results showed that FaPG and FaEXP5 significantly increased expression in the late stage of fruit development. And FaPG had significant fruit-specific expression. At every stage of fruit development, FaDFR showed a higher level of expression than other genes. This study provides some theoretical reference for the development and utilization of key genes in strawberry fruit development.
