Overview of Research on Soybean Maturity Genes E1~E4
The E gene family in soybean plays an important role in regulating its maturity,therefore,identifying the E gene variation types of different soybean varieties is of great value for predicting the maturity of soybean parents and offspring in advance.With the con-tinuous development of molecular biology technology,numerous members of the soybean E gene family have been identified.Especially E1 to E4,as the main effector genes,multiple types of variation have been discovered and identified one after another.This article pro-vides an overview of the characteristics of E1 to E4 genes,their different genotypes,and their relationship with maturity.It also provides prospects for efficient prediction and genetic improvement of soybean maturity in the future.
