Abstract
Provided is a modified rice endosperm-specific promoter, which has a sequence as shown in any one of SEQ ID. NOs. 1 to 5. The EnhGt13a promoter as shown in SEQ ID NO. 2 drives GUS activity in vitro and mediates the expression of foreign proteins in rice endosperm cells, which is significantly higher than that of the unmodified Gt13a promoter. The promoter can be applied to the fields of improving seed quality, molecular pharming, etc.
