23 Jul Paddy endosperm specific expression promoter pOsPYL8
Abstract
The invention relates to a paddy endosperm specific expression promoter pOsPYL8 and provides the promoter of the upstream sequence of a receptor protein gene (OsPYL8) of paddy abscisic acid (ABA), and the promoter is named as the pOsPYL8 promoter. According to the paddy endosperm specific expression promoter pOsPYL8, through expression profiles analysis conducted on different paddy tissue positions and reporter gene expression analysis conducted on transgenic plants, it is verified that the pOsPYL8 promoter can specifically drive expression of a target gene in paddy endosperm tissues. The pOsPYL8 promoter can be applied to genetic engineering improved rice endosperm relative characters and expression of recombinant protein in endosperm.
