文摘
- •
The mutation in OsAGPL2 resulted in aberrant storage substances in the w24 endosperm.
- •
Expression of AGPase, activities of Pho1 and SuSy were enhanced in the w24 endosperm.
- •
Expression of OsAGPL2 and OsAGPS2b was highly coordinated in rice endosperm.
- •
Direct interactions of OsAGPL1:OsAGPS1 as well as OsAGPS2b:OsAGPL2 were verified.
- •
Self-binding was evident for the OsAGPL2 subunits but not the OsAGPS2b subunits.
