Abstract excerpt
Rice (Oryza sativa) glutelins are synthesized on the endoplasmic reticulum as larger precursors, which are then transported via the Golgi to the protein storage vacuole (PSV), where they are processed into acidic and basic subunits. Three independent glutelin precursor mutant4 (glup4) rice lines, which accumulated elevated levels of proglutelin over the wild type, were identified as loss-of-function mutants of...
