Abstract excerpt
Seed storage proteins are synthesized on rough endoplasmic reticulum (ER) as larger precursors and are sorted to protein storage vacuoles, where they are converted into the mature forms. We report here an Arabidopsis mutant, maigo 1 (mag1), which abnormally accumulates the precursors of two major storage proteins, 12S globulin and 2S albumin, in dry seeds. Electron microscopy revealed that mag1 seeds mis-sort...
