KEY MESSAGE : We showed that rice prolamin polypeptides formed ER-derived PBs in transgenic rice calli, and that this heterologous transgene expression system is suitable for studying the mechanism of rice PB-I formation. Rice prolamins, alcohol-soluble seed storage proteins, accumulate directly within the rough endoplasmic reticulum (ER) lumen, leading to ...
