Description Staining intensities of 10-kD and 13a polypeptide in seed storage protein are lower than those of the original cultivar. Rice storage proteins accumulate as two types of protein bodies in the starchy endosperm (Tanaka et al. 1980). Rice prolamine is stored in protein body type I (PB-I, spherical proteinaceous particles of lamellar structure). Rice glutelin is deposited in protein body type II (PB-II, a uniformly electron dense structure, 2-3 micron diameter). In SDS-PAGE analysis, PB-I has 10-kDa, 13a (a larger component of 13 kDa), 13b (a smaller component of 13 kDa) and 16-kDa polypeptides; and polypeptides of PB-II are 22-23 kDa, 26 kDa and 37-39 kDa.
