Rice plants are supplied at the beginning of the shooting with (N^<15>H_4)_2SO_4 and various parts of brown rice, that is, the embryo, the bran and the proteins of the endosperm, are isolated and analyzed for their isotope concentration. In all parts, the N^<15> concentration of the embryo is the highest, and next come that of globulin, oryzenin and insoluble protein in the endosperm. Next in order of decreasing N^<15> concentration comes the bran. And finally, it should be emhasized that N^<15> concentration of prolamine and albumin in the endosperm are lower than that of any other parts. Whether the differences in the isotope concentration of various parts indicate the relative physiological importance of the respective parts or not, and also whether those differences are influenced by the mechanism of maturing process or not must be regarded as open questions.
