Zeins, the major endosperm proteins of maize, represent about 50% of total seed proteins and consist of several alcohol-soluble polypeptides encoded by at least four families of genes. The accumulation of zeins is under the control of several broadly defined regulatory genes. One of these, the opaque-2 mutant, lowers the level of zeins, thus improving the nutritional quality of maize meals. We demonstrate here that a salt-soluble protein of molecular weight 32,000 (b-32) is under control of O2… CONTINUE READING
