%X The effects of sulfur deficiency on the synthesis and accumulation of polypeptides in the developing wheat grain between 6 and 36 days after anthesis were examined by sodium dodecyl sul- fate-polyacrylamide gel electrophoresis. Wheat grain proteins were divided into two groups based on their solubility characteristics: (a) salt-soluble, and (b) salt-insoluble. Sulfur deficiency resulted in changes in the synthesis and accumulation of both groups of polypeptides, but the changes were more pronounced in the salt-insoluble group. In neither case were the changes as dramatic as those reported previously for sulfur deficient legume and barley seeds. In sulfur-deficient wheat plants, storage protein synthesis in developing seeds was detectable earlier than in plants grown with adequate sulfur.
