There is provided synthetic nucleic acid fragments for the altered expressio n of selected nutritionally-important proteins in plants. These nucleic acid fragments may be used to transform plants, particularly crop plants, to increase the lysine and methionine content of seeds or leaves. The invention is of significant interest for the nutritional improvement of corn which is low in lysine and sulfur amino acid-poor plants, such as corn and soybean. Thre is also provided chimeric genes, host cells, plants, seeds and microorganisms containing the nucleic acid fragment as well as methods f or obtaining the expression of particular proteins in plants and microorganisms.
