Changes in the content of y-zein (Mr 27,000) in the endopserm of normal opaque-2, floury-2, and modifieed opaque-2 maize varieties known as quality protein maize (QPM) were evaluated using sodium dodecyl sulfate-polyacrylamide gel eletrophoresis, protein fractionation schemes, and an immunoabsorbance assay. QPM genotypes, which combine high levels of lysine and tryptophan with high yields, traditional appearance, and conventional kernel hardness, were shown to contain two to live times more y-zein than nornal, opaque-2, or floury-2 genotypes. Both soft and hard regions of QPM endosperm are enriched in y-zein; the latter show higher level of a a-zein. Relationships between amounts of zeins, kernel hardness, nutritional quality, and changes in other major protein components are discussed. |
