An endosperm derived tissue culture of maize (Zea mays L.) variety A636 has been characterised for its ability to synthesize zein protein and respond to a zein gene regulatory element. Western analysis with zein specific antibodies revealed the distinct presence of zein proteins of the 15, 19 and 21
Zeins, the major endosperm proteins in maize (Zea mays L.), are deficient in the essential amino acids lysine and tryptophan. Some mutant genes, like opaque-2 (o2) and floury-2 (fl2), reduce the levels of A- and B-zeins, thereby improving maize's nutritional value. Other mutants, such as amylose-ext
