Chemical screening methods for maize protein quality at CIMMYT
(CIMMYT, 1971)
In 1964 Mertz, Bates and Nelson ( 1) found that the mutant gene opaque-2 of maize produces a modified amino acid balance of the grain endosperm protein with increased quantities of lysine and tryptophan. This discovery ...
