Efeito diferencial do gene opaco-2 sobre os níveis de aminoácidos proteicos e livres nas diferentes partes do grão de milho durante o seu desenvolvimento
Palavras-chave:
composição aminoacídica, fração protéica, gene opacoResumo
The effects of opaque-2 gene on the levels of free and protein amino acids in the upper and lower halves of endosperm and in the germ, during grain deve- lopment, were studied by using the normal and opaque-2 versions of corn line 869.
