title: [Free and bound amino acids during germination of maize seeds with implemented foreign prolamines].
abstract: Wheat prolamines were preincorporated into the endosperm of maize seed, and concentrations of free and bound amino acids were measured in the endosperm and seedlings during seed germination. Incorporation of foreign prolamines lowered the decrease rate of free proline concentration in both the endosperm (sprouting and shoots) and the embryo (sprouting). The seedlings at the stage of shoots were characterized by higher concentrations of aspartic acid, glutamic acid, and tyrosine. At the stage of transition to autotrophic nutrition, the pool of amino acids that are physiologically important for the plant growth was greater in maize seedlings with incorporated wheat prolamines.
