Abstract

Thisstudy explored a field-based approach to precisely characterizethe dynamics of the storage proteins (albumins and globulins fractions)biosynthesis and mineral nutrient accumulation (phosphorus, potassium,calcium, magnesium, sulfur, iron, boron, manganese, zinc, and copper)profile throughout the development of soybean seeds. Storage proteinbiosynthesis does not follow a linear progression from the beginningof seed filling (R-5.1) until the full maturity (R-8) stage, whereas it is accompanied by sulfur and magnesium demandpeaks. Globulin concentration was consistently higher than the albuminsat all developmental stages and reached an accumulation peak in theR(6) stage. These results depict an intricate associationbetween sulfur and magnesium concentration and the biosynthesis ofstorage proteins in soybean seeds. (AU)
