Resumo
This study explored a field-based approach to precisely characterize the 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 protein biosynthesis does not follow a linear progression from the beginning of seed filling (R5.1) until the full maturity (R8) stage, whereas it is accompanied by sulfur and magnesium demand peaks. Globulin concentration was consistently higher than the albumins at all developmental stages and reached an accumulation peak in the R6 stage. These results depict an intricate association between sulfur and magnesium concentration and the biosynthesis of storage proteins in soybean seeds.
