    Abstract:
    Factors including genetics, fertilization, and climatic conditions, can alter the biomass composition of soybean seeds, consequently impacting their market value and usage. This study specifically determined the content of protein and oil, as well as the composition of proteinogenic amino acids and fatty acids in seeds from 10 diverse soybean cultivars grown in four different sites. The results highlighted that different environments produce a different composition for the 10 cultivars under investigation. Specifically, the levels of oleic and linoleic acids, important contributors to oil stability, were negatively correlated. Although the protein and oil contents were higher in some locations, their "quality" was lower in terms of composition of essential amino acids and oleic acid, respectively. Finally, proteinogenic histidine and glutamate were the main contributors to the separation between Central and Northern growing sites. Taken together, these results can guide future breeding and engineering efforts aiming to develop specialized soybean lines.
