Abstract excerpt
Soybean serves as a critical source of plant-based protein for both livestock and human nutrition, making seed protein content a key agronomic trait. However, modern soybean cultivars exhibit reduced seed protein content compared to their wild relatives, as a consequence of domestication and historical selection that favored yield over nutritional quality. Thus, genetic improvement of seed protein is highly...
