Core Insights - The article discusses the domestication, dissemination, and improvement trajectories of soybean, highlighting its significance as a major source of protein and oil for human consumption and animal feed [3][4][6]. Group 1: Research Findings - The study analyzed genomic information from 8,105 soybean accessions, including wild types, local varieties, and modern cultivars, revealing the genetic selection trajectories during domestication and improvement [4][6]. - Black soybean is identified as a key intermediate type in the domestication process, with findings suggesting that domestication traits were selected gradually [6][7]. - The research proposes the existence of two independent centers of soybean domestication in China: one in the Huang-Huai-Hai region and another in the northwest [6][7]. Group 2: Implications for Breeding - The study provides new molecular targets for future soybean quality improvement by identifying selected genes that facilitated trait enhancement and environmental adaptation during global dissemination [6][9]. - It highlights the shift in breeding focus in China from high-protein soybean varieties in the early years to an emphasis on high yield, high oil content, and stress resistance in recent years [6][9]. - A high-density soybean genome variation map and quantitative trait nucleotide (QTN) database were established, providing valuable resources for the global research community [7][9].
