Abstract

Modern crops were created through the domestication and genetic introgression of wild relatives and adaptive differentiation in new environments. Identifying the domestication-related genes and unveiling their molecular diversity provide clues for understanding how the domesticated variants were selected by ancient people, elucidating how and where these crops were domesticated. Molecular genetics and genomics have explored some domestication-related genes in soybean (Glycine max). Here, we summarize recent studies about the quantitative trait locus (QTL) and genes involved in the domestication traits, introduce the functions of these genes, clarify which alleles of domesticated genes were selected during domestication. A deeper understanding of soybean domestication could help to break the bottleneck of modern breeding by highlighting unused genetic diversity not selected in the original domestication process, as well as highlighting promising new avenues for the identification and research of important agronomic traits among different crop species.

大豆驯化关键基因的遗传基础研究进展

现代作物是通过野生亲缘植物的驯化和基因渗入以及在新环境中的适应性分化而产生的。识别驯化相关基因并揭示其分子多样性，为了解古代人是如何选择驯化变体的，阐明这些作物是如何以及在哪里驯化的提供了线索。分子遗传学和基因组学对大豆驯化相关基因进行了探索。在这里，我们总结了近年来关于数量性状基因座（QTL）和参与驯化性状的基因的研究，介绍了这些基因的功能，阐明了在驯化过程中选择了哪些驯化基因的等位基因。更深入地了解大豆驯化有助于打破现代育种的瓶颈，突出在原始驯化过程中没有选择的未使用的遗传多样性，并突出在不同作物物种之间鉴定和研究重要农艺性状的有前景的新途径。
