【摘要】：自2010年大豆(Glycine max)基因组论文在Nature杂志上正式发表以来,以中国为主的多国科学家已对众多不同地理来源的野生大豆、农家品种及栽培品种进行了基因组重测序,并通过比较基因组学等技术手段,揭示了大豆基因组在进化与驯化过程中的基本规律。利用大豆基因组信息,科学家已成功克隆了调控大豆生育期、生长(结荚)习性、种子形态性状与组分、结瘤与养分利用效率、生物及非生物胁迫抗(耐)性等重要农艺性状的功能基因,并初步揭示了其相关的作用机理,取得了一系列突破性进展,为今后进一步精细解析大豆基因组与相关性状的基因调控网络奠定了坚实的基础,同时为通过分子(模块)设计育种来培育新品种创造了必要条件。
[Abstract]:Since 2010, when the genome paper of Glycine maxis was published in the journal Nature, scientists from many countries, mainly from China, have studied many wild soybeans from different geographical sources. The genome resequencing of farm and cultivated varieties was carried out, and the basic rules of soybean genome in evolution and domestication were revealed by comparative genomics and other techniques. The information of soybean genome was used. Scientists have successfully cloned and regulated soybean growth, growth (pod) habits, seed morphological traits and components, nodulation and nutrient use efficiency. The functional genes of important agronomic traits such as biotic and abiotic stress resistance (tolerance) and its related mechanism have been preliminarily revealed and a series of breakthrough progress has been made. It lays a solid foundation for further fine analysis of gene regulation network of soybean genome and related traits, and creates the necessary conditions for breeding new varieties by molecular (modular) design.
