具有高油、高蛋白特点的大豆(Glycine max(L.)Merr)是世界上主要农作物之一,广泛用作人类的食物、动物的饲料和生物能源。2010年1月,大豆基因组测序完成并公布,使得大豆基因组研究有了突飞猛进的发展。大豆基因组大小约1.1Gb,基因组测序覆盖率达85%以上,依赖于基因组数据,共从中预测出46,430个高置信蛋白质编码基因,其中12.2%为转录因子基因,且78%的基因具有多个拷贝,由此推断其分别在5,900万年和1,300万年前经历了两次大规模的复制和重组。
Glycine max (L.) Merr, a high-oil, high-protein soybean that is widely used as a human food, animal feed and bioenergy, is one of the world’s major crops. In January 2010, the sequencing of soybean genome was completed and released, which made the research on soybean genome advance by leaps and bounds. With a genome size of about 1.1Gb and genome coverage of more than 85%, 46,430 high-confidence protein-coding genes were predicted from genomic data, of which 12.2% were transcription factor genes and 78% had multiple copies , Concluding that it has undergone two large-scale duplications and reorganizations 59 million years and 13 million years ago respectively.
