Glycine max strain:Williams 82 RefSeq Genome. Glycine max strain:Williams 82

Glycine max, is an annual herb of great economic importance. It belongs to family Fabaceae and tribe Phaseoleae which includes several other important legumes like beans, pigeon pea, black gram, mung bean etc. It is believed to have originated in Asia but is now cultivated extensively for food and forage throughout the world. It is a major source of vegetable oil and protein in the world. Each soybean seed contains about 20% oil and about 50% of the remaining meal is protein. The genome of G. max is a diploidized tetraploid with 2n = 40 chromosomes and a genome size of about 1115 Mb. The large genome has hampered the genome sequencing efforts in soybean though several well developed genomic resources are available. It has a well developed composite genetic map. Large number of ESTs and a number of BAC libraries are also available. NSF has recently announced the funding of Soybean Genome sequencing project. Scott Jackson of Purdue University will lead the project. DOE-JGI has announced that they have accepted soybean for a WGS endeavor.

大豆（Glycine max）是一种具有重大经济价值的一年生草本植物。它隶属于豆科（Fabaceae）菜豆族（Phaseoleae），该族还涵盖菜豆、木豆、黑吉豆、绿豆等多种其他重要豆科作物。学界普遍认为其起源于亚洲，如今已在全球范围内广泛种植，用作粮食与饲草。它是全球重要的植物油与植物蛋白来源。每粒大豆种子约含20%的油脂，脱油后的粕中约有50%为蛋白质。大豆的基因组为二倍体化的四倍体，染色体数为2n=40，基因组大小约为1115 Mb。尽管目前已具备多项成熟的基因组学资源，但庞大的基因组仍阻碍了大豆的基因组测序工作。其拥有完善的整合遗传图谱。此外，还拥有大量表达序列标签（EST）与多套细菌人工染色体（BAC）文库。美国国家科学基金会（NSF）近日宣布将资助大豆基因组测序项目，该项目由普渡大学的斯科特·杰克逊（Scott Jackson）牵头。美国能源部联合基因组研究所（DOE-JGI）已宣布将把大豆纳入全基因组测序（WGS）工作范畴。
