White lupin (Lupinus albus L.) is an annual crop cultivated for its protein-rich seeds. It is adapted to poor soils due to the production of cluster roots, which are made of dozens of determinate lateral roots that drastically improve soil exploration and nutrient acquisition (mostly phosphate). Using long-read sequencing technologies, we provide a high-quality genome sequence of a cultivated accession of white lupin (2n = 50, 451 Mb), as well as de novo assemblies of a landrace and a wild relative. We describe a modern accession displaying increased soil exploration capacity through early establishment of lateral and cluster roots. We also show how seed quality may have been impacted by domestication in term of protein profiles and alkaloid content. The availability of a high-quality genome assembly together with companion genomic and transcriptomic resources will enable the development of modern breeding strategies to increase and stabilize white lupin yield.

白羽扇豆的高质量基因组序列可提供对土壤勘探和种子质量的了解。
白羽扇豆（Lupinus albus L.）是一年生作物，其种子富含蛋白质。它因产生簇状根而适用于贫瘠的土壤，簇状根由数十种确定的侧根组成，可极大地改善土壤勘探和养分吸收（主要是磷酸盐）。使用长期阅读的测序技术，我们提供了白羽扇豆（2n = 50，451 Mb）的栽培种的高质量基因组序列，以及地方品种和野生近缘种的从头组装。我们描述了一种通过早期建立侧根和丛生根显示增加的土壤勘探能力的现代种质。我们还显示了驯化如何影响蛋白质质量和生物碱含量对种子质量的影响。
