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, 451Mb), 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. White lupin is an annual crop cultivated for protein rich seeds and can produce cluster roots for efficient phosphate acquisition. Here, the authors generate high quality genome assemblies of a cultivated accession, a landrace, and a wild relative and provides insight into soil exploration and seed quality. specialized 076 020 11 1 art. 492 [12 p.] 2020 2041-1723 https://www.documentation.ird.fr/hor/fdi:010079158 10.1038/s41467-019-14197-9 2041-1723 [F B010079158] https://www.documentation.ird.fr/hor/fdi:010079158 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers20-07/010079158.pdf IRD - Base Horizon / Pleins textes 2020-07-31 2025-02-24 fdi:010079158 fre
