Grass pea (Lathyrus sativus) is a cool-season legume crop tolerant to drought, salinity, waterlogging, insects, and other biotic stresses. Despite these beneficial traits, this crop is not cultivated widely due to the accumulation of a neurotoxin - β-N-oxalyl-L-α, β-diaminopropionic acid (β-ODAP) in the seeds and its association with neurolathyrism. In this study, we sequenced and assembled the genome of Lathyrus sativus cultivar Pusa-24, an elite Indian cultivar extensively used in breeding programs. The assembled genome of Lathyrus was 3.80 Gb in length, with a scaffold N50 of 421.39 Mb. BUSCO assessment indicated that 98.3% of highly conserved Viridiplantae genes were present in the assembly. A total of 3.17 Gb (83.31%) of repetitive sequences and 50,106 protein-coding genes were identified in the Lathyrus assembly. The Lathyrus genome assembly reported here thus provides a much-needed and robust foundation for various genetic and genomic studies in this vital legume crop.
兵豆（Lathyrus sativus）是一种耐干旱、耐盐、耐涝、抗虫等生物胁迫的冷季豆科作物。尽管具有这些有益的特性，但由于种子中积累了一种神经毒素——β-N-草酰-L-α、β-二氨基丙酸（β-ODAP），以及它与 neurolathyrism 的关联，这种作物并没有广泛种植。在这项研究中，我们对 Lathyrus sativus 栽培品种 Pusa-24 的基因组进行了测序和组装，该品种是印度广泛用于育种计划的一种优良品种。组装的 Lathyrus 基因组长 3.80Gb，支架 N50 为 421.39Mb。BUSCO 评估表明，高度保守的 Viridiplantae 基因中有 98.3%存在于该组装中。在 Lathyrus 组装中总共鉴定出 3.17Gb（83.31%）的重复序列和 50106 个蛋白质编码基因。因此，这里报道的兵豆基因组组装为这个重要的豆科作物的各种遗传和基因组研究提供了急需的强大基础。
