Abstract

Grasspea (Lathyrus sativus L.) is an underutilised but promising legume crop with tolerance to a wide range of abiotic and biotic stress factors, and potential for climate-resilient agriculture. Despite a long history and wide geographical distribution of cultivation, only limited breeding resources are available. This paper reports a 5.96 Gbp genome assembly of grasspea genotype LS007, of which 5.03 Gbp is scaffolded into 7 pseudo-chromosomes. The assembly has a BUSCO completeness score of 99.1% and is annotated with 31719 gene models and repeat elements. This represents the most contiguous and accurate assembly of the grasspea genome to date.

摘要

兵豆（Lathyrus sativus L.）是一种未充分利用但有前景的豆科作物，对多种非生物和生物胁迫因素具有耐受性，并且具有适应气候变化的农业潜力。尽管兵豆的栽培历史悠久，分布范围广泛，但可用的育种资源却很有限。本文报道了兵豆 LS007 基因型的 5.96 Gbp 基因组组装结果，其中 5.03 Gbp 被组装到 7 个假染色体中。该组装的 BUSCO 完整性评分为 99.1%，并注释了 31719 个基因模型和重复元件。这是迄今为止兵豆基因组最连续和准确的组装。
