| contents | A Reference Assembly for the Legume Cover Crop Smooth Vetch Roth var. . Yao, Zhongxu Li, Xinru Wang, Yurou Sun, Yaqi Lu, Songchong Su, Kunlong Zhang, Huajie Yang, Shaoyong Yang, Guofeng Ma, Lichao Roth var. (smooth vetch) is an economically important legume cover crop valued for its nitrogen-fixing capacity, high biomass yield, and adaptability across diverse agroecosystems. Here, we present a chromosome-scale, high-quality genome assembly of var. , constructed using PacBio HiFi sequencing combined with Hi-C scaffolding. The assembly spans 3.70 Gb with a scaffold N50 of 4.69 Mb and exhibits lower heterozygosity (0.9%) compared to Roth (3.1%). Genome analysis revealed significant expansion of long terminal repeat retrotransposons (LTR-RTs), as well as lineage-specific proliferation of miniature inverted-repeat transposable elements (MITEs) in var. Comparative genomics with Roth highlighted gene family expansions associated with trichome development, providing insights into the genetic basis of morphological and adaptive differences within the species. This reference genome provides a foundational resource for accelerating the breeding of varieties with enhanced agronomic traits and contributes to a broader understanding of legume genomics and plant genome evolution. |
