A reference assembly for the legume cover crop, hairy vetch (Vicia villosa)

Abstract

ABSTRACTVicia villosais an incompletely domesticated annual legume of the Fabaceae family native to Europe and Western Asia.V. villosais widely used as a cover crop and as a forage due to its ability to withstand harsh winters. A reference-quality genome assembly (Vvill1.0) was prepared from low error rate long sequence reads to improve genetic-based trait selection of this species. The Vvill1.0 assembly includes seven scaffolds corresponding to the seven estimated linkage groups and comprising approximately 68% of the total genome size of 2.03 gigabase pairs (Gbp). This assembly is expected to be a useful resource for genetic improvement of this emerging cover crop species as well as to provide useful insights into plant genome evolution.
