Graph-based pan-genome reveals structural and sequence variations related to agronomic traits and domestication in cucumber

H. Li, S. Wang, et al.

Discover the groundbreaking research on cucumber genetics, where a comprehensive pan-genome has unveiled approximately 4.3 million genetic variants, including over 56,000 structural variants linked to key agronomic traits. This innovative work by Hongbo Li and colleagues enhances our grasp of cucumber trait evolution and sets the stage for future breeding advancements.

Abstract
This study reports a graph-based cucumber pan-genome constructed from twelve chromosome-scale genome assemblies, revealing ~4.3 million genetic variants, including 56,214 structural variants (SVs). The pan-genome facilitated the identification of SVs associated with agronomic traits like fruit shape, flowering time, and root growth, enhancing our understanding of cucumber trait evolution and providing resources for breeding.
