- A sorghum pangenome reference was constructed with 33 members to improve crop trait discovery.
- A diversity panel of 1,984 sorghum cultivars and landraces was analyzed to explore genetic diversity and adaptation.
- Multiple nested and deeply diverged structural variants were found in the domestication gene SHATTERING1, indicating a multicentric origin of sorghum.
- Landscape genomics revealed how gene flow and secondary contact created a complex genetic mosaic in breeding networks.
- Biosynthetic gene cluster structural variation was linked to phenotypic leaf concentration of the cyanogenic glucoside dhurrin.
- The study provides a framework for accelerating breeding and trait discovery in sorghum and other crops.
