Simplified 3D genome and gap-less CC group Oryza genome reveal genetic dynamics of rice triploid lines from distant hybridization

Intergeneric hybridization and domestication breeding is an efficient means for utilizing wild rice germplasm resources. In this study, we constructed gap-less genome assemblies for two CC, two BBCC and one CCDD wild rices to explore the role of the C subgenome in rice diversification. Furthermore, we assembled the genome of a cultivated rice (AA) and further developed A/C hybrids with enhanced resistance to BPH using an efficient hybrid embryo rescue system.
