Abstract Rice (Oryza sativa L.) is a vital staple food globally, but its genetic diversity has decreased due to extensive breeding. However, research on genome evolution and of wild rice species, particularly those with BB, CC, BBCC, CCDD, EE, FF, GG types, limited, impeding their potential in breeding1,2. This study presents chromosome-scale genomes thirteen representatives species from the Oryza genus. By integrating these four previously published ones, total 101,723 gene families were identified across genus, including 9,834 (9.67%) core families. Additionally, 63,881 new absent cultivated discovered. Comparative genomic analysis among reveals mechanisms underlying size variation, centromere evolution, number expression influenced by transposable elements. Extensive structural rearrangements, large scale sub-genomes exchanges, widespread allelic variations regulatory sequence discovered rice. We noticed an inversion that are pervasive occurred Oryza rufipogon japonica, which tightly linked locus might contributed expansion geographical range. Interestingly, notable less disease resistance genes was observed, likely random loss some R amplification others for specific diseases during domestication artificial selection. comprehensive not only provide hidden legacy accessible studies breeding also deepens our understanding biology.
