Ancestral Karyotype Reconstruction Reveals Chromosome Rearrangements and Large Inversions in Oryza
A stable chromosome count does not imply a static genome. Oryza species have largely retained a basic chromosome number of 12, yet most rearrangements are described against extant references, making ancestral and derived orientations difficult to distinguish. We reconstructed an ancestral Oryza karyotype (AOK) containi...
