Telomere-to-telomere African wild rice (Oryza longistaminata) reference genome reveals segmental and structural variation.

ABSTRACT: Rice (Oryza sativa) is one of the most important staple food crops worldwide, and its wild relatives serve as an important gene pool in its breeding. Compared with cultivated rice species, African wild rice (Oryza longistaminata) has several advantageous traits, such as resistance to increased biomass production, clonal propagation via rhizomes, and biotic stresses. However, previous O. longistaminata genome assemblies have been hampered by gaps and incompleteness, restricting detailed investigations into their genomes. To streamline breeding endeavors and facilitate functional genomics studies, we generated a 331-Mb telomere-to-telomere (T2T) genome assembly for this species using a hybrid approach combining PacBio HiFi, Hi-C, and CycloneSEQ ultra-long reads, covering all telomeres and ce
