Oryza sativa Japonica Group vs Manihot esculenta LastZ results

Oryza sativa Japonica Group (Oryza sativa Japonica Group, IRGSP-1.0) and Manihot esculenta (Manihot esculenta, Manihot_esculenta_v6) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl Plants release 91. Oryza sativa Japonica Group was used as the reference species. After running LastZ, the raw LastZ alignment blocks were chained according to their location in both genomes. During the final netting process, the best sub-chain was chosen in each region on the reference species.
