Note: in the investigated 808 accessions, 417 accessions (in parentheses) carry predominant forms (in high copy numbers) of the structures that were detected by PCR with 28 cycles. The recombinant structures with very low copy numbers that co-exist with the predominant structures in some accessions (see Figure 5) are not included here. The nine Oryza species (no. accessions analyzed) from which no these structures were detected are: O. australiensis (2), O. barthii (4), O. brachyantha (3), O. glumaepatula (2), O. grandiglumis (2), O. latifolia (3), O. longistaminata (4), O. meridionalis (2), and O. punctata (3).
