Oryza rufipogon, the progenitor of the cultivated rice species Oryza sativa, is known by its wide intraspecific variation. In this study, we performed phylogenetic analyses of O. rufipogon strains and their relationships to O. sativa strains by using 26 newly identified p-SINE1 members from O. rufipogon strains, in addition to 23 members previously identified from O. sativa strains. A total of 103 strains of O. rufipogon and O. sativa were examined for the presence and absence of each of the p-SINE1 members at respective loci by PCR with a pair of primers that hybridize to the regions flanking each p-SINE1 member. A phylogenetic tree constructed on the basis of the insertion polymorphism of p-SINE1 members showed that O. rufipogon and O. sativa strains are classified into three groups. The first group consisted of O. rufipogon perennial strains mostly from China and O. sativa ssp. japonica strains, which included javanica strains forming a distinct subgroup. The second group consisted of almost all the O. rufipogon annual strains, a few O. rufipogon perennial strains and O. sativa ssp. indica strains. These groupings, in addition to other results, support the previous notion that annual O. rufipogon originated in the O. rufipogon perennial population, and that O. sativa originated polyphyletically in the O. rufipogon populations. The third group consisted of the other perennial strains and intermediate-type strains of O. rufipogon, in which the intermediate-type strains are most closely related to a hypothetical ancestor with no p-SINE1 members at the respective loci and to those belonging to the other rice species with the AA genome. This suggests that O. rufipogon perennial strains are likely to have originated from the O. rufipogon intermediate-ecotype population.
