Previous studies based on morphological and molecular markers indicated that there are two cultivated and five wild rice species within the Oryza genus with the AA genome. In the cultivated rice species, Oryza sativa, a retroposon named p-SINE1 has been identified. Some of the p-SINE1 members characterized previously showed interspecific insertion polymorphisms in the species with the AA genome. In this study, we identified new p-SINE1 members showing interspecific insertion polymorphisms from representative strains of four wild rice species with the AA genome: O. barthii, O. glumaepatula, O. longistaminata, and O. meridionalis. Some of these members were present only in strains of one species, whereas the others were present in strains of two or more species. The p-SINE1 insertion patterns in the strains of the Asian and African cultivated rice species O. sativa and O. glaberrima were very similar to those of the Asian and African wild rice species O. rufipogon and O. barthii, respectively. This is consistent with the previous hypothesis that O. sativa and O. glaberrima are derived from specific wild rice species. Phylogenetic analysis based on the p-SINE1 insertion patterns showed that the strains of each of the five wild rice species formed a cluster. The strains of O. longistaminata appear to be distantly related to those of O. meridionalis. The strains of these two species appear to be distantly related to those of three other species, O. rufipogon, O. barthii and O. glumaepatula. The latter three species are closely related to one another with O. barthii and O. glumaepatula being most closely related. A phylogenetic tree including a hypothetical ancestor with all loci empty for p-SINE1 insertion showed that the strains of O. longistaminata are related most closely to the hypothetical ancestor. This indicates that O. longistaminata and O. meridionalis diverged early on, whereas the other species diverged relatively recently, and suggests that the Oryza genus with AA genome might have originated in Africa, rather than in Asia.
