Rice (Oryza sativa L.) was probably domesticated from O. rufipogon in Asia in the last 10,000 years. Relatives of cultivated rice (A genome species of Oryza) are found in South America, Africa, Australia and Asia. These A genome species are the close relatives of cultivated rice and represent the effective gene pool for rice improvement. Members of this group in Northern Australia include, an annual species, O. meridionalis, and two recently distinguished perennial taxa, to one of which the name O. rufipogon has been applied and the other a perennial form of O. meridionalis. Comparison of whole chloroplast genome sequences of these taxa has now been used to determine the relationships between the wild taxa and cultivated rice. The chloroplast genomes of the perennials were both found to be distinguished from O. rufipogon from Asia by 124 or 125 variations and were distinguished from each other by 53 variations. These populations have remained isolated from the overwhelming genetic impact of the large domesticated rice populations in Asia and may be unique descendants of the gene pool from which domesticated rice arose. The conservation of this wild genetic resource may be critical for global food security.
