| Abstract |
The Rf-1 locus in rice is agriculturally important as it restores fertility in plants with BT-type cytoplasmic male sterility (CMS). The Rf-1 locus contains several duplicated copies of the gene responsible for restoration of fertility. We analyzed the genomic structure of the Rf-1 locus in the genus Oryza to clarify the structural diversity and evolution of the locus. We identified six genes (Rf-1A to Rf-1F) with homology to Rf-1 at this locus in Oryza species with an AA genome. The Rf-1 locus structures in the rice accessions examined were very complex and fell into at least six classification types. The nucleotide sequences of the duplicated genes and their flanking regions were highly conserved suggesting that the complex Rf-1 locus structures were produced by homologous recombination between the duplicated genes. The fact that complex Rf-1 locus structures were common to Oryza species that have evolved independently indicates that a duplication of the ancestral Rf-1 gene occurred early in rice evolution and that homologous recombination resulted in the diversification of Rf-1 locus structures. Additionally, the amino acid sequences of each duplicated gene were conserved between species. This suggests that the duplicated genes in the Rf-1 locus may have divergent functions and may act by controlling mitochondrial gene expression in rice as occurs in the restoration of CMS.
