| 摘要 | Rapid radiations have long been regarded as the most challenging issue for elucidating poorly resolved phylogenies in evolutionary biology. The eight diploid AA- genome species in the genus Oryza represent a typical example of a closely spaced series of recent speciation events in plants. However, questions regarding when and how they diversified have long been an issue of extensive interest but remain a mystery. Here, a data set comprising >60 kb of 53 singleton fragments and 16 intergenic regions is used to perform phylogenomic analyses of all eight AA- genome species plus four diploid Oryza species with BB-, CC-, EE- and GG- genomes. We fully reconstruct phylogenetic relationships of AA- genome species with confidence. Oryza meridionalis, native to Australia, is found to be the earliest divergent lineage around 2.93 mya, whereas O. punctata, a BB- genome species, serves as the best outgroup to distinguish their phylogenetic relationships. They separated from O. punctata approximately 9.11 mya during the Miocene epoch, and subsequently radiated to generate the entire AA- genome lineage diversity. The success in resolving the phylogeny of AA- genome species highlights the potential of phylogenomics to determine their divergence and evolutionary histories. (C) 2013 Elsevier Inc.
