Phylogenetic relationships among A‐genome species of the genus Oryza revealed by intron sequences of four nuclear genes
Open accessAbstract
Summary: • The A‐genome group in Oryza consists of eight diploid species and is distributed world‐wide. Here we reconstructed the phylogeny among the A‐genome species based on sequences of nuclear genes and MITE (miniature inverted‐repeat transposable elements) insertions. • Thirty‐seven accessions representing two cultivated and six wild species from the A‐genome group were sampled. Introns of four nuclear single‐copy genes on different chromosomes were sequenced and analysed by both maximum parsimony (MP) and Bayesian inference methods. • All the species except for Oryza rufipogon and Oryza nivara formed a monophyletic group and the Australian endemic Oryza meridionalis was the earliest divergent lineage. Two subspecies of Oryza sativa (ssp. indica and ssp. japonica) formed two separate monophyletic groups, suggestive of their polyphyletic origin. Based on molecular clock approach, we estimated that the divergence of the A‐genome group occurred c. 2.0 million years ago (mya) while the two subspecies (indica and japonica) separated c. 0.4 mya. • Intron sequences of nuclear genes provide sufficient resolution and are informative for phylogenetic inference at lower taxonomic levels.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
