By resequencing 630 gene fragments of rice chromosomes from wild and cultivated accessions, researchers led by New York University's Michael Purugganan were able to infer the evolutionary history of rice, as they report in this week's PNAS. The team took both a diffusion-based approach to model the SNP data and a Bayesian evolutionary approach for its phylogenetic analyses. These studies, the team says, suggest a single origin of rice that dates to about 8,200 to 13,500 years ago.
