We estimate the timing of the Arabidopsis thaliana whole-genome duplication by means of phylogenetic and statistical analysis, and propose two possible scenarios for the duplication. The first one, based on the assumption that the duplicated segments diverged from an autotetraploid form, places the duplication at about 38 million years ago, after the Arabidopsis lineage diverged from that of soybean (Glycine max) and before it diverged from its sister genus, Brassica. The second scenario assumes that the ancestor was allotetraploid, and suggests that the duplication is younger than 38 million years and may have contributed to the Arabidopsis-Brassica divergence. In each case, our estimate places the age of the genome duplication as significantly younger than previously reported.
