Abstract: Double dealing in the plant genome Gene and genome duplications are major factors in plant evolution. A high-resolution phylogenomic analysis of genes from sequenced genomes and more than 12.6 million expressed-sequence tags from pivotal gymnosperm and basal angiosperm species has identified two ancient whole-genome duplications. One occurred in the common ancestor of extant seed plants and the other in the common ancestor of the angiosperms.
