Plants are remarkable with regard to their capability to go beyond diploidy and remain in seemingly stable polyploid states.It is estimated that more than 50% of flowering plants are polyploids.Theory predicts that most gene duplicates tend to degenerate and disappear,so the high level of paralog retention in plants is puzzling.The extent of paralog survival is so important that protein diversity in plants is thought to be generated primarily through gene duplication rather than by alternative splicing.The fate of gene duplicates has been explored once and again.
