Allopolyploidy has been a prominent speciation mechanism and a recurrent process during plant evolution that has contributed greatly to the large number of duplicated genes in plant genomes.Polyploidy often leads to changes in genome organization and gene expression.The expression of genes duplicated by polyploidy,termed homeologs,can be partitioned between the duplicates so that one copy is expressed and functions only in some organs and the other copy is expressed only in other organs,indicative of subfunctionalization.
