Polyploidy is characterized by the presence of two or more complete sets of chromosomes coming from intraspecies whole-genome duplication (i.e., autopolyploidy) or from hybridization between distinct but related species (i.e., allopolyploidy).Poly-ploidization is a driving force in the evolution of higher plants,most of the plant species have experienced ancient or recent genome duplication events that have led to several genome modifications, such as chromosomal reorganization, gene conversion, sub-genome dominance, alteration of gene expression patterns, and expansion/contraction of some gene families.
