The causes and molecular consequences of polyploidy in flowering plants.

Author information

Programs in Genetics; Quantitative Biology.


Polyploidy is an important force shaping plant genomes. All flowering plants are descendants of an ancestral polyploid species, and up to 70% of extant vascular plant species are believed to be recent polyploids. Over the past century, a significant body of knowledge has accumulated regarding the prevalence and ecology of polyploid plants. In this review, we summarize our current understanding of the causes and molecular consequences of polyploidization in angiosperms. We also provide a discussion on the relationships between polyploidy and adaptation and suggest areas where further research may provide a better understanding of polyploidy.
