We have witnessed an explosion in our understanding of the evolution and structure of plant
genomes in recent years. Here, we highlight three important emergent realizations:(1) that …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

An essay on how modern flowering plant genomes are derived from processes of repeated,
episodic whole-genome doubling, or polyploidy, is presented. Topics discussed include …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

Allopolyploidy involves hybridization and duplication of divergent parental genomes and
provides new avenues for gene expression. The expression levels of duplicated genes in …

The last decade highlighted polyploidy as a rampant evolutionary process that triggers
drastic genome reorganization, but much remains to be understood about their causes and …

Polyploidy, the condition of possessing more than 2 complete chromosome sets in the same
nucleus, is frequent in nature and has implications for a species' prospects for evolution …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …
