Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Biological invasions impose ecological and economic problems on a global scale, but also
provide extraordinary opportunities for studying contemporary evolution. It is critical to …

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 …

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, the possession of more than 2 complete genomes, is a major force in plant
evolution known to affect the genetic and genomic constitution and the phenotype of an …

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

Spartina species of the mid-low intertidal areas are powerful ecological engineers that are
highly valued where they are native. Elsewhere, they overgrow native salt marsh and open …

Nearly four decades ago, Roose & Gottlieb (Roose & Gottlieb 1976 Evolution 30, 818–
830.(doi: 10.2307/2407821)) showed that the recently derived allotetraploids Tragopogon …

In 2014, a DNA‐based phylogenetic study confirming the paraphyly of the grass subtribe
Sporobolinae proposed the creation of a large monophyletic genus Sporobolus, including …
