Mixed-ploidy species harbor a unique form of genomic and phenotypic variation that
influences ecological interactions, facilitates genetic divergence, and offers insights into the …

An unintended consequence of global change is an increase in opportunities for
hybridization among previously isolated lineages. Here we illustrate how global change can …

Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and
asexual reproduction, often simultaneously. The commonest type of asexual reproduction is …

Background Species diversity is likely to undergo a sharp decline in the next century.
Perhaps as many as 33% of all plant species may expire as a result of climate change. All …

Allopolyploidization (hybridization and whole-genome duplication) is a common
phenomenon in plant evolution with immediate saltational effects on genome structure and …

Speciation rates need to be considered when estimating human impacts on the numbers of
species on Earth, given that past mass extinctions have been followed by the accelerated …

This article describes the use of cytogenomic and molecular approaches to explore the
origin and evolution of Cardamine schulzii, a textbook example of a recent allopolyploid, in …

The genus Mimulus is a well-studied group of plant species, which has for decades allowed
researchers to address a wide array of fundamental questions in biology (Wu & al., 2008; …

Whole genome duplication (polyploidization) is a mechanism of “instantaneous” species
formation that has played a major role in the evolutionary history of plants. Much of what we …
