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 …

Heterosis, also known as hybrid vigour, is widespread in plants and animals, but the
molecular bases for this phenomenon remain elusive. Recent studies in hybrids and …

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

Background The growing wealth of knowledge on whole-plant genome sequences is
highlighting the key role of transposable elements (TEs) in plant evolution, as a driver of …

Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

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 …

Genome doubling (polyploidy) has been and continues to be a pervasive force in plant
evolution. Modern plant genomes harbor evidence of multiple rounds of past …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Polyploidy, or whole-genome duplication (WGD), is an important genomic feature for all
eukaryotes, especially many plants and some animals. The common occurrence of …

Segregating hybrids and stable allopolyploids display morphological vigour,,, and
Arabidopsis allotetraploids are larger than the parents Arabidopsis thaliana and Arabidopsis …
