Polyploidization has played a major role in crop plant evolution, leading to advantageous
traits that have been selected by humans. Here, we describe restructuring patterns in the …

Publisher Summary This chapter provides an overview of the current state of knowledge
concerning genome size evolution in plants. It includes a review of available data, the …

Evolutionary biologists are increasingly comparing gene expression patterns across
species. Due to the way in which expression assays are normalized, such studies provide …

Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of
land plants. Unfortunately, the timings of WGD events are loosely constrained and …

Allopolyploid plants are hybrids that contain two copies of the genome from each parent.
Whereas wild and cultivated allopolyploids are well adapted, man-made allopolyploids are …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

Pan-genomics can encompass most of the genetic diversity of a species or population and
has proved to be a powerful tool for studying genomic evolution and the origin and …

Gene duplication and loss contribute to gene content differences as well as phenotypic
divergence across species. However, the extent to which gene content varies among closely …

Background Recent genome-wide studies suggested that in addition to genetic variations,
epigenetic variations may also be associated with differential gene expression and growth …
