Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

The application of new molecular technology has greatly increased our understanding of the
role of chromosomal change in plant evolution. There is now a broad database on genome …

Meiosis includes two successive divisions of the nucleus with one round of DNA replication
and leads to the formation of gametes with half of the chromosomes of the mother cell during …

The idea of evolution as a principle for the origin of biodiversity fits all phenomena of life,
including the carriers of nuclear inheritance, the chromosomes. Insights into the evolutionary …

Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

All crop plants are polyploid and some genomes have been duplicated more recently than
others. Advancements in cytogenetic and molecular tools, including high‐density genetic …

The plant genome is organized into chromosomes that provide the structure for the genetic
linkage groups and allow faithful replication, transcription and transmission of the hereditary …

Gene duplication, arising from region-specific duplication or genome-wide polyploidization,
is a prominent feature in plant genome evolution. Understanding the mechanisms …

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 …

Perhaps all flowering plants have experienced one or more episodes of polyploidization at
some time in their evolutionary history. Recent evidence indicates that this genome doubling …
