Main conclusion This article provides an up-to-date review concerning from basic issues of
polyploidy to aspects regarding the relevance and role of both natural and artificial …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

The allotetraploid plant Nicotiana tabacum (common tobacco) is a major crop species and a
model organism, for which only very fragmented genomic sequences are currently available …

Abstract Background Tobacco (Nicotiana tabacum) is an important plant model system that
has played a key role in the early development of molecular plant biology. The tobacco …

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

Heterosis refers to the phenomenon that progeny of diverse varieties of a species or crosses
between species exhibit greater biomass, speed of development, and fertility than both …

It has been argued that the evolution of plant genome size is principally unidirectional and
increasing owing to the varied action of whole-genome duplications (WGDs) and mobile …

Abstract Background and Aims The amount of DNA in an unreplicated gametic chromosome
complement is known as the C-value and is a key biodiversity character of fundamental …

The duplication of an entire genome is no small affair. Whole genome duplication (WGD) is
a dramatic mutation with long-lasting effects, yet it occurs repeatedly in all eukaryotic …

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 …
