Aim Speciation can either proceed as gradual divergence, mostly in allopatry or parapatry,
or by duplication of chromosome sets: polyploidization. Hybrid‐origin or allopolyploidization …

The genus Phaseolus L. has been subject of extensive cytogenetic studies due to its global
economic importance. It is considered karyotypically stable, with most of its ca. 75 species …

Background and aims Brassica napus (AACC, 2 n= 38, oilseed rape) is a relatively recent
allotetraploid species derived from the putative progenitor diploid species Brassica rapa …

Background Although karyologically well studied, the genus Tanacetum (Asteraceae) is
poorly known from the perspective of molecular cytogenetics. The prevalence of polyploidy …

Among cereals, triticale (× Trititcoseale Wittmack ex A. Camus) represents a number of
advantages such as high grain yield even in marginal environments, tolerance to drought …

Paramutation is a form of non-Mendelian inheritance in which the expression of a
paramutable allele changes when it encounters a paramutagenic allele. This change in …

Polyploidization is a significant evolutionary force in plants which involves major genomic
and genetic changes, frequently regulated by epigenetic factors. We explored whether …

Polyploidization plays an important role in plant adaption to adverse environments, but the
mechanism by which polyploidization confers adaptation to cold stress remains elusive …

PREMISE OF THE STUDY: Shifts in ploidy affect the evolutionary dynamics of genomes in a
myriad of ways. Population genetic theory predicts that transposable element (TE) …

Polyploidization, the increase in genome copies, is considered a major driving force for
speciation. We have recently provided the first direct in planta evidence for polyspermy …
