Morphological and environmental differentiation as prezygotic reproductive barriers between parapatric and allopatric <i>Campanula rotundifolia</i> agg. cytotypes Open
Background and Aims Reproductive isolation and local establishment are necessary for plant speciation. Polyploidy, the possession of more than two complete chromosome sets, creates a strong postzygotic reproductive barrier between diploid …

Associations between genomic ancestry, genome size and capitula morphology in the invasive meadow knapweed hybrid complex (Centaurea × moncktonii) in eastern North America Open
Plant invasions are prime opportunities for studying hybridization and the nature of species boundaries, but hybrids also complicate the taxonomic treatment and management of introduced taxa. In this study, we use population genomics to es…

Ploidy‐altered phenotype interacts with local environment and may enhance polyploid establishment in<i>Knautia serpentinicola</i>(Caprifoliaceae) Open
Summary Whole genome duplication is a key process in plant evolution and has direct phenotypic consequences. However, it remains unclear whether ploidy‐related phenotypic changes can significantly alter the fitness of polyploids in nature …

Small genome separates native and invasive populations in an ecologically important cosmopolitan grass Open
The literature suggests that small genomes promote invasion in plants, but little is known about the interaction of genome size with other traits or about the role of genome size during different phases of the invasion process. By intercon…

Plastid capture and resultant fitness costs of hybridization in the Hirta clade of southern African Oxalis Open
Ancient hybridization leading to plastid capture is a likely cause of cytonuclear discordance, although discordance may also be attributed to other mechanisms. Cytonuclear discordance is ubiquitous in a clade of southern African Oxalis kno…

Evolutionary dynamics of mixed-ploidy populations in an annual herb: dispersal, local persistence and recurrent origins of polyploids Open
Diploids and tetraploids commonly coexist at all spatial scales and exhibit considerable temporal stability in local ploidy mixtures. Mixed-ploidy populations containing fertile triploid hybrids probaby act as effective generators of cytog…

Patterns, causes and consequences of genome size variation in Restionaceae of the Cape flora Open
Little is known about genome size (GS) variation in the hyperdiverse Cape flora of southern Africa. Towards filling this gap, we measured GS of 158 species of Cape Restionaceae and demonstrated >16-fold variation in 1C-values (0.47–7.66 pg…

Does higher ploidy level increase the risk of invasion? A case study with two geo-cytotypes of Solidago gigantea Aiton (Asteraceae) Open
Understanding the role of genetics in biological invasions has become an important aspect for modern plant ecology. Many studies suggest that increased ploidy level benefits the success of an invasive species, but the basis for this phenom…

Polyploid species rely on vegetative reproduction more than diploids: a re-examination of the old hypothesis Open
These findings confirm the old hypothesis that polyploids can rely on vegetative reproduction which thus may save many incipient polyploids from extinction. A closer analysis also shows that the sequence of events begins with development o…

Species‐rich and polyploid‐poor: Insights into the evolutionary role of whole‐genome duplication from the Cape flora biodiversity hotspot Open
PREMISE OF THE STUDY: Whole‐genome duplication (WGD) in angiosperms has been hypothesized to be advantageous in unstable environments and/or to increase diversification rates, leading to radiations. Under the first hypothesis, floras in st…

The Enigma of Progressively Partial Endoreplication: New Insights Provided by Flow Cytometry and Next-Generation Sequencing Open
In many plant species, somatic cell differentiation is accompanied by endoreduplication, a process during which cells undergo one or more rounds of DNA replication cycles in the absence of mitosis, resulting in nuclei with multiples of 2C …
