Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …

Flow cytometry (FCM) using DNA-selective fluorochromes is now the prevailing method for
the measurement of nuclear DNA content in plants. Ease of sample preparation and high …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …

Polyploidy, the multiplication of chromosome sets above the diploid state, is arguably as
prevalent in plants as any other eukaryotic group. Over the past century, polyploidy has …

The ecological role of genome size in plant biology, biogeography, and morphology has
garnered increasing attention as the methods and technology associated with measuring …

Genome size has been suggested as one of the traits associated with invasiveness of plant
species. To provide a quantitative insight into the role of this trait, we estimated nuclear DNA …

Abstract Background and Aims Detailed knowledge of variations in ploidy levels and their
geographic distributions is one of the key tasks faced in polyploid research in natural …

Database of published chromosome numbers and ploidy-level estimates of the tribe
Alysseae is presented, together with the revised generic concept and the list of accepted …

Hybridization and polyploidization are important processes for plant evolution. However,
classification of hybrid or polyploid species has been notoriously difficult because of the …
