Flow cytometry (FCM) is currently the most widely‐used method to establish nuclear DNA
content in plants. Since simple, 1‐3‐parameter, flow cytometers, which are sufficient for most …

A critical aspect for obtaining accurate, reliable, and high‐resolution estimates of nuclear
DNA content is the release of nuclei from the cytoplasm in sufficient amounts, while …

Over the years, the amount of DNA in a nucleus (genome size) has been estimated using a
variety of methods, but increasingly, flow cytometry (FCM) has become the method of choice …

Apomictic plants expand their geographical distributions more to higher elevations
compared to their sexual progenitors. It was so far unclear whether this tendency is related …

Polyploidy is one of the most important evolutionary processes in plants. In natural
populations, polyploids usually emerge from unreduced gametes which either fuse with …

Hybridisation and polyploidy are major forces contributing to plant speciation. Homoploid
(2x) and heteroploid (3x) hybrids, however, represent critical stages for evolution due to …

Background The predominance of sex in eukaryotes, despite the high costs of meiosis and
mating, remains an evolutionary enigma. Many theories have been proposed, none of them …

Meiosis, the key step of sexual reproduction, persists in facultative apomictic plants
functional to some extent. However, it still remains unclear how and why proportions of …

Key message The combination of a flow cytometric seed screen and genotyping of each
single seed offers a cost-effective approach to detecting complex reproductive pathways in …

• Premise of the study: Amelanchier polyploid apomicts differ from sexual diploids in their
more complex diversification, greater species problems, and geographic distribution. To …
