Polyploidy (whole‐genome duplication, WGD) is an integral feature of eukaryotic evolution
with two main forms typically recognized, autopolyploidy and allopolyploidy. In plants, a …

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 …

To conserve water in arid environments, numerous plant lineages have independently
evolved Crassulacean Acid Metabolism (CAM). Interestingly, Isoetes, an aquatic lycophyte …

Pollen grains are the male gametophytes in a seed‐plant life cycle. Their small, particulate
nature and crucial role in plant reproduction have made them an attractive object of study …

The large genomes of ferns have long deterred genome sequencing efforts. To date, only
two heterosporous ferns with remarkably small genomes, Azolla filiculoides and Salvinia …

Premise The gametophytes of different fern species collected in the field can be difficult to
distinguish because of their morphological similarities. Nonetheless, emerging molecular …

Key message Our results indicate the existence of interploidy gene flow in Cystopteris
fragilis, resulting in sexual triploid and diploid gametophytes from pentaploid parents …

Dragon's blood collected from the genus Dracaena is used as a renowned traditional
medicine in various cultures worldwide. However, the genetics of the genus Dracaena and …

The Chinese occurrences of the marattioid fern genus Christensenia have been considered
as requiring protection because of its extreme rarity and very small population size. Here, we …

Plants are sessile creatures that have to adapt constantly changing environmental
circumstances. Plants are subjected to a range of abiotic stressors as a result of …
