Genome size (GS) variation is a fundamental biological characteristic; however, its
evolutionary causes and consequences are the topic of ongoing debate. Whether GS is a …

The morphological and ecological intermediacy of hybrid taxa has long interested and
challenged fern biologists, resulting in numerous systematic contributions focused on …

The abrupt origin and rapid diversification of the flowering plants during the Cretaceous has
long been considered an “abominable mystery.” While the cause of their high diversity has …

The genome evolution of ferns has been considered to be relatively static compared with
angiosperms. In this study, we analyse genome size data and chromosome numbers in a …

Background Comprehensive biotic surveys, or 'all taxon biodiversity inventories'(ATBI), have
traditionally been limited in scale or scope due to the complications surrounding specimen …

Genome size is an indicator of evolutionary distance and a metric for genome
characterization. Here, we report accurate estimates of genome size in 99 accessions from …

Simple Summary The amount of hereditary information (DNA) contained in the cell nuclei of
larger or more complex organisms is often no greater than that of smaller or simpler …

Polyploidy, or genome doubling, has occurred repeatedly through plant evolution. While
polyploid plants are used extensively in agriculture and horticulture, they have so far found …

Ferns and lycophytes have remarkably large genomes. However, little is known about how
their genome size evolved in fern lineages. To explore the origins and evolution of …

The significance of the wide interspecific variation in nuclear genome size of angiosperms is
still not fully understood. It has been repeatedly suggested, however, that genome size can …
