Biodiversity today has the unusual property that 85% of plant and animal species live on
land rather than in the sea, and half of these live in tropical rainforests. An explosive boost to …

Genome size is a biodiversity trait that shows staggering diversity across eukaryotes, varying
over 64,000-fold. Of all major taxonomic groups, land plants stand out due to their …

The large size and complexity of most fern genomes have hampered efforts to elucidate
fundamental aspects of fern biology and land plant evolution through genome-enabled …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of
land plants. Unfortunately, the timings of WGD events are loosely constrained and …

Premise of the Study Polyploidy or whole‐genome duplication (WGD) pervades the
evolutionary history of angiosperms. Despite extensive progress in our understanding of …

Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

Nitrogen (N) and/or phosphorus (P) availability can limit growth of primary producers across
most of the world's aquatic and terrestrial ecosystems. These constraints are commonly …

Chromosomal rearrangements (CRs) have been known since almost the beginning of
genetics. While an important role for CRs in speciation has been suggested, evidence …

Highlights•Post-polyploid diploidization (PPD) in angiosperms usually operates by
descending dysploidy.•PPD is acting with differing intensities and rates.•Multiple base …
