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

Gymnosperms are a unique lineage of plants that currently lack a high-quality reference
genome due to their large genome size and high repetitive sequence content. Here, we …

Gymnosperms represent an ancient lineage that diverged from early spermatophytes during
the Devonian. The long fossil records and low diversity in living species prove their complex …

Inferring the intrinsic and extrinsic drivers of species diversification and phenotypic disparity
across the tree of life is a major challenge in evolutionary biology. In green plants, polyploidy …

Gnetophytes are an enigmatic gymnosperm lineage comprising three genera, Gnetum,
Welwitschia and Ephedra, which are morphologically distinct from all other seed plants …

Cycads represent one of the most ancient lineages of living seed plants. Identifying genomic
features uniquely shared by cycads and other extant seed plants, but not non-seed …

The polycomb repressive complex 2 (PRC2) regulates epigenetic gene repression in
eukaryotes. Mechanisms controlling its developmental specificity and signal-responsiveness …

Whole genome duplication (WGD) events are common in many plant lineages, but the
ploidy status and possible occurrence of intraspecific ploidy variation are unknown for most …

Gene tree–species tree reconciliation methods have been employed for studying ancient
whole-genome duplication (WGD) events across the eukaryotic tree of life. Most approaches …

Background Polyploidy, or whole-genome duplications (WGDs), repeatedly occurred during
green plant evolution. To examine the evolutionary history of green plants in a …
