Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Highlights•Polyploidy or whole-genome duplication (WGD) is a ubiquitous feature of plant
genomes.•Polyploidy is most frequent in angiosperms.•A complex pattern of polyploidy is …

Green plants (Viridiplantae) include around 450,000–500,000 species, of great diversity and
have important roles in terrestrial and aquatic ecosystems. Here, as part of the One …

Long terminal repeat retrotransposons (LTR-RTs) are prevalent in plant genomes. The
identification of LTR-RTs is critical for achieving high-quality gene annotation. Based on the …

Water lilies belong to the angiosperm order Nymphaeales. Amborellales, Nymphaeales and
Austrobaileyales together form the so-called ANA-grade of angiosperms, which are extant …

Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

Allium crop breeding remains severely hindered due to the lack of high-quality reference
genomes. Here we report high-quality chromosome-level genome assemblies for three key …

Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …

Tea is the world's oldest and most popular caffeine-containing beverage with immense
economic, medicinal, and cultural importance. Here, we present the first high-quality …

The Allium genus is cultivated globally as vegetables, condiments, or medicinal plants and
is characterized by large genomes and strong pungency. However, the genome evolution …
