A taxonomic, genetic and ecological data resource for the vascular plants of Britain and Ireland.
The vascular flora of Britain and Ireland is among the most extensively studied in the world, but the current knowledge base is fragmentary, with taxonomic, ecological and genetic information scattered across different resources. Here we present the first comprehensive data repository of native and alien species optimized for fast and...Henniges, Marie C. ; Powell, Robyn F. ; Mian, Sahr ; Stace, Clive A. ; Walker, Kevin J. …

The Welwitschia genome reveals a unique biology underpinning extreme longevity in deserts.
The gymnosperm Welwitschia mirabilis belongs to the ancient, enigmatic gnetophyte lineage. It is a unique desert plant with extreme longevity and two ever-elongating leaves. We present a chromosome-level assembly of its genome (6.8 Gb/1 C) together with methylome and transcriptome data to explore its astonishing biology. We also present a refined, high-quality assembly...Wan, Tao ; Liu, Zhiming ; Leitch, Ilia J. ; Xin, Haiping ; Maggs-Kölling, Gillian …

Evolutionary dynamics of transposable elements and satellite DNAs in polyploid Spartina species
Repeated sequences and polyploidy play a central role in plant genome dynamics. Here, we analyze the evolutionary dynamics of repeats in tetraploid and hexaploid Spartina species that diverged during the last 10 million years within the Chloridoideae, one of the poorest investigated grass lineages. From high-throughput genome sequencing, we annotated...Giraud, Delphine ; Lima, Oscar ; Huteau, Virginie ; Coriton, Olivier ; Boutte, Julien …

Repeat-sequence turnover shifts fundamentally in species with large genomes.
Given the 2,400-fold range of genome sizes (0.06–148.9 Gbp (gigabase pair)) of seed plants (angiosperms and gymnosperms) with a broadly similar gene content (amounting to approximately 0.03 Gbp), the repeat-sequence content of the genome might be expected to increase with genome size, resulting in the largest genomes consisting almost entirely of repetitive...Novák, Petr ; Guignard, Maïté S. ; Neumann, Pavel ; Kelly, Laura J. ; Mlinarec, Jelena …
