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 downsizing after polyploidy: mechanisms, rates and selection pressures.
An analysis of over 10,000 plant genome sizes (GS) indicate that most species have smaller genomes than expected given the incidence of polyploidy in their ancestries, suggesting selection for genome downsizing. However, ...
Exploring environmental selection on genome size in angiosperms.
Angiosperms show a remarkable range in genome size (GS), yet most species have small genomes, despite the frequency of polyploidy and repeat amplification in the ancestries of most lineages. It has been suggested that ...
