Genome Size Doubling Arises From the Differential Repetitive DNA Dynamics in the Genus Heloniopsis (Melanthiaceae).
Plant genomes are highly diverse in size and repetitive DNA composition. In the absence of polyploidy, the dynamics of repetitive elements, which make up the bulk of the genome in many species, are the main drivers underpinning changes in genome size and the overall evolution of the genomic landscape. The...Pellicer, Jaume ; Fernández, Pol ; Fay, Michael F. ; Michálková, Ester ; Leitch, Ilia J.

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 …

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 …
