Characterization of the satellitome in lower vascular plants: the case of the endangered fern Vandenboschia speciosa
Vandenboschia speciosa is a highly vulnerable fern species, with a large genome (10.5 Gb). Haploid gametophytes and diploid sporophytes are perennial, can reproduce vegetatively, and certain populations are composed...

Comparative analysis of repetitive sequences among species from the potato and the tomato clades
The genus Solanum includes important vegetable crops and their wild relatives. Introgression of their useful traits into elite cultivars requires effective recombination between hom(e)ologues, which is partially...
Retrotransposons in holocentric chromosomes of Eleocharis with different ploidy levels
Long terminal repeat-retrotransposons (LTR-RTs) comprise a large portion of plant genomes, with massive repeat blocks distributed across the chromosomes. Eleocharis (Cyperaceae) species have holocentric chromosomes, and...
Hybrids face a battle for dominance of the genome
When two different genomes come together in a hybrid or polyploid, it can trigger conflict in the new genome. A review in New Phytologist investigates how one subgenome can become dominant.

Epigenetic floral variant of clonal oil palm (Review)
The mantled somaclonal variation of oil palm (Elaeis guineensis) hampers oil production as the supernumerary female organs are either sterile or produce fruits with poor oil yields. Jaligot et al. provide an overview of...
Repetitive components of Fritillaria genomes
Repetitive components of Fritillaria genomes The genus Fritillaria (Liliaceae) comprises species with some of the largest genomes so far reported. Ambrožová et al. examine the contribution of major repetitive elements...
