Alpine oceanic ecosystems are considered amongst the most ephemeral and restricted habitats, with a biota highly vulnerable to climate changes and disturbances. As an example of an alpine insular endemic, Rodríguez...

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.

Ongoing gene flow among Australian alpine Poa
Recently radiated groups pose a taxonomic challenge even with extensive molecular data, as they may be genetically differentiated only at small and/or patchy regions of the genome. Griffin and Hoffmann investigate...

Genome downsizing and karyotype constancy in diploid and polyploid congeners: a model of genome size-variation
In several genera evolutionary chromosome change involves variation in DNA amount in diploids and genome downsizing in polyploids. In a new study in AoB PLANTS, Poggio et al. analysed the genome size and karyotypical...

Assignment of SNP allelic configuration in polyploids
Estimation of allele copy numbers for molecular markers is a challenge for polyploid species.
