Knowledge of evolution of genome size in species with holocentric chromosomes is limited. Lipnerová et al. study genome size and base composition in the holocentric genus Carex (Cyperaceae) in relation to chromosome number. They find that genomes are relatively small and very GC-poor compared with other angiosperms, with genome size positively correlated with GC content and [...]

Genome size is known to affect various plant traits such as stomatal size and seed mass but these associations are not well understood for species with very large genomes, which are largely represented by geophytic plants. Veselý et al.  survey genome size across 219 geophytes and find that it is associated with species’ ecology and phenology, [...]
