Plant genome size (GS) varies widely – by as much as a factor of 2500 in land plants alone. Outside of genome duplication (polyploidy), repetitive DNA is thought to be the main contributor to this variation. However...

Genepool of a year-long bean crop, Phaseolus dumosus
Studying the relationships between major crops and the secondary genepools of related species that are more resistant to climate challenges, Mina-Vargas et al. employ nuclear and chloroplast genetic markers to carry out...

Apomixis and reticulate evolution in Aspleniaceae
Ferns have the highest proportion of apomictic species in all plant groups, but the reasons for this are unclear. Dyer et al. determine the reproductive mode of species in the Asplenium monanthes fern complex, and use...
Reticulate evolution and triploidy in Diphasiastrum
Diphasiastrum species have been assumed to produce homoploid hybrids whose reproductive competence is still a matter of debate. Using flow cytometry, Bennert et al. demonstrate that the three Central European primary...
