Establishing the cell biology of apomixis in Boechera
The genus Boechera (Brassicaceae) is comprised of both sexual and apomictic species, permitting comparative analyses of meiotic disturbances and parthenogenesis. Hybridization, polyploidy and environmental adaptation...

Warming reduces stress in Antarctic moss
In moss-dominated regions of the Western Antarctic Peninsula, dramatic climate features have profoundly impacted moss biology and terrestrial ecology. In a study focused on the effects of six-years of passive warming on...

No sexual niche partitioning in a dioecious moss
Roughly half of the species of bryophytes have separate sexes (dioecious) and half are hermaphroditic (monoecious). This variation has major consequences for the ecology and evolution of the different species. In some...
Flooding and floral variation in a clonal aquatic plant
A report of variation in morph frequencies and floral traits in the tristylous clonal aquatic Eichhornia azurea in the Pantanal wetlands of Brazil.
Caught in the act…
A revelation concerning amber-encased plant material suggests current sexual reproduction in angiosperms may have changed little in over 100 million years.

Reproductive differentiation into sexual and apomictic cytotypes
Mechanisms enabling the maintenance of sexual and apomictic modes of seed formation in sympatry are poorly understood. Dobeš et al. study populations of Potentilla puberula representing various combinations of five...
Gene function, reproduction and climate change (Review)
Studies have suggested that plant sexual reproduction is particularly vulnerable to climate change, and a number of ecologically and evolutionarily relevant genes have recently been identified. Shimizu et al. consider...
TcCRP1 as a pollen-tube attractant in Torenia
A key factor of pollen-tube attraction to an ovule is that it is species-specific, and recently a family of secreted proteins with attractant properties has been discovered in Torenia fournieri. Kanaoka et al. study...
Apomixis is not prevalent in a high-alpine ecosystem
`Apomixis is not prevalent in a high-alpine ecosystem Apomixis (agamospermy) is expected to provide selective advantages in high alpine environments, where conditions tend to be unfavourable for sexual reproduction of...
