Pollinator and herbivore effects on Erysimum
Erysimum capitatum (Brassicaceae) is a widespread and variable plant species with generalized pollination that is attacked by a number of herbivores. Lay et al. find that

Pollen–pistil interactions in the Asteraceae (Review)
Pollen–pistil interactions are an essential prelude to fertilization in angiosperms, and self-incompatibility (SI) is the best understood of these at a molecular level. Allen

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

Cabomba as a model basal angiosperm (Review)
Early-diverging angiosperms are important for studies of the origin and early evolution of the flower. Vialette-Guiraud et al. discuss the potential of the water

Why do petals have conical epidermal cells? (Review)
The conical epidermal cells found on the petals of most Angiosperm species are so widespread that they have been used as markers of petal identity, but

Stamen development and dormancy in apricot
Temperate woody perennials become dormant over winter; but dormancy is also a prerequisite for adequate flowering, thus limiting their cultivation at warmer latitudes. Julian et al.

Convoluted carbon cycle collection
Of all the biogeochemical cycles that help to sustain life on Earth, the carbon cycle is arguably the most important (although not necessarily the most straightforward!

Sexual selection, pollinators and floral dimorphism
Sexual selection mediated by animal pollinators can potentially drive dimorphism in plant populations with unisexual flowers. Yakimowski et al. compare variation in floral traits between populations

SI-mediated actin alterations in pollen (Review)
Self-incompatibility (SI) is generally controlled by the S-locus, and comprises allelic pollen and pistil S-determinants. Poulter et al. review and discuss our current

Pollen-tube growth in early angiosperms
The three earliest extant lineages of flowering plants are represented by only some 16 genera. Despite low species’ diversity, these genera are highly diverse in their
