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.

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

Pathway of maize pollen tubes
Processes regulating pollen germination, growth, guidance and sperm delivery are considered major hybridization controls in nature and contribute to reproductive success as well as to isolation

Proteins, pollen tube growth and guidance
Pollination is a vital step for successful fertilization and seed formation in the angiosperms. Chae and Lord outline the crucial roles of small, secreted proteins in
