Avoidance of interspecific pollen transfer in Pedicularis
Plants surrounded by individuals of other co-flowering species may attract more pollinators but can suffer a reproductive cost from interspecific pollen transfer. Yang et al.

Hydrochoric gene flow in invasive riparian Impatiens
Riparian systems are prone to invasion by alien plant species, which may be facilitated by hydrochory, the transport of seeds by water.

Evolutionary history of Afro-Madagascan Ixora
The pantropical genus Ixora is one of the largest genera in Rubiaceae, with approximately 530 species. Tosh et al. conduct phylogenetic analyses based on four plastid

Biomechanics of aquatic plants under aerial conditions
Aquatic plants can be exposed to aerial conditions during periods of low water level, but their biomechanical responses to this have had little attention.

Abscisic acid underlies genotypic variation in stomatal responses
Stomata formed at high relative humidity (RH) are less responsive to abscisic acid (ABA), an effect that varies widely between genotypes. Giday et al. study four

Corolla morphology and diversification rates in toadflaxes
Results suggest that opposing individual-level/species-level selection pressures have driven evolution of pollinator-restrictive traits in bifid toadflaxes.

Stabilization of yield in plant genotype mixtures
Arabidopsis thaliana genotype mixtures under strong competition and abiotic stress achieve more stable seed production through compensatory interactions.

Control of quiescent centre formation in adventitious roots
Accumulation of auxin and the expression of the QC marker WOX5 characterize the early derivatives of the AR founder cells both in planta and in explants.

Pollen receipt and quality in endemic-rich communities
The magnitude of pollen limitation is highly variable among habitats, species and differing plant communities. Alonso et al. analyse natural variability in pollen receipt and tube

Cluster roots, P and growth rate in Lupinus
Some Lupinus species produce cluster roots in response to low plant phosphorus (P) status. Wang et al. measure relative growth rate (RGR) among three lupin species,
