Crop acquisition of phosphorus, iron and zinc in intercropping (Review)
Phosphorus (P), iron (Fe) and zinc (Zn) are essential elements for plant growth and development but their availability in soil is often limited. Xue et al.

Leaf mechanical traits in insect herbivory
Leaf mechanical traits deter insect herbivores, but little is known about the role of particular mechanical traits across feeding guilds. Caldwell et al. investigated feeding damage

Examining the impact of heterospecific pollen deposition in the field
Most work on the impacts of heterospecific pollen deposition on plant fecundity has utilized hand-pollination experiments in greenhouse settings, and therefore we know little about

Style morph frequencies in tristylous Lythrum
A balance between stochastic processes and negative frequency-dependent selection largely determines style morph frequencies in heterostylous populations. Costa et al. investigate variation in morph frequencies

Density-dependent reproduction regulated by kinship and tree size
Global pollinator declines and habitat fragmentation highlight the critical need to understand reproduction and gene flow across plant populations. Castilla et al. use spatial, reproductive, and

Correlated polymorphism in cytotype and sexual system
Polyploidy has important effects on plant reproductive systems and previously has been implicated in the evolution of dimorphic reproductive strategies. Miller et al. use flow cytometry,

Floral integration is more related to mating than pollination system
Almost 60 years ago, Berg proposed that floral integration and pollination system should be associated as a consequence of the selective pressures promoting successful cross-pollination.

Effect of nectar robbing on a pollinator-dependent plant
Nectar robbing commonly has negative consequences for the reproductive success of plants. Because total plant fitness is the result of both female and male functions, Rojas-

Space matters in flower development
Flower meristems have the capacity to expand throughout their development, generating space for new structures. Claßen-Bockhoff and Meyer demonstrated this by the example of corona

Ecological differentiation of Senecio by ploidy is stronger in areas of sympatry
Characterizing ecological niches via Landolt indicator values of accompanying species, Sonnleitner et al. found that niches of four groups (two diploids, one tetraploid, one hexaploid) of Senecio carniolicus s.l. (Asteraceae) differed with respect to temperature, light and soil properties, but not i

Pyrophosphatase and sucrose synthase suggest apoplasmic loading in rice
Whether rice uses an energy-dependent apoplasmic or a passive symplasmic strategy of phloem loading is still not resolved.

Seed dormancy cycling and mortality in Arabidopsis thaliana
The contribution of variation in seed bank dynamics to local adaptation is not well studied. Postma et al. investigated the extent to which genetic and environmental
