An angiosperm-wide perspective on reproductive strategiesand floral traits

The paper analyzes floral and reproductive traits across 361 flowering plant species to show that dioecy is linked to floral traits, while correlations with lifespan and dispersal are spurious.

Pre-zygotic mate selection affects progeny fitness and is only partially correlated with the expression of NaS-like RNases

The paper investigates how pre-zygotic mate selection in Nicotiana attenuata affects progeny fitness and links it to ethylene signaling and SLR gene expression.

Rapid divergence in vegetative morphology of a wind-pollinated plant between populations at contrasting densities

The paper shows that changing plant density rapidly induces age-dependent and sex-specific evolution in vegetative traits of Mercurialis annua through experimental evolution.

Herbivory enhances leaky sex expression in the dioecious herb Mercurialis annua

This study shows that simulated herbivory increases leaky sex expression in both male and female Mercurialis annua plants, with greater leakiness observed in larger females.

High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron, the most sexually dimorphic angiosperms

The paper investigates the evolution of sex-biased gene expression in Leucadendron, finding that high expression evolution rates preceded the development of sex bias.

The evolution of sex allocation in metapopulations

This study investigates how population turnover in metapopulations affects sex allocation in hermaphroditic species, finding that it can favor female-biased sex ratios, especially with low dispersal.

Rapid dissolution of dioecy by experimental evolution

This study shows that dioecy can rapidly revert to hermaphroditism in plants through experimental evolution by increasing female male-flower production.

A ghost of dioecy past and the legacy of sexual dimorphism: low siring success of hermaphrodites after the breakdown of dioecy

The paper compares siring success of female-derived hermaphrodites with male-like hermaphrodites in Mercurialis annua, finding lower siring success in female-derived hermaphrodites, supporting the idea that remnants of dioecy reduce fitness in outcrossing populations.
