Sexual selection: an evolutionary force in plants?
It is concluded that sexual selection can be a useful tool when studying the evolution of reproductive traits in plants and by including the evidence from an additional kingdom, a fuller understanding of the processes involved in sexual selectioncan be gained.
Earlier occurrence and increased explanatory power of climate for the first incidence of potato late blight caused by Phytophthora infestans in Fennoscandia
The strong link between climate and first incidence together with the presented model offers a tool to assess late blight incidence in future climates and shows that models used in decision support systems need to be checked and re-parametrized regularly to be able to capture changes in pathogen biology.
Delayed stigma receptivity in Collinsia heterophylla (Plantaginaceae): genetic variation and adaptive significance in relation to pollen competition, delayed self-pollination, and mating-system…
Phenotypic and genetic variation within populations in the timing of stigma receptivity and anther-stigma contact was substantial, although slightly less for the contact, and an among-genet phenotypic correlation between the traits was not found, indicating that each trait may respond independently to selection, and the trait association may be the result of correlational selection.
Pollen competition reduces inbreeding depression in Collinsia heterophylla (Plantaginaceae)
It is suggested that intermittent inbreeding, which leads to self‐fertilization in plants with genetic loads, may select for traits that enhance pollen competition.
Pollen Donor Identity Affects Timing of Stigma Receptivity in Collinsia heterophylla (Plantaginaceae): A Sexual Conflict during Pollen Competition?
The results suggest that female control on timing of stigma receptivity is not complete in this species, and fertilizations that occurred early during floral development resulted in fewer seeds than later fertilizations, possibly indicating a cost of lost control over the onset of receptivity.

If the response to phosphorus among pollen donors is more pronounced under natural conditions, variation in this environmental factor within populations has the potential to maintain some genetic variation in pollen tube growth rate even if this trait is constantly selected.
How does breeding system variation modulate sexual antagonism?
This work synthesizes how variation in breeding system can affect the evolution and expression of intra- and inter-locus sexual conflicts in plants and animals and predicts that, in hermaphrodites, SA traits will display lower levels of polymorphism and respond more quickly to selection.

Sexually antagonistic evolution caused by male–male competition in the pistil
It was found that high siring success of early arriving pollen competing with later‐arriving pollen was associated with high female fitness costs, consistent with an interlocus sexual conflict.

It is predicted that PRIs will play a role in future plant protection strategies in Solanaceae crops if they are combined with other means of disease control in different spatial and temporal combinations.
