Summary: This study investigated the genetic and phenotypic differences between two populations of the annual insect-pollinated plant Datura inoxia in Mexico. The results showed significant variations in outcrossing and selfing rates between the two populations, with Mapimi population favoring outcrossing and Canada Moreno population favoring selfing. Additionally, the study found a relationship between inbreeding depression and primary selfing rate in the Canada Moreno population.

Summary: There is a widespread association between selfing rate and floral size within and among taxa, but this association is not reflected at microevolutionary scales. The divergence in mating system among populations of Collinsia verna is consistent with their previously observed selection pressures, but the divergence in floral traits is not as expected.

Summary: This study compared the variation in floral traits of central and peripheral populations of the distylous Primula wannanensis, finding that late-opening flowers had significantly reduced flower size and weakened sex-organ reciprocity. Despite the reduced herkogamy, seed set remained high under pollinator-excluded conditions, supporting the hypothesis of delayed autonomous selfing evolution in marginal populations of distylous species.

Summary: The study revealed that perennial populations of Incarvillea sinensis in China tend to outcross more than annual populations, and this difference is maintained even in sympatric sites. Genetic differences in herkogamy between annuals and perennials play a key role in governing outcrossing rates, regardless of local ecological conditions. The maintenance of mating system and life history trait differentiation between the two populations likely results from correlated evolution in response to local environmental conditions.

Summary: The genetic basis of selfing rate evolution in plant populations is still unclear. This study investigates the genetic basis of selfing rate evolution using population genetic models. The results show that selfing modifiers differ from mating-unrelated loci in their phenotypic effects and the selection coefficient depends on the background selfing rate. Moreover, the evolution of selfing involving multiple modifier loci is more likely when selfing is controlled by few large-effect rather than many slight-effect modifiers.

Summary: The shift from outcrossing to self-fertilization is a common evolutionary transition in flowering plants. Selfing species share similar reproductive traits, known as the selfing syndrome. Recent studies have used population genomics and high-throughput sequencing to uncover the molecular and genetic basis for the evolution of the selfing syndrome in several plant genera. These studies have identified specific genes and mutations responsible for selfing syndrome traits, and have investigated the relationship between selfing and interspecific pollen transfer.

Summary: When studying dioecy and hermaphroditism, the consideration of pollen risks is crucial. Dioecy prevails in landscapes with abundant conspecific pollen donors or recipients, while hermaphroditism is more common in landscapes with low conspecific pollen or abundant heterospecific pollen.

Summary: The study found that in a bird-pollinated herb, despite high outcrossing rates, paternal diversity was surprisingly low. Visitation rates from nectar-feeding birds were low and pollen loads were minimal, leading to the observed decrease in paternal diversity.

Summary: The transition from outcrossing to selfing is a common evolutionary trend in flowering plants. The presence of selfing syndrome-related floral traits is more evident in populations with a higher selfing rate, but these traits are subjected to weak selection in populations with different selfing rates. Selfing provides reproductive assurance for populations with low pollinator service, and the selective pressures on floral traits related to pollinator attraction and specialization may not change significantly with the evolution of selfing, highlighting the independent influences of biotic and abiotic pressures and the mating system on morphological traits.

Summary: This study aims to determine if monoecious plants can effectively avoid self-interference and promote the evolution of monoecy under the service of pollinators. The results show that pollinator-mediated self-interference significantly reduces selfing, providing potential dynamics for the maintenance and evolution of monoecy.

Summary: Autonomous selfing, known as pollen tube shower, was observed in Bertolonia plants with poricidal anthers. The movement of flower parts during post-anthesis events led to the transient absence of herkogamy, promoting delayed selfing. This mechanism ensures reproductive success and reproductive assurance for flowers that have not been pollinated.

Summary: Theoretical models were developed to propose a new mechanism for enhancing mixed mating in hermaphroditic plants. The study found that mixed mating can be maintained if there is among-parent variation in early-acting inbreeding depression. It was also discovered that producing a moderate number of embryos is advantageous to reduce waste of resources.

Summary: This study revealed the reproductive characteristics of L. oblata, a critically endangered species endemic to cliffs in North China, providing insight into its endangerment and suggesting conservation strategies. L. oblata has highly pollinator-dependent self-fertilization as part of a mixed mating system. Floral features such as low-flowering synchrony, asynchronous anthers dehiscence, and high duration of stigma receptivity, improve pollination efficiency in the case of low pollinator service.

It identifies Mediterranean and Carpathian forests as glacial refugia and central Europe and Italy as important genetic sources during postglacial recolonization. The study also reveals the association between adaptive single-nucleotide polymorphisms and temperature, elevation, and precipitation.

Summary: Insect responses to volatile organic compounds (VOCs) emitted by bacteria vary among and within different trophic levels. The concentrations of VOCs differ between bacterial strains, and correlations between the concentration of specific VOCs and the behavior of primary parasitoids and hyperparasitoids vary. This study provides insights into the potential use of VOCs for developing semiochemical-based strategies for biological aphid control.

Summary: The decline of pollinators may have negative effects on ecosystems and ecosystem services. This study investigates the impact of pollen diversity and composition on reproductive success and fitness of Bombus terrestris colonies. The results suggest that plant diversity may not be a good predictor of colony fitness, and that vegetation composition and differences in pollen quantity and quality are more important.

Summary: Microorganisms living in and on macroorganisms can produce volatile compounds that can help carnivorous enemies locate their host or prey. Parasitism by parasitoid wasps can alter the microbiome and odour of their caterpillar host, which can affect interactions with other insects. This study analyzed the odours and microbiome of cabbage white caterpillars in relation to parasitism by endoparasitoid wasps and found that parasitism led to the production of characteristic volatile compounds and significant changes in the caterpillar's microbiome. The preference of a hyperparasitoid was correlated with the presence of the external microbiome.

Summary: Endophytic fungi can protect plants against stresses and promote plant growth. This study evaluated the effects of root inoculation with three entomopathogenic fungi on sweet pepper growth. Results showed that all three fungi enhanced plant growth, and effects varied depending on cultivar and fungal strain. The strongest effects were observed in the cultivar IDS RZ F1, particularly when inoculated with C. fumosorosea.

Summary: This study investigated the effects of different species of plant-beneficial fungi on plant nutrient composition and resistance against zoophytophagous predators, and assessed whether these effects are mediated by plant cultivar. The results showed that plant nutrient composition is mainly determined by cultivar, but is also affected by fungal treatment. Fungus-inoculated plants showed significantly less feeding damage by N. tenuis compared to control plants, but the effects depended on the cultivar and fungal strain used.
