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: 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: Increased self-fertilization can provide reproductive assurance and decrease fitness due to deleterious mutations when plant populations experience pollen limitation. This study used eco-evolutionary models to examine the conditions in which higher self-fertilization through plasticity and/or evolution can rescue populations from pollen limitation. The results showed that rescue is most likely to occur at an intermediate level of selfing rate increase, with plasticity being more likely than evolution. The study emphasizes the importance of plasticity in plant population rescue and provides insights for understanding the evolution of mating system plasticity in future research.

Summary: This study investigates the impact of an invasive alien plant on the visitation rate of nectar-feeding bird pollinators to a native plant, finding that Banksia speciosa can attract sugarbirds away from native Protea compacta. This may have implications for the reproductive success of the native plant in the long term.

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: 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.

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: 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: The Qinghai-Tibetan Plateau and the Hengduan Mountains Region are biodiversity hotspots, where climate change and habitat heterogeneity may have influenced the evolution of plant adaptive strategies. Through studying plant-pollinator interactions, it was found that bees were the main pollinators, with factors such as pollen limitation and self-compatibility impacting plant adaptive strategies.

Summary: The study showed that delayed autonomous selfing (DAS) in Salvia umbratica can increase fruit and seed set rates, particularly in the absence of pollinators. Immediate pollination after flower opening can also lead to high fruit and seed set rates, but with lower effectiveness if pollen load is reduced. Flower longevity in S. umbratica varies to optimize reproductive output based on the availability and effectiveness of pollinators.

Summary: In haploid species, selfing lacks the benefits from recombination and is similar to asexual reproduction at the genetic level. However, homothallism (self-compatibility) has evolved multiple times in fungi. Two hypotheses have been proposed for the evolution of homothallism: reproductive assurance and population-level compatibility. In this study, by using the fission yeast Schizosaccharomyces pombe, the researchers found that homothallism by mating-type switching increased mating success but reduced outcrossing, suggesting that the recurrent evolution of haploid self-compatibility is likely driven by selection for mating assurance rather than enhancing outcrossing potential.

Summary: The staggered arrangement and sequential dehiscence of anthers in the didynamous stamens of Brandisia hancei facilitate reproductive fitness by prolonging pollen presentation and promoting delayed self-pollination, ultimately leading to higher seed production.

Summary: Our study found that supplementing with pollen significantly increased seed set per flower, indicating pollen limitation in this species. Additionally, hand cross-pollination resulted in greater seed set in the restored habitat compared to the fragmented environment. More Apis mellifera visits were recorded in the restored habitats, potentially explaining the difference in seed production between fragmented and restored habitats.

Summary: This study gathered existing information on the reproductive biology, megagametophyte development, and apomixis of Malpighiaceae species. It found limited and fragmented knowledge about the reproductive biology of these species and emphasized the need for further research on inter-population variations to understand their evolutionary traits and mechanisms of population differentiation.

Summary: Iris verna, an endangered plant species in Pennsylvania, was found to be self-compatible but requires pollinators for pollen transfer. Our study revealed that pollinators are a significant limiting factor for sexual reproduction in this species, and ants were identified as potential seed dispersers.

Summary: Service-learning is an experiential learning approach that connects course content with community needs. This study incorporated service-learning into a plant biology course and examined the differences in plant biology knowledge, classroom community connections, and self-efficacy for environmental action between service-learning participants and non-participants. The findings showed that service-learning students had a slightly increased sense of community with their peers but did not perceive a higher ability to be agents of social change.
