Summary: Bees produce different types of vibrations, including buzz pollination, through vibrations. Bees can control the characteristics of buzz pollination by adjusting the biomechanical properties of their thorax, in order to optimize energy use and pollen collection.

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: In Jasminum malabaricum, the long-styled morph had higher total pollen load while the short-styled morph had a higher inter-morph pollen fraction, but fruit set did not differ between morphs. Higher herkogamy and reciprocity may lead to increased inter-morph pollen deposition and reproductive success. Population-specific patterns suggest that local environmental factors determine the relative functional importance of herkogamy and reciprocity.

Summary: Research has shown that stamen appendages play a crucial role in transmitting vibrations and ensuring optimal pollen release in buzz-pollinated flowers, while their absence does not alter bee pollination behavior. This highlights the importance of connective appendages in the reproductive success of plants that rely on buzz-pollination.

Summary: GPI-APs play important roles in the interactions between pollen/pollen tube and pistil tissues, affecting pollen germination on the stigma, pollen tube growth in the transmitting tract, pollen tube guidance to the ovule, and pollen tube reception in the embryo sac.

Summary: Magnolia soulangeana 'Hongyun' is an ornamental tree with attractive shape and abundant flowers. Its breeding system is partially self-compatible, outcrossing, and depends on pollinators. 'Hongyun' presents a mass-flowering pattern with secondary opening and closing in the flowering process.

Summary: The joined anther cones in buzz-pollinated species have been found to cause increased vibrations and pollen release. The development of anther fusion is independent across different species and genetic mechanisms, and the functional significance of joined anther cones needs further investigation.

Summary: The study evaluated the progamic phase of fertilization and fruit set in four European plum cultivars in Western Norway, showing different adaptability of both recipient and donor cultivars to specific ecological conditions. The pollinizers Victoria, Opal and C. Lepotica were proven to be very good pollinizers for certain cultivars, while cultivars Opal, R. E. Prolific and Mallard were considered excellent pollinizers for Edda under certain temperature conditions.

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: Barbaretta aurea exhibits dimorphic enantiostyly and its flowers are specialized for pollination by syrphid flies. This species is fully self-compatible and relies on pollinator visits for seed production. This study contributes to our understanding of the evolutionary biology and pollination strategies of flowers.

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: The study found that segregating the different varieties of faba beans in blocks with a distance of more than 150 meters can limit the outcrossing rate to below 0.5%, despite the volatile and unpredictable nature of bee flights.

Summary: This study investigated the floral biology and pollination strategy of Aristolochia bianorii, an endemic plant species in the Balearic Islands. It was found that the species exhibits both autonomous self-pollination and cross-pollination, with Oscinomorpha longirostris flies being the main pollinators. The study showed that reproductive success depends on cross-pollination, while autonomous self-pollination serves as a backup mechanism in the potential absence of pollinators.

Summary: Miconia is a large plant genus in the Neotropics, and its taxonomy is complex. This study reconstructed the phylogeny of the Miconia discolor clade and proposed a new infrageneric classification. The study also investigated the evolution of morphological characters and the biogeographic history of the clade.

Summary: A comparative study on the stamens of Melastomataceae species revealed notable variations in their merosity, morphology, and connections. The delay in stamen development may be due to the requirement of a pre-existing space for their growth. The diversity of stamens can largely be explained by the formation of the connectives and their appendages.

Summary: The asymmetric pattern in species richness is a notable feature across different lineages and geographic regions. This study found that depauperon lineages in the Melastomataceae family have limited dispersal ability, dependency on water for dispersal, and restricted niche, which make them more susceptible to the threats of climate change and habitat fragmentation. Therefore, it is necessary to prioritize the conservation of these unique species groups.

Summary: Previous molecular phylogenetic analyses showed a strong correlation between species distribution and floral traits in the endemic genus Bertolonia in the Brazilian Atlantic Forest. The genus is divided into three clades based on their distribution. A rare delayed selfing mechanism, pollen tube shower (PTS), was found in one clade, but its prevalence in other clades was unknown. In this study, we investigated two other species and examined herbarium specimens for evidence of floral traits related to autonomous selfing mechanisms. We found that both species produced seeds through PTS and observed the occurrence of PTS in other species as well. Taxonomic data indicated the absence of herkogamy but the presence of post-anthesis petal closure and corolla persistence, all traits associated with PTS. This study provides empirical evidence and descriptions of floral traits that indicate the predominance of autogamy in the genus Bertolonia, which is uncommon in the family Melastomataceae.

Summary: In this study, two new species of the Neotropical genus Myrcia, Myrcia capixaba and M. forzzae, are proposed, described, and illustrated. Both species belong to the Aguava section of Myrcia and exhibit distinct morphological characteristics from other species in the section. Myrcia capixaba is found in the Atlantic Forest of Espirito Santo and possesses unique features such as dibrachiate trichomes on various plant structures and broadly elliptic to ovate leaves with faint secondary venation. Myrcia forzzae occurs in the Amazon Forest of Mato Grosso and differs from M. gigas in terms of internode length, trichome coverage on vegetative branches and inflorescence rachises, and presence of trichomes on the calyx lobes.

Summary: Based on our study of 16 Melastomataceae species, we found that stamen heteromorphism in pollen flowers is associated with functional and morphological differences at the pollen grain level. Pollinating anthers are larger and produce more and higher-quality pollen grains, while the feeding anthers are smaller. In addition, there are differences in pollen exine ornamentation in some species. Overall, our findings support the division of labour hypothesis.
