Summary: The Vitaceae family, located in the basal lineages of Rosids, consists of sixteen genera and 950 species, primarily tropical lianas. Seed shape in this family is varied and has been classified into ten groups based on their similarity to geometric models. Three groups correspond to previously described models shared with the Arecaceae, while the remaining seven groups include general models and specific shapes found in particular genera within the family. The application of geometric models for seed description and shape quantification in the Vitaceae family is discussed.

Summary: The pollen of Piperales varies in size, with consistent aperture types and exine ornamentation within genera. Orbicules, minute sporopollenin granules, may be a possible ancestral characteristic of Piperales. The cluster analysis results using palynological characters are generally congruent with the known molecular phylogeny of Piperales.

Summary: Causonis, a widely distributed genus in tropical, sub-tropical, and temperate regions from Asia to Australia, was confirmed to be monophyletic based on both chloroplast and nuclear gene data. The study identified 16 species and 4 varieties within the genus, including two new species. The evolutionary trends and relationships among major clades of Causonis were well-supported by the chloroplast data.

Summary: The study examined pollen grains from 92 genotypes of Bougainvillea, finding a wide range of shapes, sizes, and characteristics in the grains. Different genotypes exhibited varying patterns in pollen morphology and germination capacity, with germinated pollen being larger than non-germinated pollen due to nonuniform grain size distribution.

Summary: In this study, a high-quality chromosome-scale genome assembly and annotation of Tetrastigma hemsleyanum were presented. Gene duplication and amplification were found to contribute to the increase in genome size of this species. The divergence of two intraspecific lineages was dated and showed differential gene expression. This study provides valuable genomic resources for future studies in the evolutionary, ecological, and functional genomics of T. hemsleyanum and related species.

Summary: Pollen morphology of Asteraceae has been mapped onto a phylogenomic tree, revealing shifts and trends in the evolution of the family. The ancestral Asteraceae pollen grains possessed microspines and a nonlayered exine, similar to the oldest fossils discovered. The most recent common ancestor of Asteraceae had a layered sexine, except for the sister clade Barnadesieae. Pollen characters have varying levels of phylogenetic structure and can be used to identify fossil specimens and explore character evolution.

Summary: The present study investigated pollen morphology and viability of four Ocimum L. species, revealing that O. basilicum had the highest pollen viability and germination rate, while O. sanctum had the lowest viability. The highest pollen germinability for all four Ocimum species was observed at -20 degrees Celsius. This research could aid in taxonomic identification of Ocimum species and be utilized in conservation efforts and improvement through cross-hybridization breeding programs.

Summary: This study investigates the flora and vegetation of the river estuaries in Southern Oman, focusing on the plants growing on different substrates. The analysis of surface soil samples provides insights into the pollen diffusion and representation of these plants in the current pollen rain. The pollen records offer a general picture of the flora and vegetation in the area and are important for the interpretation of pollen records from ancient soils.

Summary: Pollen morphology and pollen viability are significant for plant taxonomy classification, with pollen polar length being the decisive characteristic to distinguish subsections in section Moutan. The differences in pollen viability also play an auxiliary role in the classification of tree peony.

Summary: This study quantitatively evaluated the morphological characteristics of Linum species pollen grains in Mexico. Statistical values of different pollen characteristics were reported, including polar axis, equatorial axis, shape, polar area, exine thickness, sexine thickness, nexine thickness, and height and diameter of ornamental pollen elements. The study found that the pollen grains had a prolate-spheroidal to subprolate shape, were tricolpate, and had sculptured exine with bacula, clavae, gemmae or spines. Principal component analysis revealed that five characters explained the highest percentage of variance between species. Cluster and discriminant analyses classified some of the species into three groups and differentiated three of them based on their morphology. Palynological traits proved to be a convenient tool for identifying Linum species.

Summary: In this study, pollen grains of 16 species of Campomanesia were analyzed using light and scanning electron microscopy. Heat map and multivariate regression tree analyses were performed to identify differences among species based on pollen morphology. The results showed that pollen morphology can be used as a reliable tool to distinguish different species of Campomanesia.

Summary: This study aimed to investigate the feasibility of using pollen grains as biomarkers of atmospheric transport between South America and Antarctica. Palynological analysis of snow samples collected in 2005 revealed the presence of spores and pollen grains from South America. The use of the Hybrid Single-Particle Lagrangian Integrated Trajectory model showed that the Andes serve as a heat source for pollen transport, confirming the feasibility of using pollen grains as biomarkers.

Summary: In this study, it was found that Chrysoperla externa faces challenges in foraging for pollen due to differences in pollen accessibility and morphology. The experiment showed that Cajanus cajan and F. macrophylla pollen were not consumed by Chrysoperla externa. Overall, Chrysoperla externa preferred pollen from the Poaceae family over the Fabaceae family.
