Summary: In this study, the sex differentiation and related genes of S. chinensis were studied using SEM and RNA-seq. The results showed that male and female flowers of S. chinensis developed simultaneously, and sex may have been determined at an early stage in flower development. Plant hormones and sucrose played important roles in sex differentiation of S. chinensis, and certain transcription factor families were also involved.

Summary: Our study found that C. wolfii is functionally dioecious, with differences in ovule and anther development between staminate and pistillate flowers. There are no genetic or developmental barriers in the earlier stages of pollen recognition and pollen germination. However, despite producing a large number of aborted seeds, this species has low reproductive success and small population sizes.

Summary: This study describes the anatomical floral development of three species in the Mauritiinae subtribe using standard light microscopy techniques. It identifies three central moments in the development of pistillate and staminate flowers and suggests that Mauritiinae may have a hermaphrodite ancestor.

Summary: Andromonoecy, the presence of perfect and staminate flowers in the same individual, has evolved repeatedly in angiosperms. The smaller size and higher pollen production of staminate flowers enhance pollination success, even with limited resources.

Summary: The study of the inflorescence, floral structure, and ontogeny of the Chinese ashes provides insights into its unique floral structure and developmental basis, compared to the Sapindaceae family. The research reveals significant floral dimorphism in terms of differences in filament and style lengths, as well as the presence or absence of fruits. Additionally, the presence of empty stamen positions is inversely correlated with the sequence of petal initiation and delayed growth, suggesting a balance between petal and stamen initiation.

Summary: In this study, the regulatory mechanisms of floral initiation and floral organ development in strawberry were investigated. The GATA transcription factor gene, FaHAN, was found to play a crucial role in these processes. Overexpression of FaHAN delayed flowering, resulted in malformed floral organs, and caused abnormal fruit development.

Summary: A sodium alginate-based film incorporated with a Schisandra chinensis extract-natamycin complex was developed, which showed improved physical and functional properties compared to neat sodium alginate film. The film had reduced moisture content and water vapor transmission rate, increased opacity and elongation at break, and satisfactory antimicrobial activity. It also extended the shelf life of cucumbers and blueberries.

Summary: The floral morphology of Eriocaulon is highly diverse due to fusion, reduction, or loss of perianth parts. Nectariferous carpellodes originated first in staminate flowers, while petal glands and nectariferous branches in pistillate flowers originated independently through the transfer of function.

Summary: In this study, transcriptome analysis of Schisandra chinensis berries revealed an upregulation of the coniferyl alcohol biosynthetic pathway during postfruit development, which forms a transcriptional network with fruit ripening-related genes. Candidate genes involved in the regulation of schisandrin biosynthesis were also identified. These findings provide new insights into the production and accumulation of schisandrin and can be utilized to improve its content.

Summary: This study investigates the developmental morphology and anatomy of Rapateaceae, a plant family with unique inflorescence and gynoecium structures. The research found that this family lacks septal nectaries, but a bird-pollinated tribe within the family possesses a unique non-septal nectary.

Summary: Schisandra chinensis fruits, their extracts, and bioactive compounds have potent antioxidant and mitoprotective effects, exerting anti-inflammatory, antiviral, anticancer, and anti-aging properties. The polyphenolic compounds in S. chinensis are responsible for its antioxidant activities, which play a significant role in protecting cells under normal and pathological conditions.

Summary: Schisandra chinensis is a potential plant for production of nutrient supplements, but it can have allelopathic effects on other plants. The eco-toxicological properties of S. chinensis have not been verified in European ecosystems. In this study, Lemna minor was used as a model aquatic plant to test the impact of S. chinensis extract on the aquatic environment. The extract caused significant limitations in duckweed growth and photosynthetic performance at higher concentrations, and extreme toxicity at the highest concentration of 45 mg/L.

Summary: This study aims to understand the floral development and identify the ontogenetic pathways that lead to organ variation and andromonoecy in Mimosa species. The research reveals that the development of floral organs in Mimosa is synchronous but differs in the order of appearance. The merism variation in Mimosa is mainly due to the absence of organs in the perianth and androecium. The findings contribute to a better understanding of floral evolution and unstable organ merism in the mimosoid clade.

Summary: Through high-throughput DNA sequencing, it was found that fully mycoheterotrophic species of Burmannia are more specialized in their fungal associations than chlorophyllous species. Although many fungal species were shared by different Burmannia species, fully mycoheterotrophic species typically host species-specific fungal assemblages, indicating a preference for selected fungi.

Summary: The genus Phyllanthus is paraphyletic, with several genera nested within it. Differences in characters and taxonomic issues were found, leading to the recommendation of dividing Phyllanthus into several monophyletic genera.

Summary: Breakdown of self-incompatibility in sympatric populations of Hedyotis species is found to facilitate interspecific hybridization, with Hedyotis acutangula being both self- and interspecific compatible, while Hedyotis vachellii, H. bodinieri, and H. loganioides are self-compatible but interspecific incompatible. Hedyotis shiuyingiae, on the other hand, is strictly self- and interspecific incompatible. Pollen tube growth rate comparisons suggest that heterospecific pollen of certain species can compete with conspecific self-pollen in facilitating interspecific hybridization.

Summary: Evolutionary slowdowns in diversification have been observed in the Cirrhopetalum alliance, with the origin of Crassulacean acid metabolism (CAM) providing a short-term advantage. However, a subsequent slowdown in diversification may be due to the inability to keep up with changes in CO2 concentrations. Additionally, extinction rates in strong CAM lineages are higher than in C3 lineages, challenging the assumption that CAM is a key innovation in orchid diversification.
