Summary: Gesneriaceae, a pantropical plant family with diverse growth forms and floral morphology, has had its systematics improved with the development of a specific gene capture kit targeting 830 single-copy loci. This allowed for the resolution of phylogenetic relationships within the family, providing high support for major lineages and high resolution within recent radiations. This molecular resource opens new perspectives for studying Gesneriaceae phylogeny at different taxonomical levels and understanding the factors underlying the diversification of this plant group.

Summary: This study investigated the evolutionary history of Henckelia, a genus of plants in the Gesneriaceae family, using whole-genome shotgun sequencing and cytological data. The study revealed that hybridization and polyploidization are common processes in this genus, and identified several potential hybridization and polyploidization events. Additionally, the taxonomic classification of this genus was revised based on the findings.

Summary: A taxonomic synopsis of the Philippine Cyrtandra genus is presented, accepting 98 species endemic to the country. Lectotypes or neotypes are designated for all names, except for six with missing original material. Two replacement names are proposed and a look-up table is provided for easy referencing.

Summary: This study used plastid phylogenomics to explore the relationships within the Trichosporeae tribe. It found that Hemiboea has diverse morphology, with plastome lengths ranging from 152,742 bp to 153,695 bp and GC contents ranging from 37.2% to 37.8%. The study also identified 13 hypervariable regions that could be potential molecular markers for species identification.

Summary: Homology is essential in comparative analysis of nectar guide patterns, with the study proposing a method to define a homologous region of interest (ROI) for alignment and analysis. Qualitative and quantitative analyses revealed significant associations between nectar guide patterns and pollination types, with proximal and distal modes showing the strongest links to pollination types.

Summary: Resurrection plants have the unique ability to survive in dry and freezing conditions. The response of the photosynthetic apparatus and the role of protective proteins in freezing tolerance were investigated. Freezing-induced dehydration inhibited photosynthetic activity, but plants were able to recover their photosynthetic activity during the recovery process.

Summary: The genus Didymocarpus is widely used in traditional medicine in Asian countries and has shown various pharmacological activities, including antiurolithiatic, nephro-protective, antimicrobial, anticancer, antidiabetic, cytotoxic, wound healing, and antioxidant activities. However, further studies on the pharmacology and toxicology of these species are needed to ensure their safety, efficacy, and quality.

Summary: A new plant species, Oreocharis xieyongii, is described from Hunan Province, central China. Its distinctive features include a purple zygomorphic corolla with longer adaxial lobes and exserted stamens, which set it apart from other Oreocharis species. Phylogenetic analysis reveals its placement within the Oreocharis genus. Comparative analysis with similar species highlights the unique traits of O. xieyongii. The study provides both morphological and molecular evidence supporting the recognition of O. xieyongii as a new taxon.

Summary: In this study, the complete chloroplast genomes of twelve Paraboea species were sequenced and analyzed, revealing the genomic structure and composition, as well as potential molecular markers. In the phylogenetic tree, all Paraboea species formed a distinct clade, confirming their monophyly. Additionally, genes related to photosynthesis and protein synthesis were found to play crucial roles in the adaptability of Paraboea to diverse karst environments.

Summary: A phytochemical investigation on Paraboea rufescens resulted in the isolation of 17 compounds, including nine phenylethanoid glycosides, two steroids, two triterpenoids, two dihydroflavones, and two organic acids. The structures of these compounds were determined through spectroscopic analysis. This study provides the first report on compounds from P. rufescens and discusses the chemotaxonomic significance of P. rufescens among other Gesneriaceae species.

Summary: Two new ursane-type triterpenes, eburnealactones A and B (1 and 2), one new flavonoid, eburneatin A (6), and one new phenylethanoid glycoside, chiritoside D (7), were isolated from the whole plant of Primulina eburnea. The structures of these compounds were determined by extensive spectroscopic analysis (IR, UV, NMR, and HR-ESI-MS). The cytotoxic activities of all compounds were evaluated, with compound 1 showing significant activity against MKN-45 and 5637 cell lines, and compound 6 showing moderate activity against multiple cell lines. Compound 5 exhibited moderate activity against A549 cell lines.
