Cytotoxic Evaluation and Elucidation of Dammarane-Type Triterpenoids Isolated from the Exocarp of Aglaia cucullata (Meliaceae).
Aglaia cucullata is a mangrove plant with a tropical Asian distribution. It is used as traditional medicine for the treatment of diarrhea, inflammation, skin diseases, and heart diseases. Several compounds isolated from A. cucullata have demonstrated cytotoxic activity against various human cancer cells. Cancer therapies such as surgery, chemo-, and...Purnama, ... ; Anjari, Intan Hawina ; Farabi, Kindi ; Runadi, Dudi ; Mayanti, Tri …

Evolution of Seed Dispersal Modes in the Orchidaceae: Has the Vanilla Mystery Been Solved?
Orchid seeds are predominantly wind-dispersed, often developed within dry, dehiscent fruits that typically release millions of dust-like seeds into the air. Animal-mediated seed dispersal is a lesser-known phenomenon in the family and predominantly occurs in groups belonging to early-diverging lineages bearing indehiscent, fleshy fruits with hard, rounded, dark seeds. In... -

Online tree expansion could help solve the problem of scalability in Bayesian phylogenetics.
Bayesian phylogenetics is now facing a critical point. Over the last 20 years, Bayesian methods have reshaped phylogenetic inference and gained widespread popularity due to their high accuracy, the ability to quantify the uncertainty of inferences and the possibility of accommodating multiple aspects of evolutionary processes in the models that...Truszkowski, Jakub ; Perrigo, Allison ; Broman, David ; Ronquist, Fredrik ; Antonelli, Alexandre

Widespread Support for a Global Species List with a Formal Governance System.

Evolution of pollen grain morphology in Amorimia and allies evidences the importance of palynological apomorphies and homoplasies in Malpighiaceae systematics.
– Pollen grain morphology is an important morphological character for aiding the systematics of flowering plants. For Malpighiaceae, only a single unpublished palynological study has comprehensively sampled ca 60 of this family’s 75 currently accepted genera. To test the systematic relevance of pollen morphology in and allies, we characterised the... -

Molecular phylogenetics of Maranta (Marantaceae: Zingiberales): non-monophyly and support for a wider circumscription.
Neotropical Maranta has repeatedly emerged as non-monophyletic in molecular phylogenetic studies, but no taxonomic changes have been proposed due to previous weak support for the main clades and overall sparse taxonomic sampling. Our study includes a phylogenetic hypothesis strictly based on molecular evidence, using nuclear ribosomal (nrITS) and plastid (rps16,... -

Do Ectomycorrhizal Trees Select Ectomycorrhizal Fungi That Enhance Phosphorus Uptake under Nitrogen Enrichment?
Globally, forests are impacted by atmospheric nitrogen (N) deposition, affecting their structure and functioning above and below ground. All trees form mutualistic root symbioses with mycorrhizal fungi. Of the two kinds of mycorrhizal symbioses of trees, the ectomycorrhizal (EcM) symbiosis is much more sensitive to N enrichment than the arbuscular...Kuyper, Thomas W. ; Suz, Laura M.

The lower figure of nine macrospecies is based primarily on seeking small but reliable discontinuities in DNA ‘barcode’ regions, an approach... -
