Amino Acid Elicitation for Improved Hypocrellin A Biosynthesis in Shiraia bambusicola Under Elevated Fermentation Temperature

Hypocrellin A (HA) is a perylenequinone photosensitizer produced by Shiraia bambusicola during submerged fermentation, but its accumulation during submerged fermentation remains limited by low biosynthetic efficiency. Building on our previous finding that 32 °C increased HA accum...

A self-assembled Dendrobium polysaccharide hydrogel with anti-aging activity via the FOXO signaling pathway

Faced with the complexity and diversity of skin aging, it is critical to investigate multi-target synergistic anti-aging products. Herein, a novel composite hydrogel with anti-aging activity was developed based on Dendrobium polysaccharide, hyaluronic acid (HA), and nicotinamide...

1,2- seco -Bicyclic Polyprenylated Acylphloroglucinols as Isoform Selective Inhibitors of T-Type Calcium Channels

Abstract Hyreptaones A–E (1–5, respectively), five undescribed 1,2-seco-bicyclic polyprenylated acylphloroglucinols (BPAPs), were discovered in Hypericum reptans. 1–3 constitute the first 1,2-seco-BPAPs originating from rare 3,3-diisoprenylated BPAPs. 4 and 5 possess a spirocycli...

Large‐scale nuclear and plastid phylogenomic analyses inform an updated Angiosperm Phylogeny Group classification: APG V

Abstract We present here a revision of the APG classification that considers the extensive recent analyses of hundreds of nuclear and plastid genes for many angiosperm species. Although previous versions of the APG classification were largely based on uniparentally inherited mark...

Discovery and Semisynthesis of Arthritacins A–J—Terpestacin-Derived Sesterterpenoids from the Plant Endophytic Fungus Arthrinium sp. HS66

Arthrinium species are promising producers of terpenoids with diverse architectures and noteworthy pharmacological properties. In this work, ten undescribed terpestacin-type sesterterpenoids, arthritacins A–J (1–10), together with five known analogues (11–15), were obtained from...

Coordination of cyclic electron flow and alternative electron sinks adjusts photosynthetic regulation in maize under fluctuating light during combined heat and drought stress

Field-grown maize is frequently exposed to fluctuating light (FL) combined with heat and drought during summer, yet the underlying photosynthetic regulatory mechanisms remain poorly understood. We examined chlorophyll fluorescence, the P700 redox state, and electrochromic shift s...

Fruit- and Vegetable-Derived Exosome-like Nanovesicles: A Review

Fruit- and vegetable-derived exosome-like nanovesicles (FV-ELNs) are nanovesicles characterized by a lipid bilayer membrane that encloses a diverse array of biologically active constituents, including proteins, lipids, nucleic acids, and small-molecule bioactive compounds. FV-ELN...

Characterization and phylogenetic analysis of the mitochondrial 12S rRNA gene sequences of Aphaniops dispar

The Arabian killifish ( Aphaniops dispar ) is a resilient freshwater species capable of surviving extreme environments, making it a valuable model for studying evolutionary adaptation in challenging environments. This study provides baseline genetic information of A. dispar popul...

Systemic reorganization of the photosynthetic apparatus underlies acclimation to nitrogen starvation across leaf ages in barley

Nitrogen (N) deficiency severely constrains global crop productivity, yet acclimation strategies in cereals remain incompletely understood. Hydroponically grown barley ( Hordeum vulgare ) plants were subjected to N starvation for 14 days. Photosynthetic properties were monitored...

Enterotype signatures of multi-stressor exposure inform conservation strategies for mountain bumblebees of the subgenus Pyrobombus

Bees often exhibit gut microbiome-defined enterotypes impacting their health and pollination services. Bumblebees, keystone pollinators in montane and agriculture ecosystems, face significant population declines might linked to gut parasites, pathogens, and antibiotic exposure; h...

β-carboline derivative Z86 alleviates pulmonary fibrosis via suppressing TGF-β/Smad signaling

Idiopathic pulmonary fibrosis (IPF) is characterized by aberrant fibroblast proliferation and excessive expression and deposition of extracellular matrix (ECM) by myofibroblasts, ultimately resulting in progressive and irreversible disorder or even loss of the pulmonary function....

Himalamintha (Lamicaeae, Nepetoideae, Mentheae, Menthinae) a new genus from the Himalayan region

Abstract Himalamintha is described as a new genus in subtribe Menthinae characterized in first place by a calyx that is tubular and only weakly bilabiate, not sigmoid and distinctly bilabiate. The new genus contains 6 rather poorly known species occuring throughout the Himalayan...

Plant species identification by genome skimming across the vascular plant tree of life

Summary Accurate species identification is essential for biodiversity conservation and sustainable use, yet standard plant DNA barcoding often fails to achieve species‐level resolution. We present a large‐scale empirical evaluation of genome skimming as a tool to improve plant sp...
