Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

open access: yesPest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

open access: yesPest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Systematic prioritization of candidate genes in camptothecin biosynthesis using multi‐omics and deep learning

open access: yesThe Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Camptothecin (CPT), a plant‐derived monoterpene indole alkaloid first identified in Camptotheca acuminata, is a drug precursor widely used for cancer chemotherapeutics. However, the full set of genes responsible for CPT biosynthesis remains unclear, hindering efforts to elucidate the complete pathway or establish biosynthetic production of CPT

Enhancing IR‐MALDESI MSI Spatial Resolution Through Beam Constriction With a Ring‐Actuated Iris

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Infrared matrix‐assisted laser desorption electrospray ionization (IR‐MALDESI) mass spectrometry imaging (MSI) enables label‐free, spatially resolved molecular analysis of biological tissues under ambient conditions. While improving spatial resolution is important for mapping fine tissue structures, mid‐infrared (IR) lasers are ...

ω‐Hydroxyacid Dehydrogenases From Clostridium viride: Iron‐Containing Biocatalysts With Biotechnological Potential

open access: yesChemBioChem, Volume 27, Issue 16, 27 August 2026.
ω‐Hydroxy and ω‐oxo acids are precursors to lactones, polyesters, and nylon‐6, yet selective interconverting enzymes remain scarce. Clostridium viride supplies two iron alcohol dehydrogenases: Cvir‐Hbd2, restricted to C4, and the genomic singleton Cvir‐Hvd, spanning C5–C12 substrates.

Fragmentation of Vancoresmycin Reveals a Strong Dependence on Global Molecular Architecture for Antibacterial Activity

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Fragmentation of the natural product vancoresmycin reveals an essential role of global architecture for biological potency. Vancoresmycin is a structurally complex tetramic‐acid‐containing natural product with potent activity against Gram‐positive bacteria, yet its structure–activity relationships remain poorly defined.

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective

open access: yesAdvanced Science, Volume 13, Issue 47, 24 August 2026.
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

Discovery of VEGFR‐2 Inhibitors From Leonurus japonicus via Integrated Genetic Authentication, Molecular Networking, and In Silico Analysis

open access: yesArchiv der Pharmazie, Volume 359, Issue 8, August 2026.
Genetic authentication of Leonurus japonicus was confirmed using ITS sequencing. UHPLC‐MS/MS‐GNPS analysis and isolation led to a new labdane diterpenoid (1) and known compounds (2–6), with anti‐angiogenic activity validated by EPC assays and VEGFR‐2 docking studies.
