Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling

open access: yesAngewandte Chemie Novit, Volume 2, Issue 1, March 2026.
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Aspergillus conicus Endophyte Improves the Development of Eucalyptus camaldulensis Seedlings In Vitro

open access: yesJournal of Basic Microbiology, Volume 66, Issue 3, March 2026.
ABSTRACT Fungi of the genus Aspergillus promote plant growth and resistance, enhance nutrient uptake, protect plants against pathogens, and increase tolerance to environmental stress. We examined the symbiosis between Aspergillus conicus and seedlings of Eucalyptus camaldulensis, a forest species widely grown in Brazil for its valuable wood and ...
