Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

open access: yesAngewandte Chemie, Volume 138, Issue 36, 1 September 2026.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.

Sourdough fermentation as a modulator of nutritional quality in cereal‐based baked products

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Sourdough fermentation, an ancient food bioprocessing technology, has attracted renewed attention for its positive impact on the nutritional profile and sensory attributes of leavened baked products. This process relies on the symbiotic activity between lactic acid bacteria and yeasts, which leads to acidification, proteolysis, enzyme ...

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

open access: yesPest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Snake Gut Microbiota as a Source of Anti‐Inflammatory Probiotics: Isolation and Functional Characterization of Two Novel Strains

open access: yesIntegrative Zoology, EarlyView.
This study assessed the probiotic potential of intestinal microbiomes from five snake species using metagenomics and in vitro isolation, identifying two promising strains (Lactobacillus johnsonii DA0116 and Limosilactobacillus reuteri DA0218) through comprehensive screening.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

open access: yesInsect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

A cytochrome P450 gene, GmSUR2a, confers submergence tolerance and improves yield in soybean by modulating auxin homeostasis

open access: yesJournal of Integrative Plant Biology, EarlyView.
The key cytochrome P450 gene GmSUR2a enables soybeans to withstand destructive submergence stress. By lowering the level of the plant hormone indole‐3‐acetic acid, this gene improves soybean survival and increases field yield. It offers an important tool for breeding stress‑resilient soybeans, securing food production against extreme weather conditions.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

α‐1,3‐Glucan Is Required for Cell Wall Integrity and Full Virulence of Colletotrichum graminicola, but Not for Evasion of PAMP‐Triggered Immunity

open access: yesMolecular Microbiology, EarlyView.
Abbreviated Summary The role of the major fungal cell wall polymer α‐1,3‐glucan in plant infection is poorly understood. Deletion mutants of the maize anthracnose fungus Colletotrichum graminicola lacking all three α‐1,3‐glucan synthase genes differentiated severely distorted biotrophic hyphae in planta, and virulence was strongly reduced.

Characterization of carABpyrB operon and role of pyrE in Francisella novicida biofilm

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Pyrimidine biosynthesis links metabolism to biofilm regulation in Francisella novicida. During nutrient limitation, reduced pyrimidine availability shifts metabolism from uracil salvage to de novo synthesis, increasing biofilm formation. Mutants in carABpyrB exhibit uracil‐dependent growth defects and elevated biofilm:growth ratios, revealing ...
