Metabolites of Xenorhabdus bacteria are potent candidates for mitigating amphibian chytridiomycosis
AMB Express, 2023 Chytridiomycosis, caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd), has caused extreme losses in amphibian biodiversity. Finding bacteria that produce metabolites with antifungal properties may turn out to be invaluable in the fight ...

Structure and Biosynthesis of Xenoamicins from Entomopathogenic Xenorhabdus [PDF]
Chemistry – A European Journal, 2013 AbstractDuring the search for novel natural products from entomopathogenic Xenorhabdus doucetiae DSM17909 and X. mauleonii DSM17908 novel peptides named xenoamicins were identified in addition to the already known antibiotics xenocoumacin and xenorhabdin. Xenoamicins are acylated tridecadepsipeptides consisting of mainly hydrophobic amino acids.

Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe
Chemistry – A European Journal, Volume 32, Issue 11, 16 March 2026.The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Colonial and Cellular Polymorphism in Xenorhabdus luminescens [PDF]
Applied and Environmental Microbiology, 1989 A highly polymorphic Xenorhabdus luminescens strain was isolated. The primary form of X. luminescens was luminescent and nonswarming and produced a yellow pigment and antimicrobial substances.

New Plant Protection, Volume 3, Issue 1, March 2026.In this research, GXP serves as a potent synergist for Metarhizium anisopliae in controlling cotton aphids. Its synergistic effect is achieved through two key mechanisms: first, by downregulating melanization protease 1 expression to inhibit phenoloxidase activity, thereby suppressing melanization; second, by reducing hypoxanthine levels, which ...

Immune interactions between Drosophila and the pathogen Xenorhabdus
Microbiological Research, 2020 Deciphering host innate immune function and bacterial pathogenic tactics require a system that facilitates both facets of host-pathogen interactions. In recent years, a model that becomes established in dissecting mechanisms of host antibacterial immune response through probing with a potent bacterial pathogen involves the fruit fly Drosophila ...

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective
The FEBS Journal, Volume 293, Issue 6, Page 1801-1817, March 2026.Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.Metatranscriptomic analysis of Centaurea cyanus revealed diverse plant‐associated viral and bacterial sequences in herbicide‐susceptible and ‐resistant biotypes. While novel partitiviruses occurred independently of resistance status, differences in bacterial community composition may suggest a potential role of the plant microbiome in responses to ...

Molecular Ecology, Volume 35, Issue 1, January 2026.ABSTRACT Intensification of insecticide resistance in malaria vectors is undermining efforts to sustain control strategies. The evolutionary features underlying such exacerbation in major vector such as Anopheles funestus are only partially understood.
