Entomopathogenic nematode-associated microbiota: from monoxenic paradigm to pathobiome

Microbiome, 2020
Background The holistic view of bacterial symbiosis, incorporating both host and microbial environment, constitutes a major conceptual shift in studies deciphering host-microbe interactions. Interactions between Steinernema entomopathogenic nematodes and

Mixing and Matching of Hybrid Megasynthases is a Hub for the Evolution of Metabolic Diversity in Cyanobacteria

Angewandte Chemie International Edition, Volume 64, Issue 26, June 24, 2025.
Natural combinatorics: Evolutionary mixing and matching of three cyanobacterial biosynthetic gene clusters resulted in the emergence of minutumamides, a novel family of peptide‐polyketide hybrids. Retro‐evolutionary analysis led to the discovery of nostopeptolide KVJ3, an evolutionary ancestor that links nostopeptolide and minutumamide biosynthesis and

Effects of Xenorhabdus and Photorhabdus (Morganellaceae) on volatile composition of “Tempranillo” must and on Saccharomyces cerevisiae during alcoholic fermentation

Biological Control
Viticulture is a global activity producing over eighty million tonnes of grapes annually, 50 % used in winemaking. Traditional viticultural practices still rely on hazardous pesticides, posing environmental and health risks.

Two Distinct Hemolytic Activities in Xenorhabdus nematophila Are Active against Immunocompetent Insect Cells [PDF]

Applied and Environmental Microbiology, 2001
ABSTRACT Xenorhabdus spp. and Photorhabdus spp. are major insect bacterial pathogens symbiotically associated with nematodes. These bacteria are transported by their nematode hosts into the hemocoel of the insect prey, where they proliferate within hemolymph.

Xenorhabdus khoisanae SB10 produces Lys-rich PAX lipopeptides and a Xenocoumacin in its antimicrobial complex

BMC Microbiology, 2019
Background Xenorhabdus spp. live in close symbiosis with nematodes of the Steinernema genus. Steinernema nematodes infect an insect larva and release their symbionts into the haemocoel of the insect. Once released into the haemocoel, the bacteria produce

A functional genomic screen for evolutionarily conserved genes required for lifespan and immunity in germline-deficient C. elegans. [PDF]

PLoS ONE, 2014
The reproductive system regulates lifespan in insects, nematodes and vertebrates. In Caenorhabditis elegans removal of germline increases lifespan by 60% which is dependent upon insulin signaling, nuclear hormone signaling, autophagy and fat metabolism ...

Genome mining of Bacillus thuringiensis strain SY49.1 reveals novel candidate pesticidal and bioactive compounds

Pest Management Science, Volume 81, Issue 1, Page 298-307, January 2025.
This study identified novel genes responsible for producing putative pesticidal toxins, antimicrobial compounds, and plant growth‐promoting proteins, shedding light on the potential agricultural applications of the Bt SY49.1 strain. Abstract BACKGROUND Bacillus thuringiensis SY49.1 (Bt SY49.1) strain has promising insecticidal and fungicidal activity ...

Harnessing Gram‐negative bacteria for novel anti‐Gram‐negative antibiotics

Microbial Biotechnology, Volume 17, Issue 11, November 2024.
In this mini‐review, we highlight prominent examples of novel anti‐Gram negative natural products produced by isolated Gram‐negative bacteria that are currently in pre‐clinical development. Furthermore, we will provide insights into the considerations and strategies behind the discovery of these agents and their putative applications.

Natural products from Xenorhabdus and Photorhabdus show promise as biolarvicides against Aedes albopictus

Pest Management Science, Volume 80, Issue 9, Page 4231-4242, September 2024.
Entomopathogenic organisms are novel biopesticide sources. Xenorhabdus and Photorhabdus spp. are quite effective against Aedes albopictus larvae. Fabclavine can be developed into biolarvicides or used as a model to synthesize new compounds. Abstract BACKGROUND In the perpetual struggle to manage mosquito populations, there has been increasing demand ...
