Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo [PDF]
Pest Management Science, Volume 82, Issue 4, Page 3603-3612, April 2026.The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor‐like lectin [PDF]
The FEBS Journal, Volume 293, Issue 4, Page 1168-1190, February 2026.We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Genetic architecture of resistance to plant secondary metabolites in Photorhabdus entomopathogenic bacteria [PDF]
BMC GenomicsBackground Entomopathogenic nematodes of the genus Heterorhabditis establish a symbiotic association with Photorhabdus bacteria. Together, they colonize and rapidly kill insects, making them important biological control agents against agricultural pests.

A novel homoarginine-containing cyclic peptide pioamide with selective antipseudomonal activity isolated from the nematode symbiont Photorhabdus khanii [PDF]
Applied and Environmental MicrobiologyGram-negative bacteria harbor an outer membrane that physically protects them from the penetration of antibiotics into the cells. This barrier makes it challenging to develop antibiotics that effectively kill Gram-negative pathogens. The entomopathogenic

Computational modelling and sequence analysis provide new insights into the structure, function, and evolution of the pirB Gene in Photorhabdus, Xenorhabdus, and Vibrio species [PDF]
Journal of Advanced Veterinary and Animal ResearchObjective: To compare the structural and functional variations in the Photorhabdus insect-related B (pirB) genes of selected bacterial species such as Photorhabdus luminescens, Xenorhabdus doucetiae, and Vibrio parahaemolyticus.

Engineering Pseudomonas protegens as a Targeted Antifungal‐Effector Delivery Chassis via Heterologous Type III Secretion System Reconstitution [PDF]
Microbial Biotechnology, Volume 19, Issue 6, June 2026.A heterologous T3SS turns Pseudomonas protegens Pf‐5 into a programmable molecular syringe that delivers Bg9562 into Fusarium hyphae, suppresses fungal pathogens, enhances rhizosphere colonization and protects tomato plants from wilt. This modular platform offers a transferable strategy for next‐generation fungal biocontrol.

Molluscicidal property of symbiotic bacteria associated with entomopathogenic nematodes against Indoplanorbis exustus and Radix rubiginosa, the intermediate hosts of trematode parasites [PDF]
Parasite Epidemiology and ControlIndoplanorbis exustus and Radix rubiginosa act as intermediate hosts for veterinary and medical trematode parasites. Snail control is a strategy used to decrease the number of snails and interrupt the life cycle of parasites.
