Characterization of the pleiotropic phenotype of an ompR strain of Xenorhabdus nematophila

Antonie van Leeuwenhoek, 2002
Xenorhabdus nematophila is an insect pathogen that forms a symbiotic association with the nematode, Steinernema carpocapsae. Xenorhabdus is carried into the insect host by the nematode, is released into the hemolymph and participates in killing the insect.

The hipBAXn operon from Xenorhabdus nematophila functions as a bonafide toxin-antitoxin module

Applied Microbiology and Biotechnology, 2020
Here, for the first time, we have investigated the hipBAXn toxin-antitoxin (TA) module from entomopathogenic bacterium Xenorhabdus nematophila. It is a type II TA module that consists of HipAXn toxin and HipBXn antitoxin protein and located in the complementary strand of chromosome under XNC1_operon 0810 locus tag. For functional analysis, hipAXn toxin,

Structure elucidation and biosynthesis of lysine-rich cyclic peptides in Xenorhabdus nematophila

Organic & Biomolecular Chemistry, 2011
Thirteen novel PAX (peptide-antimicrobial-Xenorhabdus) peptides were identified in Xenorhabdus nematophila HGB081. Their structures including the absolute configuration were elucidated using a combination of labeling experiments, detailed MS/MS experiments, the advanced Marfey's method, and a detailed analysis of the biosynthesis gene cluster, which ...

Unique organization and regulation of the mrx fimbrial operon in Xenorhabdus nematophila

Microbiology, 2004
Xenorhabdus nematophila, a Gram-negative bacterium belonging to the Proteus clade of the family Enterobacteriaceae, forms a mutualistic association with the soil nematode Steinernema carpocapsae. The nematode invades insects and releases Xenorhabdus into the haemolymph, where it participates in insect killing.

Sequential immunosuppressive activities of bacterial secondary metabolites from the entomopahogenic bacterium Xenorhabdus nematophila

Journal of Microbiology, 2014
The entomopathogenic bacterium Xenorhabdus nematophila secretes at least eight bacterial metabolites that play crucial roles suppressing target insect immune responses by inhibiting eicosanoid biosynthesis. We analyzed sequential changes in bacterial metabolite production during bacterial growth and analyzed their individual immunosuppressive ...

[Purification and characterization of the haemocoel insecticide Tp40 from Xenorhabdus nematophila].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2009
Xenorhabdus nematophila is an insect pathogen bacterium symbiotically associated with entomopathogenic nematode. The bacteria produce a number of toxins to overcome immune response of insect hosts and kill their hosts. We purified a novel haemocoel insecticidal protein from X.

A novel insecticidal GroEL protein from Xenorhabdus nematophila confers insect resistance in tobacco

Transgenic Research, 2013
Xenorhabdus nematophila is an entomopathogenic bacteria. It secretes a GroEL homolog, XnGroEL protein, toxic to its larval prey. GroEL belongs to the family of molecular chaperones and is required for proper folding of cellular proteins. Oral ingestion of insecticidal XnGroEL protein is toxic to Helicoverpa armigera, leading to cessation of growth and ...

The role of pilin protein of Xenorhabdus nematophila against immune defense reactions of insects

Journal of Insect Physiology, 2017
Xenorhabdus nematophila is a symbiotic bacterium of the entomopathogenic nematode Steinernema carpocapsae (Weiser). It produces several toxic proteins which interfere with the immune system of insects. The current study shows that purified pilin protein could be a virulence trait of X. nematophila.

Flagellar Regulation and Virulence in the Entomopathogenic Bacteria—Xenorhabdus nematophila and Photorhabdus luminescens

2016
There is a complex interplay between the regulation of flagellar motility and the expression of virulence factors in many bacterial pathogens. Here, we review the literature on the direct and indirect roles of flagellar motility in mediating the tripartite interaction between entomopathogenic bacteria (Photorhabdus and Xenorhabdus), their nematode ...
