Trade-offs shape the evolution of the vector-borne insect pathogen Xenorhabdus nematophila. [PDF]
Proc Biol Sci, 2012 Our current understanding on how pathogens evolve relies on the hypothesis that pathogens' transmission is traded off against host exploitation. In this study, we surveyed the possibility that trade-offs determine the evolution of the bacterial insect pathogen, Xenorhabdus nematophila .

BMC Genomics, 2017 Background Xenorhabdus innexi is a bacterial symbiont of Steinernema scapterisci nematodes, which is a cricket-specialist parasite and together the nematode and bacteria infect and kill crickets. Curiously, X.

The evolution of entomopathogeny in nematodes
Ecology and Evolution, Volume 14, Issue 2, February 2024.Through convergent evolution, the entomopathogeny in nematodes is widespread within the Rhaditidae families, owing to the shared ecological and evolutionary attributes raised from saprophagy, phoresis, and necromeny. Abstract Understanding how parasites evolved is crucial to understand the host and parasite interaction.

nilR is necessary for co‐ordinate repression of Xenorhabdus nematophila mutualism genes [PDF]
Molecular Microbiology, 2006 SummaryThe bacterial mutualist Xenorhabdus nematophila colonizes a specific region of its nematode host Steinernema carpocapsae. We previously reported the identification of a chromosomal locus encoding three X. nematophila genes of unknown function, nilA, B and C, that are each necessary for colonization. Subsequent work indicated the global regulator

Unveiling a CAAX Protease‐Like Protein Involved in Didemnin Drug Maturation and Secretion
Advanced Science, Volume 11, Issue 4, January 26, 2024.The functions of enzymes involved in both assembling and cleaving the acylated peptide prodrug structures in didemnin biosynthesis are elucidated. This process plays a crucial role in the maturation and secretion of didemnin drugs. The findings not only illuminate the intricate prodrug release mechanism governing the production of didemnin compounds ...

mBio, 2019 Bacterial infections are often composed of cells with distinct phenotypes that can be produced by genetic or epigenetic mechanisms. This phenotypic heterogeneity has proved to be important in many pathogens, because it can alter both pathogenicity and ...

A Comparative Analysis of Different Xenorhabdus Strains Reveals a Virulent Factor, Cyclic Pro-Phe, Using a Differential Expression Profile Analysis of Non-Ribosomal Peptide Synthetases. [PDF]
InsectsEntomopathogenic bacteria, classified into the genus Xenorhabdus, exhibit a dual lifestyle as mutualistic symbionts to Steinernema nematodes and as pathogens to a broad range of insects.

RNAseq Analysis of the Drosophila Response to the Entomopathogenic Nematode Steinernema
G3: Genes, Genomes, Genetics, 2017 Drosophila melanogaster is an outstanding model to study the molecular and functional basis of host–pathogen interactions. Currently, our knowledge of microbial infections in D.
