Xenortide Biosynthesis by Entomopathogenic Xenorhabdus nematophila

Journal of Natural Products, 2014
The biosynthesis gene cluster of the xenortides and a new derivative, xenortide D, which is produced in only trace amounts, was identified in Xenorhabdus nematophila. The structure of xenortide D was elucidated using a combination of labeling experiments followed by MS analysis and was confirmed by synthesis.

Genome Sequence Analysis of Native Xenorhabdus Strains Isolated from Entomopathogenic Nematodes in Argentina [PDF]

Toxins
Entomopathogenic nematodes from the genus Steinernema (Nematoda: Steinernematidae) are capable of causing the rapid killing of insect hosts, facilitated by their association with symbiotic Gram-negative bacteria in the genus Xenorhabdus (Enterobacterales:

Interspecific competition between entomopathogenic nematodes (Steinernema) is modified by their bacterial symbionts (Xenorhabdus)

BMC Evolutionary Biology, 2006
Background Symbioses between invertebrates and prokaryotes are biological systems of particular interest in order to study the evolution of mutualism.

Escherichia coli Nissle 1917 Occupies Previously Undocumented Host Niches in the Insect-Parasitic Nematode Steinernema hermaphroditum. [PDF]

Environ Microbiol Rep
This study characterizes previously undocumented host tissues in Steinernema nematodes, including putative coelomocytes, intestinal compartments, and inter‐cuticular spaces colonized by Escherichia coli Nissle 1917. Our findings reveal niche‐specific microbial interactions distinct from those with native symbionts, establishing a platform for ...

Determination of the Antifungal Effect of Bacterial Metabolites of Xenorhabdus szentirmaii Against Some Phytopathogenic Fungi

Düzce Üniversitesi Bilim ve Teknoloji Dergisi, 2022
This study was carried out to determine the antifungal effects of the supernatant produced by the bacterium Xenorhabdus szentirmaii, which is associated with soil-inhabiting entomopathogenic nematodes, on important plant pathogenic fungi, Fusarium ...

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo. [PDF]

Pest Manag Sci
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 ...

Lysogeny and bacteriocinogeny in Xenorhabdus nematophilus and other Xenorhabdus spp [PDF]

Applied and Environmental Microbiology, 1992
Induction by mitomycin or high-temperature treatment resulted in the production of bacteriocins and phages in both phases of Xenorhabdus nematophilus A24, indicating lysogeny. Phage DNA purified from X. nematophilus A24 hybridized to several fragments of DraI-digested A24 chromosomal DNA, confirming that the phage genome was incorporated into the ...

Transformation of Xenorhabdus nematophilus [PDF]

Applied and Environmental Microbiology, 1989
The ability of Xenorhabdus nematophilus 19061/1 to be transformed by pHK17 plasmid DNA was studied and optimized. A number of factors, including culture conditions, stage of growth, transformation buffer pH, cation type and concentration required for the production of competency, washing, heat shock conditions, and cell-DNA ratio, were found to affect ...

Steinernema africanum n. sp. (Rhabditida, Steinernematidae), a New Entomopathogenic Nematode Species Isolated in the Republic of Rwanda

Journal of Nematology, 2022
Alternatives to hazardous insecticides are urgently needed for an environmentally friendly and effective management of insect pests. One such option is the use of entomopathogenic nematodes (EPN).

Multigene Sequence-Based and Phenotypic Characterization Reveals the Occurrence of a Novel Entomopathogenic Nematode Species, Steinernema anantnagense n. sp.

Journal of Nematology, 2023
Three entomopathogenic nematode populations were isolated from agricultural fields in the Anantnag district of Jammu and Kashmir (India). Sequences of multiple gene regions and phenotypic features show that they are conspecific and represent a novel ...
