Photorhabdus luminescens genes induced upon insect infection [PDF]

BMC Genomics, 2008
Background Photorhabdus luminescens is a Gram-negative luminescent enterobacterium and a symbiote to soil nematodes belonging to the species Heterorhabditis bacteriophora. P.luminescens is simultaneously highly pathogenic to insects.

Entomopathogenic Nematodes and Bioactive Compounds of Their Bacterial Endosymbionts Act Synergistically in Combination with Spinosad to Kill Phthorimaea operculella (Zeller, 1873) (Lepidoptera: Gelechiidae), a Serious Threat to Food Security [PDF]

Microorganisms
As a staple food, potato (Solanum tuberosum L.) (Solanaceae) is one of the most produced food crops to ensure food security. The potato tuber moth (PTM), Phthorimaea operculella (Zeller, 1873) (Lepidoptera: Gelechiidae), is a major pest of potato ...

Biological control of Schistocerca gregaria and Locusta migratoria migratorioides using Entomopathogenic bacteria [PDF]

Scientific Reports
This study investigated the potential of indigenous entomopathogenic bacterial (EPB) strains from Egypt to control the two most prevalent locust species, Schistocerca gregaria (Forsskål) (Orthoptera: Acrididae), and Locusta migratoria migratorioides ...

Pyrazinone protease inhibitor metabolites from Photorhabdus luminescens. [PDF]

J Antibiot (Tokyo), 2016
Photorhabdus luminescens is a bioluminescent entomopathogenic bacterium that undergoes phenotypic variation and lives in mutualistic association with nematodes of the family Heterorhabditidae. The pair infects and kills insects, and during their coordinated lifecycle, the bacteria produce an assortment of specialized metabolites to regulate its ...

Ail and PagC-related proteins in the entomopathogenic bacteria of Photorhabdus genus. [PDF]

PLoS ONE, 2014
Among pathogenic Enterobacteriaceae, the proteins of the Ail/OmpX/PagC family form a steadily growing family of outer membrane proteins with diverse biological properties, potentially involved in virulence such as human serum resistance, adhesion and ...

Photorhabdus lux-operon heat shock-like regulation

Heliyon, 2023
For decades, transcription of Photorhabdus luminescens lux-operon was considered being constitutive. Therefore, this lux-operon has been used for measurements in non-specific bacterial luminescent biosensors.

A study on Xenorhabdus and Photorhabdus isolates from Northeastern Thailand: Identification, antibacterial activity, and association with entomopathogenic nematode hosts.

PLoS ONE, 2021
Xenorhabdus and Photorhabdus are gram negative bacteria that can produce several secondary metabolites, including antimicrobial compounds. They have a symbiotic association with entomopathogenic nematodes (EPNs).

Two Philippine Photorhabdus luminescens strains inhibit the in vitro growth of Lasiodiplodia theobromae, Fusarium oxysporum f. sp. lycopersici, and Colletotrichum spp.

Egyptian Journal of Biological Pest Control, 2021
Background Fungal phytopathogens are one of the leading causes of loss in global food production. Chemical fungicides have always been used to control the phytopathogens to mitigate losses.

Entomopathogenic Nematodes and Their Symbiotic Bacteria from the National Parks of Thailand and Larvicidal Property of Symbiotic Bacteria against Aedes aegypti and Culex quinquefasciatus

Biology, 2022
Entomopathogenic nematodes (EPNs) are insect parasitic nematodes of the genera Het-erorhabditis and Steinernema. These nematodes are symbiotically associated with the bacteria, Photorhabdus and Xenorhabdus, respectively.

Freund oder Feind? — Die zwei Gesichter von Photorhabdus luminescens [PDF]

BIOspektrum, 2021
AbstractPhotorhabdus luminescens is an enteric bacterium with two faces: on the one hand these bacteria live in symbiosis with soil nematodes, on the other hand they are highly pathogenic for insects. The population is also phenotypically heterogeneous: one part lives in symbiosis with nematodes, the other part symbiotically interacts with plants. Cell-
