Combinatorial effect of Bacillus thuringiensis kurstaki and Photorhabdus luminescens against Spodoptera littoralis (Lepidoptera: Noctuidae)

Journal of Basic Microbiology, 2014
Spodoptera littoralis, one of the major pests of many important crop plants, is more susceptible to Bacillus thuringiensis aizawai delta-endotoxins than to those of Bacillus thuringiensis kurstaki.

A syringe-like injection mechanism in Photorhabdus luminescens toxins [PDF]

Nature, 2013
Photorhabdus luminescens is an insect pathogenic bacterium that is symbiotic with entomopathogenic nematodes. On invasion of insect larvae, P. luminescens is released from the nematodes and kills the insect through the action of a variety of virulence factors including large tripartite ABC-type toxin complexes (Tcs).

Photorhabdus Luminescens: Virulent Properties and Agricultural Applications [PDF]

Journal of Agriculture and Forestry (New York, N Y ), 2015
Photorhabdus luminescens is a gram-negative, bioluminescent bacterium from the family Enterobacteriaceae which has been found in countries across the globe. It is part of a symbiotic relationship with, and resides in the gut of the entomopathogenic nematode, Heterorhabditis bacteriophora.

Two new Subspecies of Photorhabdus luminescens, Isolated from Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae): Photorhabdus luminescens subsp. kayaii subsp. nov. and Photorhabdus luminescens subsp. thracensis subsp. nov.

Systematic and Applied Microbiology, 2004
Bacterial isolates from nematodes from Turkish soil samples were initially characterized by molecular methods and seven members of the genus Photorhabdus identified to the species level, using riboprint analyses and metabolic properties. Strain 07-5 (DSM 15195) was highly related to the type strain of Photorhabdus luminescens subsp.

Expression and activity of a probable toxin from Photorhabdus luminescens

Molecular Biology Reports, 2008
As an insect pathogen, Photorhabdus luminescens possesses an arsenal of toxins. Here we cloned and expressed a probable toxin from P. luminescens subsp. akhurstii YNd185, designated as Photorhabdus insecticidal toxin (Pit). The pit gene shares 94% nucleotide and 98% predicted amino acid sequence identity with plu1537, a predicted ORF from P ...

Generation of thermostable monomeric luciferases from Photorhabdus luminescens

Biochemical and Biophysical Research Communications, 2002
Bacterial luciferases and the genes encoding these light-emitting enzymes have an increasing number of applications in biological sciences. Temperature lability and the heterodimeric nature of these luciferases have been the major obstacles for their widespread use, for instance, as genetic reporters.

Insecticidal Toxins from the Bacterium Photorhabdus luminescens

Science, 1998
Transgenic plants expressing Bacillus thuringiensis (Bt) toxins are currently being deployed for insect control. In response to concerns about Bt resistance, we investigated a toxin secreted by a different bacterium Photorhabdus luminescens, which lives in the gut of entomophagous nematodes ...

Insecticidal Toxin Complexes from Photorhabdus luminescens

2016
Various bacterial toxins have potent insecticidal activity. Recently, the Toxin complexes (Tc's) of Photorhabdus and Xenorhabdus species have become an increased focus of current research. These large tripartite toxins with molecular masses >1.4 megadaltons consist of three components termed A, B, and C (or TcA, TcB, and TcC).

Trans-specific nematicidal activity of Photorhabdus luminescens

Nematology, 1999
Abstract Mixed culture filtrates of Photorhabdus luminescens isolated from Heterorhabditis bacteriophora H06 and from H. indica LN2 had a toxic effect on axenic H. bacteriophora H06 dauer juveniles. Single culture filtrates had no effect.
