Photorhabdus is a member of the family Enterobacteriaceae that lives in a mutualistic
association with a Heterorhabditis nematode worm. The nematode worm burrows into insect …

Most of the insecticidal toxins used in agriculture come from a single bacterium Bacillus
thuringiensis or 'Bt'. Here we review our work on the array of toxins produced by …

Pseudomonas fluorescens CHA0 and the related strain Pf‐5 are well‐characterized
representatives of rhizosphere bacteria that have the capacity to protect crop plants from …

Two recently sequenced genomes of the insect-pathogenic bacterium Photorhabdus and a
large Serratia entomophila plasmid, pADAP, have phage-related loci containing putative …

Insect pathogens are an excellent source of novel insecticidal agents with proven toxicity. In
particular, bacteria from the genera Photorhabdus and Xenorhabdus are proving to be a …

The bacterial Makes caterpillars floppy 1 (Mcf1) toxin promotes apoptosis in insects, leading
to loss of body turgor and death. The molecular mechanism underlying Mcf1 intoxication is …

The repeats-in-toxin (RTX) exoproteins are a diverse collection of proteins exported via type
I secretion by gram-negative bacteria. These proteins include the pore-forming RTX toxins …

Multifunctional-autoprocessing repeats-in-toxin (MARTX) toxins are a heterogeneous group
of toxins found in a number of Vibrio species and other Gram-negative bacteria. The toxins …

Photorhabdus is a highly effective insect pathogen and symbiont of insecticidal nematodes.
To exert its potent insecticidal effects, it elaborates a myriad of toxins and small molecule …
