Sequence analysis of insecticidal genes from Xenorhabdus nematophilus PMFI296

Article Abstract:

The bacterium Xenorhabdus nematophilus contains two cosmid clones that code for insecticidal proteins. The cHRIM1 cosmid contains a gene whose product is an effective insecticide when expressed individually in E. coli.

Identification, typing, and insecticidal activity of Xenorhabdus isolates from entomopathogenic nematodes in United Kingdom soil and characterization of the xpt toxin loci

Article Abstract:

The insect bait entrapment technique was used to isolate Xenorhabdus strains from entomopathogenic nematodes from the United Kingdom soils and were characterized by partial sequencing of the 16S rRNA gene, four housekeeping genes (asd, ompR, recA, and serC) and the flagellin gene (fliC). It was found that most of the strains were similar to Xenorhabdus bovienii, and the remaining six had genes had genes most similar t those of Xemorhabdus nematophila.
