A new recombineering system for Photorhabdus and Xenorhabdus
Precise and fluent genetic manipulation is still limited to only a few prokaryotes. Ideally the highly advanced technologies available in Escherichia coli could be broadly applied. Our efforts to apply lambda Red technology, widely termed 'recombineering', in Photorhabdus and Xenorhabdus yielded only limited success. Consequently we explored the properties of an endogenous Photorhabdus luminesc...
متن کاملMolecular identification and genetic diversity among Photorhabdus and Xenorhabdus isolates
Five bacterial strains were isolated from the hemocoel of the greater wax moth larvae (Galleria mellonella) infected with the entomopathogenic nematodes: Heterorhabditis bacteriophora HP88, Heterorhabditis indicus RM1 and Heterorhabditis sp (S1), Steinernema abbasi and Steinernema sp. (S II). Strains were identified as Photorhabdus luminescens HRM1, P. luminescens HS1, P. luminescens HP88, Xeno...
متن کاملInsecticidal Toxins from the Photorhabdus and Xenorhabdus Bacteria
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 genomic goldmine, encoding a multitude of insecticidal toxins. Some are highly specific in their target species, whilst others are more generalist, but all are of potential use in crop protection against insect pests...
متن کاملTxp40, a ubiquitous insecticidal toxin protein from Xenorhabdus and Photorhabdus bacteria.
Xenorhabdus and Photorhabdus are gram-negative bacteria that produce a range of proteins that are toxic to insects. We recently identified a novel 42-kDa protein from Xenorhabdus nematophila that was lethal to the larvae of insects such as Galleria mellonella and Helicoverpa armigera when it was injected at doses of 30 to 40 ng/g larvae. In the present work, the toxin gene txp40 was identified ...
متن کاملAntibacterial Activities of Extracellular Metabolites of Symbiotic Bacteria, Xenorhabdus and Photorhabdus Isolated from Entomopathogenic Nematodes
Xenorhabdus and Photorhabdus are members of the family Enterobacteriaceae, and are engaged in a mutualistic association with the entomopathogenic nematodes, Steinernema and Heterorhabditis, respectively. In the present study, the organic fraction of ethyl acetate bacterial crude extracts of the symbiotic bacteria, Xenorhabdus stockiae and Photorhabdus luminescens isolated from entomopathogenic ...
