Regulating Alternative Lifestyles in Entomopathogenic Bacteria
Bacteria belonging to the genera Photorhabdus and Xenorhabdus participate in a trilateral symbiosis in which they enable their nematode hosts to parasitize insect larvae. The bacteria switch from persisting peacefully in a nematode's digestive tract to a lifestyle in which pathways to produce insecticidal toxins, degrading enzymes to digest the insect for consumption, and antibiotics to ward of...
متن کاملSmall molecule perimeter defense in entomopathogenic bacteria.
Two gram-negative insect pathogens, Xenorhabdus nematophila and Photorhabdus luminescens, produce rhabduscin, an amidoglycosyl- and vinyl-isonitrile-functionalized tyrosine derivative. Heterologous expression of the rhabduscin pathway in Escherichia coli, precursor-directed biosynthesis of rhabduscin analogs, biochemical assays, and visualization using both stimulated Raman scattering and confo...
متن کاملPromoting Healthy Lifestyles: Alternative Models' Effects (PHLAME).
The Promoting Healthy Lifestyles: Alternative Models' Effects (PHLAME) study evaluates the efficacy of two intervention strategies for improving nutrition and physical activity practices in fire fighters: a team-centered program and a one-on-one format targeting the individual. PHLAME compares these two behavior change models (the team-based versus the one-on-one approaches) against a usual-car...
متن کاملEmerging entomopathogenic bacteria for insect pest management
The scientific community working in the field of insect pathology is experiencing an increasing academic and industrial interest in the discovery and development of new bioinsecticides as environmentally friendly pest control tools to be integrated, in combination or rotation, with chemicals in pest management programmes. In this scientific context, market data report a 15% annual growth of the...
متن کاملSafety and ecotoxicology of entomopathogenic bacteria
Bacillus entomopathogens, especially Bacillus thuringiensis, have been used extensively for control of insect pests in crops, forests, and the aquatic environment. Their safety for vertebrates and nontarget invertebrates has been thoroughly documented in a myriad of studies. Their short term effects on nontarget organisms that are unrelated to target insects is negligible. However, the effect o...
