Antimicrobial Metabolites from a Bacterial Symbiont

Journal of Natural Products, 1995
Two types of antibiotics, namely, indoles and dithiolopyrrolones, have been isolated and identified from Xenorhabdus bovienii A2. Compounds 1 and 2 showed strong activity against Cryptococcus neoformans, compounds 3 and 4 showed strong activity against Botrytis cinerea, and compounds 1, 3, and 4 showed significant activity against Phytophthora ...

Genomics and Evolution of Heritable Bacterial Symbionts

Annual Review of Genetics, 2008
Insect heritable symbionts have proven to be ubiquitous, based on molecular screening of various insect lineages. Recently, molecular and experimental approaches have yielded an immensely richer understanding of their diverse biological roles, resulting in a burgeoning research literature.

Tephritidae bacterial symbionts: potentials for pest management

Bulletin of Entomological Research, 2019
AbstractTephritidae is a large family that includes several fruit and vegetable pests. These organisms usually harbor a variegated bacterial community in their digestive systems. Symbiotic associations of bacteria and fruit flies have been well-studied in the generaAnastrepha, Bactrocera, Ceratitis,andRhagoletis.Molecular and culture-based techniques ...

How Legumes Let in Bacterial Symbionts

Science, 2003
The complex interplay between bacterium and plant that results in nodulation of legumes--and thus the facility for the symbiosis to fix nitrogen--depends on the Nod factors, lipo-chitooligosaccharides of a variety of distinctive specificities. Limpens et al.

Bacterial Symbionts in Pogonophora

Journal of the Marine Biological Association of the United Kingdom, 1982
Prokaryote organisms, with characteristics of Gram-negative bacteria, occur intracellularly in Pogonophora, as described here for seven small species. The tissue containing the bacteria lies between the two longitudinal blood vessels in the posterior part of the trunk and has a special blood supply. This tissue is probably homologous with the so-called

Do Bacterial Symbionts Govern Aphid's Dropping Behavior?

Environmental Entomology, 2015
Defensive symbiosis is amongst nature's most important interactions shaping the ecology and evolution of all partners involved. The pea aphid, Acyrthosiphon pisum Harris (Hemiptera: Aphididae), harbors one obligatory bacterial symbiont and up to seven different facultative symbionts, some of which are known to protect the aphid from pathogens, natural ...

Genetic transformation and phylogeny of bacterial symbionts from tsetse

Insect Molecular Biology, 1993
Abstract Two isolates of bacterial endosymbionts, GP01 and GM02, were established in cell free medium from haemolymph of the tsetse, Glossina pallidipes and G. morsitans. These microorganisms appear similar to rickettsia‐like organisms
