Streptomyces as symbionts: an emerging and widespread theme?
This work reviews what is currently known about the role of streptomycetes as symbionts with fungi, plants and animals and suggests that this field of research will become increasingly important as the search for new antibiotics switches to unusual and under-explored environments. Expand
Symbiotic Bacteria Protect Wasp Larvae from Fungal Infestation
This is the first report on the cultivation of bacteria in insect antennae and the first case of a symbiosis involving bacteria of the important antibiotic-producing genus Streptomyces, which might play an important role in other insects as well. Expand
Geographical and ecological stability of the symbiotic mid‐gut microbiota in European firebugs, Pyrrhocoris apterus (Hemiptera, Pyrrhocoridae)
It is suggested that the firebug mid‐gut microbiota constitutes a functionally important and possibly coevolved symbiotic community. Expand
The digestive and defensive basis of carcass utilization by the burying beetle and its microbiota
This work uses burying beetles to investigate the digestive and defensive basis of carrion utilization, and finds a strict functional compartmentalization of the gut involving differential expression of immune effectors, as well as digestive and detoxifying enzymes. Expand
Symbiotic Streptomycetes provide antibiotic combination prophylaxis for wasp offspring.
The complementary action of all symbiont-produced antibiotics confers a potent antimicrobial defense for the wasp larvae that parallels the 'combination prophylaxis' known from human medicine. Expand
Actinobacteria as mutualists: general healthcare for insects?

  • 1 December 2009
Defensive mutualisms with actinobacteria might constitute a general and widespread theme in the ecology and evolution of arthropods, and the study of the secondary metabolites involved promises to uncover novel drug candidates for human medicine. Expand
Bacterial Symbionts in Lepidoptera: Their Diversity, Transmission, and Impact on the Host
It is found that routes of transmission of both gut microbiota and intracellular symbionts may be horizontally transmitted through the host plant, but also vertically via the egg stage and more detailed knowledge about the functions and plasticity of the microbiome in Lepidoptera may provide novel leads for the control of lepidopteran pest species. Expand
Symbiont Acquisition and Replacement as a Source of Ecological Innovation.
The known ecological and evolutionary implications of symbiont gains, switches, and replacements are reviewed, and future research directions that can contribute to a more comprehensive understanding of symbiosis as a major driving force of ecological adaptation are identified. Expand
Unearthing carrion beetles' microbiome: characterization of bacterial and fungal hindgut communities across the Silphidae
Despite the possibility for vertical transmission via anal secretions, the distinct hindgut microbiota of the Silphidae appears to be shaped by frequent horizontal exchange or environmental uptake of symbionts, and both the fungal symbiont phylogeny and distance‐based bacterial community clustering showed higher congruence with sampling locality than host phylogeny. Expand
Defensive symbioses of animals with prokaryotic and eukaryotic microorganisms.
The described protective symbioses between animals and bacteria, fungi, and dinoflagellates are reviewed to derive general patterns on the chemistry, ecology, and evolution of such associations. Expand
