Microbial symbioses, in which microbes have either positive (mutualistic) or negative (parasitic) impacts on host fitness, are integral to all aspects of biology, from ecology to human health. In many well-studied cases, microbial symbiosis is characterized by a specialized association between a host and a specific microbe that provides it with one or more beneficial functions, such as novel metabolic pathways or defense against pathogens. Even in relatively simple associations, symbiont…

Symbiosis: Viruses as Intimate Partners.
TLDR
Putting viruses in this context provides an important framework for understanding virus-host relationships and virus ecology, and the presence of large amounts of viral sequence in the genomes of everything from bacteria to humans, illustrates the significance of viral symbiogenesis in the evolution of all life on Earth.
Intracellular Burkholderia Symbionts induce extracellular secondary infections; driving diverse host outcomes that vary by genotype and environment
TLDR
This study illuminates the phenomenon of co-infection induction across Dictyostelium associated Burkholderia species and exemplifies the contextual complexity of these associations.
pH Adaptation Drives Diverse Phenotypes in a Beneficial Bacterium-Host Mutualism
TLDR
Results imply that the evolution and diversification of Vibrio strains adapted to low pH outside the squid improves fitness inside the squid by allowing a higher success rate for host colonization and symbiotic competence.
Variation in the structure and function of invertebrate-associated bacterial communities
TLDR
The bacterial communities associated with Bactrocera oleae (the olive fruit fly) are described and draft genome sequences for several members of the gut microbiota are generated, including the symbiotic bacterium “Candidatus Erwinia dacicola” and a novel facultative bacterium Tatumella TA1.
Conditional fitness benefits of the Rickettsia bacterial symbiont in an insect pest
TLDR
Test results demonstrate the complex nature of these close symbiotic associations and the need to consider these interactions in the context of host population structure and help explain other reports of variation in the phenotype of the symbiosis.
Stress as a Normal Cue in the Symbiotic Environment.
Persistent Interactions with Bacterial Symbionts Direct Mature-Host Cell Morphology and Gene Expression in the Squid-Vibrio Symbiosis
TLDR
The mature bobtail squid, whose light-emitting organ, under experimental conditions, can be transiently or persistently colonized by Vibrio fischeri or remain uncolonized, provides a window into how persistent symbiotic colonization influences the form and function of host animal tissues.
Multiple mutualist effects: conflict and synergy in multispecies mutualisms.
TLDR
A synthesis of two approaches using graphical models to define the multiple mutualist effects (MMEs) that occur when a focal species has multiple partner mutualists illustrates how the consideration of MMEs can improve the ability to predict the outcomes of losses or gains of mutualisms from ecosystems.
Defensive symbiosis: a microbial perspective
TLDR
Microbial interactions with plants and animals are typi-cally invisible to the naked eye, but their impacts on hosts and host communities can be very large, and defensive mutualisms involving microbial sym-bionts often involve the production of toxic secondary metabolites.

Experimental evidence of a tripartite mutualism: bacteria protect ant fungus gardens from specialized parasites
TLDR
It is suggested that mutualisms between antibiotic-producing microbes and higher organisms may be common associations that are mostly overlooked and that the role of symbionts in reducing the impact of parasites is likely an important aspect in the cost-benefit assessment of mutualisms.
The Roles and Interactions of Symbiont, Host and Environment in Defining Coral Fitness
TLDR
These results highlight the complex interactions that occur between the coral host, the algal symbiont, and the environment to shape the fitness of the coral holobiont and will assist in predicting the responses of corals to global climate change.
Metabolic Complementarity and Genomics of the Dual Bacterial Symbiosis of Sharpshooters
TLDR
This study, which to the authors' knowledge is the first genomic analysis of an obligate symbiosis involving multiple partners, suggests striking complementarity in the biosynthetic capabilities of the two symbionts: B. cicadellinicola and S. muelleri, both isolated from H. coagulata.
Diversity and Genomes of Uncultured Microbial Symbionts in the Termite Gut

  • Biology, Environmental Science

  • 2010
TLDR
A combination of single-species-targeting metagenomics, conventional metagenetics, and metatranscriptomics should be a powerful tool to dissect this complex, multi-layered symbiotic system of termites.
Masters of conquest and pillage: Xenorhabdus nematophila global regulators control transitions from virulence to nutrient acquisition
TLDR
This review highlights regulatory cascades involved in coordinating transitions between various stages of the X.’nematophila life cycle: infection, reproduction and transmission and concludes that Xenorhabdus nematophILA is the best‐studied species of its genus with regard to the molecular mechanisms of its symbiotic associations.
Streptomyces as symbionts: an emerging and widespread theme?
TLDR
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.
Fungal endophytes: diversity and functional roles.
TLDR
It is shown that NC-endophytes represent three distinct functional groups based on host colonization and transmission, in planta biodiversity and fitness benefits conferred to hosts, and key questions for future work in endophyte biology are highlighted.
Autophagy regulates Wolbachia populations across diverse symbiotic associations
TLDR
It is shown that the activation of host nematode autophagy reduces bacterial loads to the same magnitude as antibiotic therapy; thus, a bactericidal mode of action targeting Wolbachia is identified that can be exploited for the development of chemotherapeutic agents against onchocerciasis, lymphatic filariasis, and heartworm.
Insect Symbioses: A Case Study of Past, Present, and Future Fungus-Growing Ant Research*
TLDR
The fungus-growing ant symbiosis serves as a particularly useful model system for studying insect-microbe symbioses, because, to date, it contains four well-characterized microbial symbionts, including mutualists and parasites that encompass micro-fungi, macro-funki, yeasts, and bacteria.
Endosymbiotic sulphate-reducing and sulphide-oxidizing bacteria in an oligochaete worm
TLDR
It is shown that in the gutless marine oligochaete Olavius algarvensis, endosymbiotic sulphate-reducing bacteria produce sulphide that can serve as an energy source for sulphide-oxidizing symbionts of the host.
