Hamiltonella

Pseudomonadota
Bacteria
Intracellular

The ability of B. tabaci Q to acquire, retain, and transmit TYLCV is affected by its S-symbiont Hamiltonella.
Virus Interaction

2013
Bacteria

Candidatus Moranella endobia is responsible for the biosynthesis of most cellular components and energy provision, and controls most informational processes for the consortium.
Nutrient Provision

Bacteria
Intracellular

Candidatus Hamiltonella defensa confers protection against parasitoid wasps.
Natural Enemy Resistance

2013
Bacteria
Intracellular

Hamiltonella phage APSE confers protection against parasitoid wasps, but only when Candidatus Hamiltonella defensa is itself infected by the phage.
Natural Enemy Resistance

Regiella insecticola

Pseudomonadota
Bacteria
Intracellular

Candidatus Regiella insecticola protects pea aphids from the aphid-specific fungal entomopathogen Zoophthora occidentalis but not from the generalist insect fungal pathogen Beauveria bassiana.
Pathogen Resistance

Sodalis glossinidius

Pseudomonadota

Glossina palpalis

Cameroon, Angola, B…

Bacteria
Extracellular

Sodalis glossinidius is associated with a three-times greater probability of the host flies being infected by trypanosomes (i.e., this symbiont may facilitate pathogen infection rather than confer resistance).
Pathogen Resistance

Klebsiella pneumonia

Pseudomonadota
Bacteria
Extracellular

Klebsiella pneumonia provides nitrogen fixation to hosts, which is beneficial for desert environments.
Nitrogen Fixation

2013
Regiella

Pseudomonadota
Bacteria
Intracellular

Regiella (in Acyrthosiphon pisum) protects against the entomopathogen Pandora neoaphidis by reducing mortality and decreasing fungal sporulation on dead aphids.
Pathogen Resistance

Xenorhabdus bovienii

Pseudomonadota
Bacteria
Extracellular

Xenorhabdus bovienii has the gene PIN1 encoding a protease inhibitor protein active against aphids.
Plant Defense Modulation

Sulcia muelleri

Pseudomonadota
Bacteria
Intracellular

Candidatus Sulcia muelleri is essential for nymphal growth and adult emergence; nymphs treated with antibiotics were remarkably retarded, died, or failed to attain adulthood.
Growth Regulation

The bacterium symbiont of Matsumuratettix hiroglyphicus is essential for nymphal growth and adult emergence; nymphs treated with antibiotics were remarkably retarded, died, or failed to attain adulthood.

Serratia symbiotica SAp is closely related to an obligate endosymbiont and is involved in the provision of amino acids.

Hamiltonella defensa

Pseudomonadota

Aphis fabae

Switzerland

Bacteria
Intracellular

Hamiltonella defensa (in Aphis fabae) suggests a high specificity of symbiont-conferred resistance, where parasitoids preferentially attack the youngest host stages or discriminate against protected aphids.
