Most aphids possess intracellular bacteria of the genus Buchnera. The bacteria are transmitted vertically via the aphid ovary, and the association is obligate for both partners: Bacteria-free aphids grow poorly and produce few or no offspring, and Buchnera are both unknown apart from aphids and apparently unculturable. The symbiosis has a nutritional basis. Specifically, bacterial provisioning of essential amino acids has been demonstrated. Nitrogen recycling, however, is not quantitatively…

Symbiotic microoiganisms in aphids (Homoptera, Insecta): A secret of one thriving insect group

Evidence suggests that Buchnera were acquired by a common ancestor of aphids 160–280 million years ago, and have been diversified, since then, in parallel with their aphid hosts, reflecting a nutritional role played by these symbionts.

Facultative bacterial symbionts in aphids confer resistance to parasitic wasps

Investigation of aphids for vulnerability of the aphid host to a hymenopteran parasitoid, Aphidius ervi, shows that infection confers resistance to parasitoids attack by causing high mortality of developing Parasitoid larvae.

Genome sequence of the endocellular bacterial symbiont of aphids Buchnera sp. APS

The results indicate that Buchnera is completely symbiotic and viable only in its limited niche, the bacteriocyte, and indicates complementarity and syntrophy between the host and the symbiont.

Spiroplasma affects host aphid proteomics feeding on two nutritional resources

How the aphid host proteome is differentially affected by Spiroplasma infection when the host is exploiting host plants with different nutritional values is discussed.

Genome of Buchnera sp. Aps, an Intracellular Symbiotic Bacterium of the Pea Aphid Acyrthosiphon Pisum

B Buchnera have lost most of the genes for biosynthesis of non-essential amino acids, and presumably depend on the host for these nutrients, and have never been observed in the association between parasitic bacteria such as Mycoplasma and Rickettsia and their hosts.

The impact of host plant on the abundance and function of symbiotic bacteria in an aphid.

It is proposed that the shortfall in threonine, possibly compounded by the high density of secondary symbionts, may contribute to the poor performance of the aphids on L. purpureum.

Unrelated facultative endosymbionts protect aphids against a fungal pathogen.

It is shown that protection against this entomopathogen, Pandora neoaphidis, can be conferred by strains of four distantly related symbionts (in the genera Regiella,Rickettsia, Rickettsiella and Spiroplasma), which reduce mortality and also decrease fungal sporulation on dead aphids which may help protect nearby genetically identical insects.

Disrupting Buchnera aphidicola, the endosymbiotic bacteria of Myzus persicae, delays host plant acceptance

Results indicate that B. aphidicola plays a role in plant–aphid interactions and the validity of the use of artificial diets in plant-aphid studies is discussed.



A consideration about the origin of aphid intracellular symbiont in connection with gut bacterial flora

One of the gut microbes belonging to the family Enterobacteriaceae was identified as Erwinia herbicola that is found mainly on plant surfaces, which may suggest that the intracellular symbiont of aphid is derived from a habitant of plant on which host insects feed.

The aphid‐bacterial symbiosis: a comparison between pea aphids and black bean aphids

Over the years, a variety of aphid species have been used to study the symbiosis with the bacteria Budinera, but recent research has focused almost exclusively on one species, the pea aphid Acyrthosiphon pisum.

Parallels and contrasts between symbiotic bacteria and bacterial-derived organelles: evidence from Buchnera, the bacterial symbiont of aphids

The congruence of the phylogenies of Buchnera and aphids, together with dating from the aphid fossil record, suggests that BuchnerA has been transmitted vertically down the aphids generations for 160–280 million years.

How symbiotic bacteria influence plant utilisation by the polyphagous aphid, Aphis fabae

It is proposed that the bacteria may be particularly important on plants with phloem sap of high amino acid content of low quality, i.e. low concentrations of essential amino acids, which may influence the contribution of the bacteria to plant utilisation.

Genetics, physiology, and evolutionary relationships of the genus Buchnera: intracellular symbionts of aphids.

Genetic and physiological studies indicate that Buchnera can synthesize methionine, cysteine, and tryptophan and supply these amino acids to the aphid host and involve plasmid-amplification of the gene coding for anthranilate synthase, the first enzyme of the tryptophile biosynthetic pathway.

Nitrogen recycling in the pea aphid (Acyrthosiphon pisum) symbiosis

Data suggest that the bacteria in aphids recycle aphid waste ammonia to essential amino acids, which are made available to the aphid tissues, which is linked to the very high ratio of non-essential : essential amino acid in phloem sap, the usual diet of aphids.

Populations of symbiotic bacteria in the parthenogenetic pea aphid (Acyrthosiphon pisum) symbiosis

The growth and division of the bacteria in the maternal tissues varied with aphid developmental age, with evidence for a restriction of bacterial division rates in fourth-instar larvae.

Observations on the micro‐organisms occurring in the gut of the pea aphid Acyrthosiphon pisum

In the course of a study on the primary symbiosis of the pea aphid Acyrthosiphon pisum, it is useful to further characterise the micro-organisms occurring in the aphid gut, and to comment on their possible origin and their presence at different ages and in two biotypes currently used in the laboratory.
