Nutritional interactions in insect-microbial symbioses: aphids and their symbiotic bacteria Buchnera.
  • A. Douglas
  • Biology, Medicine
  • Annual review of entomology
  • 1998
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 aphidsExpand

  • Journal of experimental botany
  • 1 March 2006
The incidence of phloem sap feeding by animals appears paradoxical. Although phloem sap is nutrient-rich compared with many other plant products and generally lacking in toxins and feedingExpand

Animals in a bacterial world, a new imperative for the life sciences
In the last two decades, the widespread application of genetic and genomic approaches has revealed a bacterial world astonishing in its ubiquity and diversity. This review examines how a growingExpand

Photosynthetic symbioses in animals.
Animals acquire photosynthetically-fixed carbon by forming symbioses with algae and cyanobacteria. These associations are widespread in the phyla Porifera (sponges) and Cnidaria (corals, sea anemonesExpand

The microbial dimension in insect nutritional ecology
Summary 1Many insects derive nutritional advantage from persistent associations with microorganisms that variously synthesize essential nutrients or digest and detoxify ingested food. TheseExpand

The secreted salivary proteome of the pea aphid Acyrthosiphon pisum characterised by mass spectrometry
Nine proteins secreted in the saliva of the pea aphid Acyrthosiphon pisum were identified by a proteomics approach using GE‐LC‐MS/MS and LC‐MS/MS, with reference to EST and genomic sequence data forExpand

Low-diversity bacterial community in the gut of the fruitfly Drosophila melanogaster.
The bacteria in the fruitfly Drosophila melanogaster of different life stages was quantified by 454 pyrosequencing of 16S rRNA gene amplicons. The sequence reads were dominated by 5 operationalExpand

A water-specific aquaporin involved in aphid osmoregulation.
The osmotic pressure of plant phloem sap is generally higher than that of insect body fluids. Water cycling from the distal to proximal regions of the gut is believed to contribute to theExpand

Linking the bacterial community in pea aphids with host‐plant use and natural enemy resistance
Abstract.  1. Pea aphids, Acyrthosiphon pisum, harbour a range of facultative accessory bacteria (secondary symbionts), including those informally known as PASS (R‐type), PAR, PABS (T‐type), and PAUSExpand
