Description
Pea aphids are a major agricultural pest, feeding on a variety of legumes (Fabaceae) worldwide. Plant phloem sap feeding insects such as pea aphids depend on their obligate endosymbionts to furnish them with essential amino acids and/or vitamin cofactors. Pea aphids have only one major, often sole microbial symbiont, Buchnera, a maternally-transmitted gammaproteobacteria related to the Enterobacteriaceae. Depending on the aphid-Buchnera pair the capacity to synthesize at least 5 essential amino acids can be shared between the 2 partners. The aphid-Buchnera association has persisted for at least 160 million years and is obligate for both partners. This strain is an endosymbiont of the pea aphid Acyrthosiphon pisum, and was isolated from aphids growing on Vicia faba (L.) (adapted from PMIDs 10993077 and 21392141). Buchnera from A. pisum and S. graminum have a three membrane system (one originating from the host, see PMID 22229056).
